Back 1

4 Layers; 1 is the most superifical. THese muscles arise from tarsals or metatarsals and are inserted into the phalanges

Front 2

Superifical to all these layers of muscle is what?

Back 2

A strong layer of CT known as a plantar aponeurosis that supports the muscles and helps in maintaining the longitudinal arches

Front 3

-DOrsal muscles abduct the toes from the axis of the foot; which is the 2nd toe

Front 7

what is the tarsal tunnel?

Back 7

bony groove behind the medial mallolus bridged by a layer of dense ct (flexor retinaculum)
-passage for tendons of flexor muscles in deep layer of posterior compatment of leg
-post tibial vessel and tibilal nerve
-

Front 8

Back 8

Continues to dorsal aspect where it changes its name to the dorsalis pedis artery; the superifical peroneal nerve supplies the skin of the dorsaum of the foot

Front 9

WHat does the post tib artery do in the foot?

Back 9

Divides into two branches
medial and lateral plantar arteries
-THese distirbute in the plantar region of the foot
-Tibial nerve supplies muscles and the skin of sole of the foot
