Document Summary

Big toe is medial while the thumb is lateral. Flexors are plantar, extensors are dorsal the axis of the foot is the second digit, not the middle. Attachments of interossei and innervation of lumbricals reflect this change. Medial and lateral plantar nerves are homologues of the median and ulnar nerves respectively. Composed of skin, aponeurosis, four layers of muscles, tendons, three ligaments. Similar to the palmar aponeurosis of hand. Stronger and thicker and supports the arches of the foot runs subcutaneously from the calcaneus and inserts via slips of tendons at each toe. Abductor hallucis innervated by medial plantar nerve inserts on the proximal phalanx of big toe. Flexor digitorum brevis flat muscle with a wide belly running under the calcaneus, navicular and cuboid. Provides tendons to the lateral four toes that insert on the. Provides tendons to the lateral four toes that insert on the middle phalanges.
