The muscles of the hand are principally concerned, as regards surface form, in producing the thenar and hypothenar eminences, and cannot be individually distinguished; the thenar eminence, on the radial side, is larger and rounder than the hypothenar, which is a long narrow elevation along the ulnar side of the palm.
They drain into a venous plexus which is situated over the thenar and hypothenar eminences and across the front of the wrist.
The muscles of the hand are subdivided into three groups: (1) those of the thumb, which occupy the radial side and produce the thenar eminence; (2) those of the little finger, which occupy the ulnar side and give rise to the hypothenar eminence; (3) those in the middle of the palm and between the metacarpal bones.
When the Palmaris brevis is in action it produces a wrinkling of the skin over the hypothenar eminence and a dimple on the ulnar border.
Wasting of the thenar and hypothenar eminences, and filling up of the hollows above and below the anterior annular ligament, render the appearance on the palmar aspect characteristic.
While an assistant draws up the skin as much as possible, the surgeon makes an accurate circular incision through the skin, about an inch below the styloid processes, just grazing the thenar and hypothenar eminences.
