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
Bone mineral of the hydroxyapatite. Bone mineral is dynamic in living animals; it is continually being resorbed and built anew in the bone remodeling process. In fact, the bones function as a bank or storehouse in which calcium can be continually withdrawn for use or deposited for storage, as dictated by homeostasis, which maintains the concentration of calcium ions in the blood serum within a particular range despite the variability of muscle tissue metabolism. Parathormone and calcitonin are the principal hormones with which the neuroendocrine system controls this ongoing process. The parathyroid and thyroid glands in the neck produce those hormones; thus,
