Fun Fact: Leech

Anatomy Def: The leech is a segmented parasitic worm, closely related to the earthworm. Leech also means a doctor or healer. Who knew? 😜

Outlander Def: “Get-them-off!” William Ransom, eighth Earl of Ellesmere, demands Claire free his limbs of the ghastly creatures!

Learn about blood, the sumptuous repast of leeches, in Anatomy Lesson #37, “Outlander Owies Part 3 – Mars and Scars.”

Ahhhh, now you may think leeches boring, if so, I think you could be wrong. Here are fascinating fun facts about leeches:

      • More than 700 species
      • Soft, muscular bodies that lengthen and shorten during movement
      • Most have front and back suckers
      • Three sharp blades to cut flesh sit under front sucker
      • Saliva contains  hirudin, anticoagulant peptide (short amino acid chain)
      •  Used in bloodletting for at least 2,500 yrs
      • Hemaphrodite – each has one female organ and 9 pairs of testes. 😳
      • Appear in Proverbs 30:15 as an archetype of insatiable greed!

Bloodletting via leech is a time-honored practice dating to ancient Greece and India. Throughout Europe, the medicinal leech, Hirudo medicinalis, was used on ailing patients to rebalance body humors.

Yet more reasons this episode was titled “Blood of My Blood!!!” 😱

In 18th and 19th century Britain, leech-gatherers travelled the marshes gathering leeches from the wild. The practice became so widespread, the population was decimated in many areas. Bloody little buggers! 😈

In Old English, lǣce, was not only the name of the animal but also referred to a physician, and lǣcecraft or leechcraft described the art of healing. Hum….

Beginning in about 1980, leeches enjoyed a resurgence in modern medicine. Today, many hospitals stock them to treat:

      • Joint disease such as epicondylitis and osteoarthritis
      • Vein diseases of the extremities
      • Microsurgery
      • Blood-clotting disorders using hirudin

WARNING! If you sport a strong wame, watch this PBS video of how a leech attaches, how it feeds and its use in modern medicine. Watch at your own discretion.  There will be blood!!!  😷

Important! A leech can be removed by breaking the seal of front and back suckers with a fingernail or other flat, blunt object, flicking the leech away. Irritating the leech with a cigarette, vinegar, salt or soap may cause it to regurgitate stomach contents into the wound and transmit pathogens to its victim. Not common, but it has been reported. 

Read about leeches in The Drums of Autumn as Lord John Grey and his “son,” William Ransom, arrive unannounced at Fraser’s Ridge. Make no mistake, Claire recognizes Jamie’s get! 😉

Blundering out of the stream, I shoved my way through the tangled branches, and burst through into the clear space beyond. A boy was dancing on the bank above me, slapping madly at his legs and howling as he hopped and fro.

“What—?” I began, and he glanced up at me, blue eyes wide with startlement at my sudden appearance.

…“Leeches,” I said, professional calm descending by habit over personal tumult. It couldn’t be, I was telling myself, at the same time that I knew it damn well was. “It’s only leeches. They won’t hurt you.” 

“I know what they are!” he said. “Get them off me!” He swatted at his calf, shuddering with dislike. “They’re vile!” 

“Oh, not so terribly vile,” I said, beginning to get a grip on myself. “They have their uses.” 

“I don’t care what use they are!” he bellowed, stamping in frustration. “I hate them, get them off me!” 

“Well, stop whacking at them,” I said sharply. “Sit you down and I’ll take care of it.” 

He hesitated, glaring at me suspiciously, but reluctantly sat down on a rock, thrusting his leech-spattered legs out in front of him. 

“Get them off now!” he demanded.

Anatomy Lesson #65: Anatomy of a Hanging

Greetings anatomy students! Hanging is a ghastly topic, but it has a substantial presence in Outlander and is pertinent to anatomy. So, here we go!

The Oxford Dictionary defines hanging as “specifically to put to death by suspension by the neck.” But, in the past, hanging also meant death by crucifixion or impalement! 

An interesting fact…. The appropriate terminology is the person was hanged, not the person was hung.

Outlander’s first traditional hanging appeared in episode 115, Wentworth Prison; crusty Taran MacQuarrie of the Watch and Jamie Fraser face their ends with stirring gallows’ humor: Jamie is afraid “My wife will never forgive me for getting myself foolishly hung!” Hanged,  Jamie…. the word is hanged!

But, Taran aways knew he was fated to die at the end of a rope – his name is read next.

