Hallucis muscle

Hallucis Muscle

The hallucis muscle, as illustrated in Gray's Anatomy.

The hallucis muscle is a muscle of the human body, specifically located in the foot. It is involved in the movement of the big toe, and is divided into two parts: the flexor hallucis longus muscle and the flexor hallucis brevis muscle.

Structure

The hallucis muscle is located on the underside of the foot. The flexor hallucis longus originates from the lower two-thirds of the posterior surface of the fibula, and the flexor hallucis brevis originates from the cuboid bone and the adjacent third metatarsal bone.

Function

The hallucis muscle is responsible for flexing the big toe. This action is crucial for maintaining balance while walking and running.

Clinical significance

Damage or strain to the hallucis muscle can result in hallux limitus or hallux rigidus, conditions characterized by stiffness or limited movement of the big toe. Treatment may involve physical therapy, medication, or in severe cases, surgery.
