Anatomy def: Brachialis is a muscle of the upper arm; covering lower half of humerus (upper arm bone) and ending on ulna (forearm bone), it flexes (bends) the elbow joint.
Outlander def: Brachialis, part and parcel of the big, beautiful bulge on Jamie’s right arm. The Highland Hero’s eye scans the sky for stormy weather. It’s gonna be a bad one – best batten down the hatches!

Contrary to popular opinion, biceps is NOT the most powerful flexor of the elbow joint. This honor goes to – drum roll – brachialis! Believe it or not, brachialis generates roughly 50% more power than biceps during elbow flexion. Truth!
Puir brachialis, lying deep and over shadowed by the honking biceps, it doesn’t get its fair share of attention from muscle builders or Outlander lovers.
Read about arm muscles in Voyager book. Couldn’t find a quote for Jamie, but there is a splendid one of Claire as she assess her assets, <G> before venturing through the stones once more. Just try to remember —brachialis, that step-sister deep to biceps, performs MOST of the work during elbow flexion!
Dropping the towel, I looked myself over. Flexed my arms, raised them overhead, checking for bagginess. None; biceps and triceps all nicely defined, deltoids neatly rounded and sloping into the high curve of the pectoralis major. I turned slightly to one side, tensing and relaxing my abdominals—obliques in decent tone, the rectus abdominis flattening almost to concavity.