Jamie’s turn! Scribe, Liam McCallum, recorded Jamie as guilty of “a very extraordinary and abominable crime and most atrocious injury against us!” Snort!

Jamie struggles, but is subdued and resigns himself to this ignoble fate. Such an unworthy end for Laird Broch Tuarach!

Then one of Lucifer’s avenging angels swoops in to spare Jamie for a different fate! But, this outcome awaits another lesson. 

No further traditional  hangings, until season four. Episode 401, America the Beautiful, starts off with a bang… Well, with a hangman’s noose, truth be told.

In a drunken state, Gavin Hayes lay with a marrit woman (psst…Jamie warned him!). When the outraged hubby came at him with a pitchfork, Gavin kicked him down the stairs and now, the hangman’s noose awaits. He should have listened to Mac Dubh! (In Drums of Autumn book, Gavin was guilty of stealing six pounds, ten shillings).

Hayes asks Jamie for two favors: 

#1. Whisky! 

Herself described in Drums of Autumn:

“It was what he asked of me,” he said. “And the best I could manage for him.” 

“Brandy or whisky?” asked Fergus, evaluating Hayes’ appearance with a practiced eye. 

“The man’s a Scot, wee Fergus.” Jamie’s voice was as calm as his face, but I heard the small note of strain in it. “Whisky’s what he wanted.” 

“A wise choice. With luck, he won’t even notice when they hang him,” Fergus muttered

#2. May his last sight be the face of a friend.

Again, from Drums of Autumn: 

If Hayes was still sober enough to see anything, the last thing he saw on earth would be the face of a friend. 

He could see; Hayes glared to and fro as they lifted him into the cart, twisting his neck, desperately looking. 

“Gabhainn! A charaid!” Jamie shouted suddenly. Hayes’ eyes found him at once, and he ceased struggling.

Jamie musters a wan smile for his auld friend and fellow Ardsmuir prisoner.

Drums of Autumn quote continues:

The captain of the guard stood poised, saber raised. 

Suddenly, the condemned man drew himself up straight. Eyes on Jamie, he opened his mouth, as though to speak. 

The saber flashed in the morning sun, and the drums stopped, with a final thunk! I looked at Jamie; he was white to the lips, eyes fixed wide. From the corner of my eye, I could see the twitching rope, and the faint, reflexive jerk of the dangling sack of clothes. A sharp stink of urine and feces struck…

The rope drops. Hayes death appears mercifully quick! Again from Drums of Autumn: 

The hangman had known his business; there had been no undignified struggle, no staring eyes, no protruding tongue; Gavin’s small round head tilted sharply to the side, neck grotesquely stretched but cleanly broken. 

OK, but, what about non-traditional hangings? Any of these in Outlander. But, of course!

Two Jacobite traitors hang from crossed stakes courtesy of Red Coats in Outlander episode 105, Rent. Dougal and his party find the dead men with “T” for traitor carved into their flesh.  Although we don’t know how they died one can reasonably consider this a variation of a crucifixion hanging.

And, finally! In ep 402, Do No Harm, Jocasta’s slave, Rufus, dangles from a hook thrust under his ribs. This type of hanging is known as impalement.

From Drums of Autumn:

From everything I could sense and feel, I thought that the curve of the hook had gone upward through the liver. Likely the right kidney was damaged, and the jejunum or gallbladder might be nicked—but none of those would kill him immediately. 

So, one may reasonably conclude that Outlander has dutifully presented both traditional and non-traditional hangings!

Now, on to anatomy! Waaay back, Anatomy Lesson #12, Claire’s Neck or The Ivory Tower,  has a section on hanging but today we go deeper into the subject.

So, what does hanging have to do with human anatomy? Quite a lot actually, because hanging destroys normal anatomy. Let’s see how. 

Understanding traumatic events from hanging requires a bit of neck anatomy.  So….

Neck Anatomy: The neck is complex because it contains a mess of structures. These include:

    • pharynx for food and air passage
    • larynx for air passage and vocalization
    • trachea for air passage
    • esophagus for food passage
    • common carotid arteries supply blood to head
    • jugular veins drain blood from head
    • cervical vertebrae for support
    • hyoid bone for speech, swallowing, tongue movements
    • cervical spinal nerves, for neck and upper limb innervation
    • muscles for movement of head, neck, scapula and clavicle

Hangings typically traumatize one or more of these neck structures:

    • cervical vertebrae
    • hyoid bone
    • carotid arteries 
    • jugular veins
    • trachea and larynx

Cervical Vertebrae: The neck contains seven cervical vertebrae numbered from skull downward as C1-C7 (Image A). C1 is also known as the atlas; C2 is the axis.

