Mini Anatomy Lesson: Corrugator Supercilii

 

Anatomy Def: Paired muscles of facial expression.

Outlander Def: Ian’s worry lines when he learns he must leave his beloved Emily! 😢

Don’t know about you, but for me, John Bell’s performance in Outlander episode 604, Hour of the Wolf was flawless. His facial expressions perfectly mirrored the stress roiling in his personal life.

Facial Expression: Humans enjoy 22 pair of muscles controlling facial expression, more than any other animal, blessing us with an amazing range of emotional aspects. 

As Ian hears the Mohawk’s decision about his and Emily’s fates, the skin wrinkles between his eyebrows. How does this happen?

Corrugator Supercilii: Well, his facial expression is caused by contraction of corrugator supercilii (CS) muscles, just one of the 22 pair! 😲

Super silly, huh? 😜

Meaning: Actually, this pair of muscles is so named because of their action and also by their placement in the face: 

    • Latin, con meaning “together” + rugare “wrinkle”
    • Latin, super meaning “over” + cilium ”eyebrow” 

Ergo, corrugator supercilii wrinkle the skin between the eyebrows.

Violà! 🤗

Anatomy: The figure below is a computer generated image of the paired CS shown as green slashes. CS originate from the forehead (frontal bone) about midway along each eyebrow and insert into the skin at the top of the nose (nasion). 

Function: As CS contract, the eyebrows are drawn together and downward, producing vertical wrinkles of the forehead skin.

Emotional Signal: CS belong to a group of frowning muscles, used to convey suffering! And, who does that better than our beloved Ian? 😢 

Frontalis: Just to complicate matters, let’s throw in a second pair of facial expression muscles – the frontalis. In the image below, frontalis fibers (dark green patches) run vertically through the forehead. They originate from the top of forehead (frontal) bone and insert into the skin above the eyebrows. 

Frontalis muscles raise the eyebrows and wrinkle the forehead skin but this time, the creases run horizontally. Consider Jamie in Outlander episode 606, The World Turned Upside Down. Here, a “worrit” Jamie attends to Malva’s chatter and seductive overtures.

So what happens if CS and frontalis muscles contract simultaneously? Let’s look again at Ian for the answer. Deeply concerned for the wee soul of his stillborn daughter, Iseabaìl, he confides in his beloved uncle! 

Ian contracts CS (red arrow), hence the vertical wrinkles between the brows, and frontalis (blue arrow) producing horizontal wrinkles in his forehead skin. Working together, both sets of muscles truly convey worry, anguish, and despair.   

Learn much more about the muscles of facial expression in my big Anatomy Lesson #11, Jamie’s Face or Ye do it Face to Face?

Lest you think that humans are the only creatures with muscles of facial expression, meet my year-old Vizsla puppy, Finnegan. Check out the wrinkles between his “brows”? 

Studies suggest dogs lack CS muscles but other facial muscles perform a similar function. Such muscles give them what is known as pedomorphic facial features (infant-like). Humans apparently prefer such features in domesticated dogs. 🥰

See Ian’s worry muscles in Outlander Episode 604, Hour of the Wolf.

Read about Ian’s distress in Diana Gabaldon’s sixth big book, A Breath of Snow and Ashes wherein, it is Brianna that comforts Ian:

“Aye, maybe. But …” He closed his eyes, hands clenched hard into fists on his thighs. “Where is she, then?” he whispered, and she could see tears trembling on his lashes. “The others—they were never born; God will have them in His hand. But wee Iseabaìl—she’ll not be in heaven, will she? I canna bear the thought that she—that she might be … lost, somewhere. Wandering.”

“Ian …”

“I hear her, greeting. In the night.” His breath was coming in deep, sobbing gasps. “I canna help, I canna find her!”

“Ian!” The tears were running down her own cheeks. She gripped his wrists fiercely, squeezed as hard as she could. “Ian, listen to me!”

He drew a deep, trembling breath, head bent. Then he nodded, very slightly.

She rose onto her knees and gathered him tight against her, his head cradled on her breasts. Her cheek pressed against the top of his head, his hair warm and springy against her mouth.

“Listen to me,” she said softly. “I had another father. The man who raised me. He’s dead now.” For a long time now, the sense of desolation at his loss had been muted, softened by new love, distracted by new obligations. Now it swept over her, newly fresh, and sharp as a stab wound in its agony. “I know—I know he’s in heaven.”

Was he? Could he be dead and in heaven, if not yet born? And yet he was dead to her, and surely heaven took no heed of time.

