190 SPECIAL ANATOMY. 



b. Extended by ; extensores carpi radiates and ulnaris. 



c. Adducted, that is, moved towards the ulnar border of the 

 arm by : flex, and extern, carpi ulnaris ; abducted (towards the 

 radial border) by : extens. and flexor radiales carpi ; Proned 

 and supined, see D. 



421. F. The fingers are : 



a. Flexed by : flexor digitor. (sublimis second phalanx of the 

 second, third fourth, and fifth fingers) ; by flexor digitor. pro- 



fundus (third phalanx of the same fingers; by lumbricales (first 

 phalanx of the same fingers) ; first phalanx of thumb, by flexor 

 pollicis brevis, second phalanx by^/7. poll, longus; of little finger, 

 by^?. digiti minimi. 



b. Extended by : extens. comm. (second, third, fourth, and 

 fifth fingers) ; the thumb by : extens. pollic. long., brevis and 

 abductor longus ; the index finger by : extens. indicis ; the fifth 

 finger by : extens. dig. minimi propr. 



c. Adducted (towards the middle finger) by: interossei and 

 adduct. pollicis. 



d. Abducted by : interossei, abduct, pollic. and digiti minimi. 



e. The thumb and little finger approximated by: opponens 

 pollic. and digit, min., whereby the hand is made hollow. 



422. IV. Inferior Extremity. 

 A. The thigh is : 



a. Flexed by : psoas and iliacus [and pectineus"]. 



b. Extended and abducted by : glutsei (3).

 quadratus femoris.

 part of glutseus med. and minimus.