Cervical vertebrae are smaller and more delicate than thoracic and lumbar vertebrae; this is especially true of C1 and C2. Collectively, all seven cervical vertebrae form the cervical skeleton and are bound together by strong ligaments.

Hyoid Bone: The hyoid bone and cervical vertebrae are the only bones in the neck . The U-shaped hyoid (Image B, red) is unusual because it is the only bone of the body that does NOT articulate with other bones. Rather, it is suspended in the neck via muscles and ligaments connecting to neighboring bones and cartilages. More detail on hyoid and cervical vertebrae in Anatomy Lesson #12, Claire’s Neck – The Ivory tower.

Try This: You can palpate your own hyoid bone. Hold chin parallel to floor. Place thumb and forefinger of one hand on either side of your larynx (voice box). Move fingers upward until just under mandible. Squeeze gently, then swallow. You will feel a thin hard structure on each side, the R and L arms of the hyoid.

And, for book readers, Diana wrote about the hyoid bone in Written in My Own Heart’s Blood.

Image B

Common Carotid Arteries: The neck has a R and a L common carotid artery; each is a primary or secondary branch of the aorta arch (Image C).  Common carotids straddle trachea and larynx (Image C -blue/green structures) before splitting into internal and external carotid arteries which supply blood to neck and head.

Image C

Jugular Veins: The neck has two jugular veins on each side; external and internal jugulars. These drain blood from head and neck structures toward the heart Image D).

Image D

Trachea and Larynx: All of larynx plus upper trachea lie in the neck. Both are conduits for air to reach the lungs during inhalation and to leave the lungs during exhalation. In addition, the larynx produces vocalizations. Trachea and larynx provide the only normal route by which air can move to and from the lungs. Of course, a tracheotomy is an exception, but it is also not normal. (Psst…No S5 spoilers from  book readers, please!)

Image E shows trachea and larynx. Tracheal wall is stiff due to cartilage plates. The complex larynx consists of nine cartilages of various shapes and sizes. Learn more about the larynx in Anatomy Lesson #42, “The Voice – No, not that One!”

Now, for some info about hanging. 

Hanging: One might think hanging is a rather simple act, but it is not. There are many types of hanging although death is typically from either strangulation or neck fracture. Here are three common types of hanging.

*Short Drop: A condemned person is placed on a stool, ladder, cart, horse, etc. with noose around the neck. The object is removed leaving the person dangling from the rope. Although the person is unconscious within 15 seconds, death usually takes 10-20 minutes as the noose tightens causing slow strangulation.

*Standard Drop: A condemned person drops 4-6 feet (1.2-1.8m). This is considered more “humane” than short drop because it typically fractures the neck which traumatizes spinal cord and causes immediate unconsciousness and rapid brain death. 

*Long Drop: Drop varies. Height and weight of the condemned were used to calculate the drop needed to fracture the neck, preferably at C2, the axis. This is known as a hangman’s fracture.

Yes, I know! Horrifying to think about, but charts were developed to augment a swift death, the preferred outcome.

Submental Knot: Submental means “under the chin.”  Careful placement of the eye or knot of the noose under the chin jerks the head backward, contributing to neck fracture. Side and back knots tend to strangle rather than fracture the neck.

For more information about the chin, read Anatomy Lesson #26, Jamie’s Chin – Manly Mentus.

Back to Outlander: So, with knowledge about vulnerable neck structures and types of hangings plus their effect on anatomy, let’s review Outlander hangings. 

What about Taran from ep 115, Wentworth Prison? Taran was pushed off a not-very-tall scaffold – so in effect a short drop. Sadly, it didn’t break his neck and the Watchman kicked and struggled at the end of the noose! A member of the execution squad pulled down on his legs to break his neck, an act that was often required to end the misery. Of course, Jamie and other condemned prisoners witnessed this horror!

And, then there’s Hayes. Although his end was swift in Drums of Autumn book, not so in the episode. He did experience either a standard or long drop but afterward, his face is red and bloated and his eyes bloodshot. These findings are more consistent with strangulation than neck fracture, meaning his jugular veins were obstructed leading to death by brain edema and ischemia, wherein:

    • Face becomes engorged with blood
    • Facial skin turns red
    • Facial skin exhibits tiny petechiae/petechia (small blood marks)
    • Bleeding in conjunctiva overlying whites of eyeball (subconjunctival hemorrhage)

So the FX were very good but not well-matched for this type of hanging.