She lifted her face toward the cliff, but spoke to neither bones nor God.

“Daddy,” she said, and her voice broke on the word, but she held her cousin hard. “Daddy, I need you.” Her voice sounded small, and pathetically unsure. But there was no other help to be had.

“I need you to find Ian’s little girl,” she said, as firmly as she could, trying to summon her father’s face, to see him there among the shifting leaves at the clifftop. “Find her, please. Hold her in your arms, and make sure that she’s safe. Take—please take care of her.” 

Deep stuff!

The deeply grateful,

Fun Fact: Anatomy of Ian’s Uniform!

Hallo, Outlander fans. Welcome to today’s Fun Fact: Anatomy of Ian’s Uniform! 

This Fun Fact is especially appropriate for Americans as May 16th is  also our national Armed Forces Day!  Pretty timely, no?

If you are like me, you are fascinated with Ian’s uniform in Outlander episode 512, Never My Love, the splendid finale of Season five! In Claire’s dissociative dreamscape, Ian arrives in full dress uniform for Thanksgiving dinner at the Fraser home! 🦃

I wanted to know more about Ian’s uniform, so I turned to Edward Maloney, Lieutenant Colonel, US Army (retired) for assistance. Know that LTC Maloney is also a faithful, long-time fan of Outlander books and show and was more than willing to share his decades-long expertise in this matter.

Just so you know, Colonel Maloney’s former unit is the 101st Airborne Division of the US Army. Below is its beautiful and dramatic Distinctive Unit Insignia which reads “Rendezvous With Destiny!”

Addendum: I just learned “Hang Tough and Currahee!” is the Battle Cry of the 101st Airborne!  Hang tough means “in your parachute harness” and “Currahee” is from the Cherokee word meaning “We stand alone together.” (A good thought for soldiers trained to fight surrounded.)

Thank you, Lieutenant Colonel Maloney, for your service!

 

So, grab a cuppa (or your fav beverage) and let’s learn about the anatomy of Ian’s uniform, courtesy of LTC Maloney!

Ian’s uniform indicates he belongs with the Infantry, the oldest branch of the US Army. When was this branch formed? Turns out, very close to the date  depicted in the Outlander S5 finale! 

On 14 June 1775, the Continental Congress authorized ten companies of riflemen, the first infantrymen.  Nine years later, the First American Regiment was constituted on 3 June 1784 and it was the 3rd Infantry. Currently, well over two hundred years old, clearly the Infantry is a distinguished branch of the US Army!

So, follow the colored arrows in the below images to discern the anatomical features of Ian’s uniform. (psst…The following image appears twice so you don’t have to keep moving up and down to follow the arrows and explanations!)

Let’s get on with the dissection! 😉

Blue Arrow:  A branch insignia on Ian’s L lapel displays two gold crossed muskets, overlying a disk of Saxony Blue. This insignia is unique to infantry and no other branch of the US Army is allowed this distinction.

The crossed muskets are vintage 1795 Springfields, the first official US shoulder arm made in a government arsenal:

    • caliber .69
    • flint lock
    • smooth bore
    • muzzle loader

 

 

Yellow Arrow: Above his L breast, Ian wears a Combat Infantryman’s Badge, unique to those who have served in combat. It is a single flint lock musket on a blue background. 

Green Arrow: Just above Ian’s L breast is a line of Decoration & Award Ribbons, also known as “fruit salad” or “Travel Ribbons.” These are worn in lieu of larger full-size or miniature medals which are awarded for service.  Here, the Ribbon is a line of Ian’s Mohawk beads! 

Gold Arrow:  Over Ian’s L breast is The Maltese Cross with a Bull’s-eye surrounded by a wreath, known as the Expert Marksman Badge. This badge is unique to Army and Marine Corps, although the designs differ. The suspended bars underneath the badge are added for each weapon the soldier qualifies as an expert, such as pistol, rifle, etc. 

White Arrow:  Worn on Ian’s L sleeve, the chevrons signify a soldier’s rank. Two chevrons indicate Corporal, the lowest Noncommissioned Officer Rank (NCO) who leads an infantry fire team. 

Violet Arrow: Ian’s service cap bears the US Coat of Arms. It is backed on a brass disk and in the case of infantrymen, backed by a Saxony Blue disk. 

Khaki Arrow: Ian’s Regimental Coat of Arms is worn above his R breast.  This insignia will indicate his permanent regiment not necessarily the one to which he is currently assigned. 

Tan Arrow: Also worn above his R breast, this insignia indicates a Unit award such as Presidential Unit Citation, Distinguished Unit Citation, etc. 

