THE MEDIAL VOLAR MUSCLES 



463 



The Palmaris brevis is a thin, quadrilateral muscle, placed beneath the integu- 

 ment of the ulnar side of the hand. It arises by tendinous fasciculi from the 

 transverse carpal ligament and palmar aponeurosis; the fleshy fibers are inserted 

 into the skin on the ulnar border of the palm of the hand. 



The Abductor digit! quinti (Abductor minimi digiti) is situated on the ulnar 

 border of the palm of the hand. It arises from the pisiform bone and from the 

 tendon of the Flexor carpi ulnaris, and ends in a flat tendon, which divides into two 

 slips ; one is inserted into the ulnar side of the base of the first phalanx of the little 

 finger; the other into the ulnar border of the aponeurosis of the Extensor digiti 

 quinti proprius.
