 the right palm 



(2'i layer). 



(The mm. abductor pollicis 

 brevis, abductor digiti V and 

 flexor digiti V brevis have been 

 removed; a piece has been cut 

 out of the tendons of the m. 

 flexor digitorum sublimis.) 



Mm. lumbricales 



narrow muscles, 

 the palm between the tendons 

 of the m. flexor digitorum pro- 

 fundus. Origin: two radial 

 from the radial side of the cor- 

 responding tendons, two ulnar 

 each from two adjacent tendons 

 of the m. flexor digitorum pro- 

 fundus. Insertion: the flbers converge to form narrow tendons which run on the radial si4^' 

 of the 2"'! 5'li finger, volarward from the lig. capitulorum transversum (see Fig. 241), to the 

 posterior surface of the first phalanx and to the triangular expansions of the ti'nduns u^f tji:fn.i5" 

 tensor digitorum communis (see Fig. 361). The tendon of the third muscle is frequentiv ."^^iK'cd 

 and sends also a process to the ulnar margin of the Si'^^ finger. Action: tbev flex ^^--^ first and 

 extend the second and third phalanx of the 2'l 5*^ finger. Innervation. "2( 3) radial from 

 the n. medianus, 2( 1) ulnar from the ramus profundus of the ramus v^Iari.^t nianus u. ulnaris.
