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
Anatomical terms of muscle need antagonistic pairs located in opposite sides of a joint or bone, including abductor-adductor pairs and flexor-extensor pairs. These consist of an extensor muscle, which "opens" the joint (by increasing the angle between the two bones) and a flexor muscle, which does the opposite by decreasing the angle between two bones. However muscles don't always work this way - sometimes agonists and antagonists contract at the same time to produce force, as per Lombard's paradox. Also, sometimes during a joint action controlled by an agonist muscle (see above definition of agonist), the antagonist will be slightly activated, naturally. This occurs