Just so we know, if the deeper lying common carotid arteries are occluded by strangulation, the face appears pale or white.

And, sphincters do relax spontaneously so urine and feces are evacuated. Thankfully, these weren’t part of the FX scheme! 😱

And poor Rufus! Impalement by hook is a very old punishment occurring in Babylonia! Later, it was used in 18th-century Ottoman-controlled Bosnia and by Dutch overlords in Suriname (South America) who impaled troublesome slaves under the ribs.

An 18th century observer recorded that an impaled person could hang as long as three days before expiring. The primary source of pain was extreme thirst.  Thankfully, this type of hanging has been pretty much abandoned.

As for the hyoid bone…. It fractures in about a quarter of hangings but is not the cause of death. Forensic scientists look for a fractured hyoid in suspected homicides because about 50% of hyoids fracture with manual choking.

Fracturing the hyoid bone depends on applied force, age of victim, nature of instrument (ligature vs. hands) so even if the bone is not fractured, a murder is still possible (Image F –  red arrow).

Today, we can be grateful that many countries have abandoned hanging as a means of punishment. An excellent film is available on this topic: Pierrepoint: The Last Hangman. Bonus! Tobias Menzies plays Lieutenant Llewelyn!

In Jamie’s time, hanging was an ignoble death. Why, we might ask? Here is one reasonable thought:

“The sword connoted an honourable way of dying, and an honourable return to the earth, but the rope left the body hanging between heaven and earth and was therefore an unseemly death.” 

Ron Brown, The Art of Suicide

Until next time….Hang in there!

Fun Fact: Mandible

Anatomy Def: The lower jaw or jawbone

Outlander Def: That glorious, heartfelt moment when Jamie’s fingers tenderly graze Bree’s jaw.

Learn about the mandible in Anatomy Lesson #26, Jamie’s Chin – Manly Mentus.

The mandible is the largest, strongest and lowest bone of the human face. In the best scenario, it anchors 16 lower teeth (or fewer if the scenario is not that great). <g> Ignoring three tiny ossicles of each middle ear, the mandible is the only movable bone in the adult human skull.

The mandible has U-shaped body which begins center-front at the chin. The body extends backwards on each side to end at right and left angles. The mandible then juts upward from each angle as hearty slabs of bone, the right and left rami (pl.).  Each ramus ends in a head which articulates with each temporal bone at the temporomandibular joint (TMJ).

During fetal life, the mandible consists of right and left halves but these fuse into a single bone about the second year after birth. A vertical bony ridge (mandibular symphysis) in the midline is evidence of this union.

About 20% of all facial injuries include a fracture of the mandible which is often accompanied by a “twin fracture” on the opposite side.  Metal plates are often used to secure the bony bits during healing.

Try This: Find the point of your chin (mentus).  Now place fingers between chin and lower lip. Move fingers back and forth. Feel the bony ridge? This is the mandubular symphysis  where two mandibular bones fused early in life. Now, run fingers back along one edge of your jaw to a bony knob just below the ear; this is the angle of the mandible.  Now, move fingers upwards along the back of the angle and feel a thick ridge of bone; this is the mandibular ramus. The mandible has an angle and a ramus on each side. Good work, students!

Fun Facts: 

  • This year marks the 44th anniversary of Stephen Spielberg’s film, Jaws!!! 😳
  • The mandible of a blue whale may reach 80 ft. (24 m.) in length!
  • Some indigenous Americans once made weapons from elk, bear, buffalo and horse mandibles.
  • The quijada or charrasgais is a traditional Latin American percussion instrument made from the jawbone of a mule, horse, or donkey.
  • Winston Churchill is credited with the observation: “To jaw-jaw always is better than to war-war.” In other words, a meeting of the minds is preferable to a crushing of the bodies.

Read about the mandible in Diana’s 4th tome, Drums of Autumn. This from the heart-rending first meeting between Jamie and his grown daughter, Brianna.

“Och, no, lassie!” he exclaimed. “I didna mean it that way, at all! It’s only—” He broke off, staring at her in fascination. His hand lifted, as though despite himself, and traced the air, outlining her cheek, her jaw and neck and shoulder, afraid to touch her directly…. 

He did touch her then, his fingers drawing lightly down her face, brushing back the waves of ruddy hair from temple and ear, tracing the delicate line of her jaw. She shivered again, though his touch was noticeably warm; she could feel the heat of his palm against her cheek.

See Jamie tenderly brush Bree’s jaw in Starz ep. 409, The Birds and The Bees. Sob!!!
