Dorsum.—The extensortendons are plainly seen. Theradial artery may be felt in theanatomic snuff-box (betweentwo of the extensors of thethumb as it winds around thefirst metacarpal bone to reachthe deep palm) (Fig. 212). The long flexor and extensortendons of the fingers may beplainly felt and seen at the Deep branch Posteriorinterosseous Fig. 213.—The Arm and Forearm,Posterior.

THE LEG. 307 The femoral artery, femoral vein, 2ind femoral nerve pass under theligament, the artery lying on the psoas muscle. Their order fromthe medial side outward is V-ein, A-rtery, N-erve. From the hip down, the anterior surface is al-ternately j?exor and extensor The posterior surface is exactly the reverse. Flexor for for for for toes. Extensor for for for for toes. Thigh.—Anterior and sides of the femur are covered by thequadriceps muscle, which extends the knee. The sartorius musclecrosses from the anterior spine of the ilium to the middle of themedial side of the thigh and down to the tibia, and when it contractsit makes a depression rather than an el
