Description
The extensor hallucis brevis muscle is a small, flat muscle located in the posterior compartment of the foot. It is situated between the two heads of the extensor hallucis longus muscle and extends from the posterior aspect of the fibula and the interosseous membrane to the extensor expansion on the dorsal aspect of the foot. This muscle is innervated by the deep fibular nerve.
The main function of the extensor hallucis brevis muscle is to extend the big toe and assist in the plantar flexion of the foot. It also helps to maintain the position of the foot in space and provides stability to the foot and ankle joint.
The extensor hallucis brevis muscle is commonly used in activities that require gripping with the big toe, such as climbing or running. It is also used in activities that require extending the big toe and plantar flexing the foot, such as standing on tiptoes or performing a calf raise.
Overall, the extensor hallucis brevis muscle plays an important role in allowing us to perform a wide range of movements with our big toe and foot.
