ep-106-latissimus-dorsi
Anatomy def: Broadest pair of back muscles, extending from lower spinal vertebrae to each humerus. Latissimi dorsi extend the humeri (pl.) as in pull-ups but also adduct (pull against torso) and internally rotate (roll towards sternum) these bones. Commonly known as “lats,” at the gym.

Outlander def: Substantial Jamie “lats” strain against ghastly iron manacles as they anticipate the lead pummels!

Learn about latissimi dorsi and the movements each exerts on its respective humerus in Anatomy Lesson #19, “To Arms, Too Arms, Two Arms!”

Read about Jamie’s back muscles in Dragonfly in Amber book. Herself writes about back muscles fairly often (yay!). Somewhere, amid these back muscles are the latissimus dorsi!

Jamie had by now thrown himself on the floor and was doing the Royal Air Force exercises I had recommended to strengthen the muscles of his back.

He was gentle and slow, pausing now and then to kiss me deeply, moving again only at my silent urging. I ran my hands softly down the slope of his back, careful not to press on the healing ridges of the fresh scars.

I touched each soft hollow, the hidden places of his body. Felt the grace and the strength of each curving bone, the marvel of his firm-knit muscles, drawn lean and flexible across the span of his shoulders, smooth and solid down the length of his back…

See Jamie’s left latissimus dorsi (red arrows) bulge at Fort William’s whipping post (Starz, episode 106, The Garrison Commander). If only he could smack that madman in the mouth… Ahhhh, wait a wee bit Jamie, this will come to pass soon!

A deeply grateful,
