Flexor Digiti Minimi Brevis (Foot)

The flexor digiti minimi brevis is an intrinsic muscle located in the third layer of the plantar muscles of the foot. It plays a crucial role in the movement of the little toe.

This muscle originates from the base of the fifth metatarsal and inserts at the base of the proximal phalanx of the fifth digit. These attachments facilitate its function in toe movement.

The main action of the flexor digiti minimi brevis is to flex the little toe at the metatarsophalangeal joint. This movement is essential for proper foot function and balance.

The flexor digiti minimi brevis is innervated by the superficial branch of the lateral plantar nerve. This nerve supply is vital for muscle contraction and movement.

The blood supply to the flexor digiti minimi brevis comes from branches of the anterior and posterior tibial arteries. Adequate blood flow is important for muscle health and function.
