Extensor hallucis longus muscle. The mucous sheaths of the tendons around the ankle. Lateral aspect. (Ext. hall. long. labeled at upper left.) Extends (raises) the big toe and assists in dorsiflexion of the foot at the ankle. Also is a weak evertor/invertor. The extensor hallucis longus muscle is a thin skeletal muscle, situated between the ...
Extensor digitorum longus muscle. The mucous sheaths of the tendons around the ankle. Lateral aspect. (Extensor dig. longus labeled at upper right.) Animation. Details. Origin. Anterior lateral condyle of tibia, anterior shaft of fibula and superior 3⁄4 of interosseous membrane. Insertion.
A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles. The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum ...
t. e. In anatomy, extension is a movement of a joint that increases the angle between two bones or body surfaces at a joint. Extension usually results in straightening of the bones or body surfaces involved. For example, extension is produced by extending the flexed (bent) elbow. Straightening of the arm would require extension at the elbow joint.
Structure. The extensor hallucis brevis is essentially the medial part of the extensor digitorum brevis muscle. Some anatomists have debated whether these two muscles are distinct entities. The extensor hallucis brevis arises from the calcaneus and inserts on the proximal phalanx of the digit 1 (the big toe).
Craig Melvin answered a series of quetions about his TODAY co-workers on "What What Happen Live," most often naming Al Roker.
The abductor hallucis muscle is located in the medial border of the foot and contributes to form the prominence that is observed on the region. It is inserted behind on the tuberosity of the calcaneus, the flexor retinaculum, and the plantar aponeurosis. [1] Its muscle body, relatively thick behind, flattens as it goes forward.
Structure. The flexor hallucis longus is situated on the fibular side of the leg. It arises from the inferior two-thirds of the posterior surface of the body of the fibula, with the exception of 2.5 cm at its lowest part; from the lower part of the interosseous membrane; from an intermuscular septum between it and the peroneus muscles, laterally, and from the fascia covering the tibialis ...
