Abductor hallucis muscle the base of the first proximal phalanx and its related sesamoid bone. Its medial surface is superficial and covered with the muscle's fascia and the skin. Abductor hallucis is innervated by the medial plantar nerve. The nerves that supply it enter the muscle from its upper border. The deep tendon reflex of the abductor hallucis. was first described and demonstrated by Dr. M. W. Spanakos. Abductor hallucis muscle The abductor hallucis muscle is an intrinsic muscle of the foot. It participates in the abduction and flexion of the great toe. The abductor hallucis muscle is located in the medial border
Fourth metatarsal bone on the lateral side a single facet, for articulation with the fifth metatarsal. The head or anterior extremity articulates with the fourth proximal phalanx, the first bone in the fourth toe. The third and fourth dorsal interossei muscles attaches to the fourth metatarsal bone. The third dorsal interossei from the medial side of the bone and the fourth dorsal interossei from the lateral side. The function of the muscle is to spread the toes. The second Plantar interossei muscle originates from the medial side of the base and shaft of the fourth metatarsal. The function of the muscle is to
