Fun Fact: Supercilium

Anatomy Def: Supercilium: An eyebrow, the arch of hair above each eye.

Outlander Def: Murtaugh’s Bodacious Brows! Supersilly, huh? 😜

Learn about supercilium in Anatomy Lesson #29, The Eyes Have It! 

The eyebrow or supercilium (pl. supercilia), is a linear growth of coarse hair above the eyelashes. Generally, eyebrows mimic the shape of brow ridges of the underlying (frontal) bone.

Try this: Prove it for yourself. Slowly run your fingers over the ridge of bone above each eye socket. Likely, most of your eyebrow tracks along this bony landmark. Sometimes, the eyebrow tail will deviate (up or down) as the brow ridge disappears.

Like hair of scalp, eyelashes, beard, and nether regions, brow hair is deeply embedded in the dermis of skin, a feature clearly demonstrable when viewed in a light microscope.

This deep placement of hair is very different than, let’s say, the eyelid wherein fine hairs barely reach the surface of the skin and no further – we don’t really see them. These very fine, small hairs are known as vellus hair. Eyelashes of the eyelids are different, as mentioned above.

Further, some skin regions such as lips, palms, soles of feet, nipples, and parts of the genitalia lack any hair as it would interfere with tactile sensation in these regions.

Ever wonder what eyebrows are for? We don’t actually know but here are a few theories to ponder:

  • Wicks moisture (sweat or rain) away from eyes (Herophilos, 335-280 B.C.E.)
  • Helps protect eyes from offending objects
  • Scared predators once early hominids started sleeping on ground? 🤨

Recently, a meritorious theory has emerged that human eyebrows serve primarily as a means of communication. After we developed smooth foreheads, visible, hairy eyebrows enhanced our range of non-verbal emotions, such as concern, annoyance, anger, recognition, and sympathy.

Don’t believe it? Just take another gander at Murty’s Splendid Supercilia. These Luscious Laddies enjoy a vigorous life of their own! 😂😂😂

Fun Fact: For centuries and across many cultures, people have modified eyebrows by shaving, plucking, makeup, and ornamentation.  This has been going on for a very looong time. Yep, it isna just us! 😉

Read about Murty’s Fabulous Furries in Outlander book! As early as Chapter 3, Herself conjures a remarkable mental image of Murtaugh’s facial characteristics, including his supercilia!

“I found myself staring into a pair of sharp black eyes…

And who the hell are you?” I said in astonishment. My rescuer, if I cared to call him that, was some inches shorter than I and sparely built, but the bare arms protruding from the ragged shirt were knotted with muscle and his whole frame gave the impression of being made of some resilient material such as bedsprings. No beauty, either, with a pockmarked skin, low brow, and narrow jaw…

The swarthy little man shrugged. “At the foot o’ Craigh na Dun. She was havin’ words with a certain captain of dragoons wi’ whom I chanced to be acquent’,” he added, with a significant lift of his eyebrows. “There seemed to be some question as to whether the lady was or was not a whore.”

Bedsprings? 😂

Whore? 😲

Fun Fact: Glabella

Anatomy Def: Smooth part of the forehead between the eyebrows and above the nose.

Outlander Def: Marsali’s smooth and confident brow supports her beloved Fergus as he plans Murtagh’s escape!

Learn about the glabella in Anatomy Lesson # 11, “Jamie’s Face” or “Ye do it Face to Face?”

When we are restful and relaxed, glabellar (adj.) skin  is smooth. When we are anxious, worried, appalled or plagued by other strong emotion, glabellar skin may wrinkle.  A pair of small muscles deep to the glabellar skin contract to produce the wrinkling. Perhaps you recall a previous fun fact about corrugator supercilii. No? Well, no mind, this is the name of the wee muscles that wrinkle the glabellar skin.

Those who develop permanent wrinkles of the glabellar skin can opt for Botox injections which paralyze corrugator supercilii (and others) to produce a more comely smooth brow.

The glabella isn’t just for beauty, it is also used in diagnosing certain neurological conditions. Repetitive tapping on the glabella elicits the Glabellar reflex or Glabellar tap sign, a reflex wherein subjects blink in response to the first several taps. If the blinking persists, the response is deemed abnormal.

Fun Fact: In cases of dehydration, the skin of the glabella can be gently lifted and pinched to measure skin turgor. A dehydrated patient’s glabellar skin tends to remain “tented” rather than resume its normal flat state.

Read about the smooth skin of the brow in Drums of Autumn. Here, Ian paints Claire’s face with mud after the manner of his indigenous friends. As his finger passes between her eyebrows, the mud is spread over the glabella:

Ian hadn’t waited for the results of my dithering. He stooped and scraped up a small clot of earth, spat in it and stirred it to mud. Without comment, he dipped his forefinger into the puddle, and drew  a line from my forehead down the bridge of my nose.

“Ian!” 

“Shh,” he murmured, frowning in concentration. “Like this, I think.” He added two lines across each cheekbone, and a rough zigzag down the left side of my jawbone. 

See Marsali’s smooth glabella as she attends Fergus, watching him plan the jail break in Outlander ep 412, Providence. Go get ’em Fergus and Marsali!
