Muscles and Fasciæ of the Hand 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. Volar Carpal Ligament
(ligamentum carpi volare).The volar carpal ligament is the
thickened band of antibrachial fascia which extends from the
radius to the ulna over the Flexor tendons as they enter the
wrist. Transverse Carpal Ligament (ligamentum carpi transversum;
anterior annular ligament) (Figs. 421,422).The transverse carpal
ligament is a strong, fibrous band, which arches over the
carpus, converting the deep groove on the front of the carpal
bones into a tunnel, through which the Flexor tendons of the
digits and the median nerve pass. It is attached, medially, to
the pisiform and the hamulus of the
