These are three in number. 1. Palmaris Magnus, Flexor carpi radialis, Radialis internus, (F.) Epitrochlo-metacarpien (Ch.), Palmaire grand, Radial auterieur. A long fusiform muscle, which passes obliquely from the inner tuberosity of the humerus to the upper extremity of the second metacarpal bone. It bends the hand. 2. Palmaris longus, Latescentis chordaa, Ulnaris gracilis, (F.) Epitrochlo- carpi-palmaire (Ch.), Palmaire long, P. grele. This muscle is situate on the inner side of the last. It is very slender, and passes from the inner tuberosity of the humerus to the anterior annular ligament of the carpus, and to the palmar aponeurosis, which it seems to form by the vanishing of its fibres. It stretches the palmar aponeurosis, and bends the hand. 3. Palmaris Brevis, Cara quadrata, Carpioeus, (F.) Palmaire cutane. A small, thin, quadrilateral muscle; situate before the thenar eminence. It passes from the annular ligament of the carpus to the integuments of the palm of the hand, which it wrinkles by its contraction.
