Document Summary

Anatomy 9501: lower limb l9 arches and intrinsic foot muscles. Calcaneus: ant. transverse arch (a to b, lateral longitudinal arch (b to c, medial longitudinal arch (a to c) This is based on several things : shape of bones, supporting ligaments. Flexor hallucis brevis, adductor hallucis, flexor digiti minimi brevis. The tibial nerve splits after they pass behind the med. malleolus into the med. and lat. plantar nerves. Attachments: calcaneal tuberosity to lat. base of 5th prox. Attachments: calcaneal tuberosity to plantar surface of middle phalanyx of toes 2-5. The tendon forks and goes to both the med. and lat. side. Attachments: calcaneal tuberosity to med. base of the 1st proximal phalange. Attachments: body of calcaneous (2 heads) to the tendon of fdl. Attachments: tendons of fdl to med. aspect of proximal phalange and dorsal expansion. Nerve: 1 (digit 2) = med. plantar n. , 2-4 (digits 3,4,5) = lat. plantar n.
