MUSCLE TISSUE 



FIG. 68 



Superficial muscles of front of right 

 forearm. (Testut.) 



forming a short muscular 

 belly ending in a slender 

 tendon, inserted into the 

 palmar fascia, and sends 

 a slip to the abductor 

 pollicis, sometimes one to 

 the little finger muscle. 



Flexor carpi charts (M. 

 ulnaris interims) is the 

 innermost of the super- 

 ficial group; arises by two 

 heads, one from the com- 

 mon tendon, and one from 

 the inner side of the olec- 

 ranon and upper two- 

 thirds of the posterior 

 border of the ulna by an 

 aponeurosis common to it, 

 the flexor profundus digi- 

 torum and the extensor 

 carpi ulnaris; muscular 

 fibers end in a tendon 

 which occupies the ante- 

 rior margin of the lower 

 half of the muscle; pos- 

 teriorly the muscular fibers 

 continue down to within 

 an inch of its insertion; 

 inserted into the pisiform 

 by a small band to the 

 anterior annular ligament. 



Flexor sublimis digi- 

 torum, placed behind the 

 preceding, arises by three 

 heads: (1) Inner condyle 

 by the common tendon, 

 fibrous septa, and internal 

 lateral ligament; (2) inter- 

 nal margin of the coronoid ;
