no ANATOMY OF THE DOMESTIC FOWL 



Origin. — From the shaft of the mid-metacarpal bone, just below 

 the pollex. 



Insertion. — Distal apex of the poUex. 



Shape. — Short, small, fleshy. 



Relations. — Superiorly, with the inferior part of the pollex. 



Action. — Flexes the pollex. 



Flexor Minimi Digiti. Location. — Inferior side of the metacarpus. 



Origin^- — From the posterior part of the median metacarpal close 

 to the OS carpi ulnare. A few fibers extend to the ulna. 



Insertion. — Into the base of the median phalanx. 



Shape. — Small, slender, short. 



Relations. — Superiorly, with the metacarpal bone. 



Action. — ^A flexor of the digit. 



Flexor Minimi Digiti Brevis (Fig. 13, No. 30). Location. — In- 

 ferior to the third, or small finger. 



Origin. — From the lower and posterior end of the median meta- 

 carpal and from the adjacent tendon of the preceding. 



Insertion. — Inserted to the apex of the small. finger. 



Shape. — Small and rather rudimentary. 



Relations. — Inferior to the smaU finger. 



Action. — ^Acts as a posterior Hgament of this joint. 



Abductor Minimi Digiti. Location. — Supero-lateral side of the 

 small finger. 



Origin. — From the proximal extremity of the anterior aspect of the 

 third finger. 



Insertion. — To the posterior border of the proximal phalanx of 

 the second, or index-finger at a point just a,bove the tip of the third 

 finger. 



Shape. — ^A few muscular fibers with some tendinous material. 



Relations. — At the base of the median segment of the index-finger 

 and to the side of the third. 



Action. — ^Antagonizes the powerful flexors on the back oi the 

 joint. 



Interosseus Dorsalis (Fig. 13, No. 31). Location. — By the side 

 of the metacarpus. 



Origin. — From the margin of the shaft of the median metacarpal. 



Insertion. — To the anterior part of the base of the distal phalanx 

 of the index digit. ■ ' 



Shape.— rShoxt, deUcate, with long tendon. 



Relations.— Initzns&y, the metacarpal bone.
