Extensor hallucis longus muscle is a thin muscle that extends from the middle third of fibula to the distal phalanx of the big toe (hallux). The muscle belongs to the anterior compartment of the leg together with three other muscles; extensor digitorum longus, tibialis anterior and fibularis tertius muscles . The flexor hallucis longus muscle ( FHL) attaches to the plantar surface of phalanx of the great toe and is responsible for flexing that toe. The FHL is one of the three deep muscles of the posterior compartment of the leg, the others being the flexor digitorum longus and the tibialis posterior.
Extensor Hallucis Longus Muscle
Musculus flexor hallucis longus Synonyms: none Flexor hallucis longus muscle is a powerful muscle that comprises the deep layer of the posterior compartment of the leg. It belongs to a group called the deep flexors of the calf, which also include popliteus, flexor digitorum longus and tibialis posterior muscles. The extensor hallucis longus muscle is a thin skeletal muscle, situated between the tibialis anterior and the extensor digitorum longus. It extends the big toe and dorsiflects the foot. It also assists with foot eversion and inversion . Structure The muscle ends as a tendon of insertion. The extensor hallucis longus muscle is one of four muscles in the anterior compartment of the lower limb. [1] The three other muscles in the anterior compartment are the tibialis anterior, extensor digitorum longus, and fibularis tertius muscles. The Extensor hallucis longus (EHL) is a thin muscle, situated between the Tibialis anterior and the Extensor Digitorum Longus [1] 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.
flexor hallucis longus tendon pain
Flexor hallucis longus (FHL) is a powerful muscle located on the posterior aspect of the fibula below the deep fascia of the calf. In its own synovial sheath, the tendon passes downwards, deep to the flexor retinaculum, crossing the posterior ankle joint, lateral to flexor digitorum longus. The flexor hallucis longus (FHL) muscle is one of the four muscles that compose the deep posterior compartment of the lower limb. The other three deep muscles are the flexor digitorum longus (FDL), tibialis posterior, and popliteus muscles. The flexor hallucis longus originates at the posterior surface of the fibula and inserting at the plantar aspect at the base of the distal phalanx of the. The flexor hallucis longus is a muscle within the deep compartment of the posterior leg. It is located laterally within this compartment (this is slightly counter-intuitive, as it is the opposite side to the great toe). The extensor hallucis longus lies lateral to the tibialis anterior muscle and is partially covered by it. It originates from the middle third of the medial surface of the fibula and adjacent interosseous membrane. The tendon of the muscle arises within the distal portion of the leg and is oriented the same way as the body of the muscle - lateral to the tibialis anterior tendon.

The extensor hallucis longus muscle extends the foot's big toe. Also, the muscle assists in dorsiflexing, which involves moving the foot so that the toes are closer to the shins. The flexor hallucis longus ( FHL ) muscle is one of the muscles of the posterior deep compartment of the leg and along with flexor hallucis brevis muscle, is involved in flexion of the hallux (great or first toe). Its tendon passes between the medial and lateral tubercles of the talus. Its tendon sheath may communicate with the posterior ankle.
The fibers of the flexor hallucis longus muscle travel inferiorly to the foot and insert, via a long tendon, onto the plantar aspect of the base of the distal phalanx of the great toe. Key Features & Anatomical Relations The flexor hallucis longus muscle is one of the muscles of the deep part of the posterior compartment of the leg. The flexor hallucis longus muscle is one of the three major deep muscles found in the lower back region of the leg. Specifically, the muscle spans part of the calf. It is the largest and strongest.

Clinical Importance. Paralysis or weakness of the extensor hallucis longus muscle is a sign of L5 nerve root pathology, a common location for a herniated disc. This type of injury results in constant flexion of the first metatarsal secondary to an unopposed action of the flexor muscles 2. The extensor hallucis longus muscle is found in the anterior compartment of the leg. It is a long, thin, unipennate type of skeletal muscle.
