What does the extensor hallucis longus muscle do?
What does the extensor hallucis longus muscle do?
The extensor hallucis longus specifically extends the hallux, dorsiflexes the foot at the ankle, and inverts the foot. The extensor hallucis longus muscle is susceptible to several pathologies, including nerve injury resulting in foot drop, tendonitis, tendon rupture, and anterior compartment syndrome.
What is the action of extensor hallucis brevis?

What type of joint is the extensor hallucis longus?
The Extensor hallucis longus (EHL) is a thin muscle, situated between the Tibialis anterior and the Extensor Digitorum Longus in the anterior compartment of the lower leg. It provides the only active extension force to the interphalangeal joint and the primary active extension force to the metatarsophalangeal joint.
What does the extensor hallucis longus attach to?
The EHL originates from the anterior surface of the fibula. It is also attached to the interosseous membrane medial to the origin of the EDL. The muscular part then becomes a long tendon, which inserts on to the dorsal aspect of the distal phalanx of the hallux.
How to pronounce extensor carpi radialis brevis?
Extensor carpi radialis brevis is a fusiform muscle found in the lateral part of the posterior forearm. Together with anconeus, brachioradialis, extensor carpi radialis longus, extensor digitorum, extensor digiti minimi and extensor carpi ulnaris, it belongs to the superficial forearm extensor group. Crossing the elbow and wrist joints from their posterior aspects, these muscles produce extension at one or both of these joints.
Which muscle is an extensor?
The opposing muscle of a flexor is called the “extensor” muscle. Your triceps is an extensor. When you contract your triceps your arm straightens and the angle between the forearm and the upper arm increases. Simply so, what are the extensors?