Next image,  we see Ian’s left shoulder!

Aqua arrow:  Indicates the Distinctive Unit Insignia which is usually a variation of the regiment’s coats of arms but unique to each regiment. This one looks like the 2nd Infantry Regiment but the colors are altered. 

Red Arrow:  L shoulder – Shoulder Sleeve Insignia  indicates the current unit of assignment – Ian serves with a Native American unit, the Mohawk. this insignia was created by Outlander.

And finally, Ian’s infantry blue cord or fourragere (below) is a military decoration worn over the right shoulder of all infantry-qualified US Army soldiers. 

Ian’s fourragere from afar.

And, a closeup. This is Ian’s fourragere in light blue, (dubbed “Infantry Blue” by the US Army), worn under the right shoulder and under the right epaulette of a US Army infantry soldier’s dress uniform jacket.

The cord is composed of a series of alternating left and right half knots that are tied around a leader cord to form a “Solomon bar”.

Fitting that Ian should wear his dress uniform for Thanksgiving, even if that bird is just an illusion!

In summary, Ian’s uniform tells us he is:

    • Infantryman
    • Decorated soldier
    • Served in combat
    • Expert marksman
    • Corporal of an infantry fire team
    • Bears US Coat of Arms for infantrymen on his service cap
    • Wears his permanent regiment’s Coat of Arms
    • Decorated infantryman
    • Member of a distinct infantry unit
    • Member of Native American unit
    • Qualified infantryman

Whew! I don’t know about you, but I am thoroughly impressed with warrior Ian!

And, I am deeply grateful for the men and women who serve in the US Armed Forces.

I could not have done this fun Fact without the aid of LTC Edward Maloney, US Army. Thanks to his expertise for this brief lesson exploring the anatomy of Ian’s US Army insignia!

I hope all Outlander fans, worldwide, will express their gratitude for the warriors who daily protect them, their families, and their homelands. Please take a quiet moment to honor them!

Fun Fact: Incisura

Anatomy Def: Notch between tragus and antitragus of the auricle. To understand the meaning of these words, read on!

Outlander Def: The ear cleft (red arrow) patiently awaiting Claire’s attention!

Learn about incisura in Anatomy Lesson #24  Hear, Here – The Ear! 

The auricle, part of the outer ear, is the visible, bendable flap situated on either side of the head. Like fingerprints or venous patterns on the back of hands, each auricle is unique to its owner.  The auricle has a cartilage core enveloped by thin skin. Auricular (adj.) anatomy is complex; it’s hollows, ridges, and whorls act to modify sounds waves of particular frequencies.

Near the base of the auricle and just above the ear lobe are two wee bumps: tragus is nearest the face; anti-tragus is nearest the outer rim. These bumps are separated by a notch, the incisura. Yay!

Incisura is also known as the intertragic notch.  An apropos name for that tragic moment when young Ian, Jamie’s beloved nephew, chooses to exchange himself for Roger Mac. Ian proves himself “a man of worth!”

Fun Fact: This is one good reason to know about the incisura. The incisura/intertagic notch is the point specified  in the U.S. Army’s regulation governing the length of sideburns in male soldiers. In other words, sideburns cannot be longer than the incisura. Who knew? Male soldiers, I presume! <G>

Try This: Find the notch near the base of your auricle. Insert finger. This is the incisura (intertragic notch), flanked on either side by the cartilaginous bumps, tragus and anti-tragus. Specific function of incisura is not known but likely aids in sound wave modification.

Otalgia: Some people experience incisural pain, generally known as otalgia, meaning “ear pain.” The most common causes of incisural pain are:

    • otitis externa or inflammation of outer ear (auricle/ear canal)
    • otitis media or inflammation of middle ear (between ear drum and inner ear)

Read about the auricle in Diana’s splendid big book, The fiery Cross. Many ear quotes to choose from, but in this one, Jamie’s wandering thumb comes verra close to Claire’s incisura! (cough, cough)

His fingers went under the mass of hair, and I felt his hand cup the base of my skull, holding my head like a chalice. 

“I saw my mother in her coffin,” he said at last. His thumb touched my ear, drew down the curve of helix and lobule, and I shivered at his touch. 

“The women had plaited her hair, to be seemly, but my father wouldna have it. I heard him. He didna shout, though, he was verra quiet… He undid her plaits and he spread out her hair in his two hands across the pillow…”

Sob!

See Jamie’s left incisura as he sadly ponders Ian’s decision to remain with the Mohawk in Starz Outlander episode 413, A Man of Worth!
