2649. FMA. 22538. Anatomical terms of muscle. [edit on Wikidata] In human anatomy, the fibularis tertius (also known as the peroneus tertius) is a muscle in the anterior compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to pull the foot upward toward the body (dorsiflexion).
The rectus femoris muscle is one of the four quadriceps muscles of the human body. The others are the vastus medialis, the vastus intermedius (deep to the rectus femoris), and the vastus lateralis. All four parts of the quadriceps muscle attach to the patella (knee cap) by the quadriceps tendon. The rectus femoris is situated in the middle of ...
The superior extensor retinaculum of the foot (transverse crural ligament) is the upper part of the extensor retinaculum of foot which extends from the ankle to the heelbone. The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on ...
The common fibular nerve (also known as the common peroneal nerve, external popliteal nerve, or lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint. It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which ...
Tarsal tunnel syndrome is the most commonly reported nerve entrapment of the ankle. It is analogous to carpal tunnel syndrome in the wrist. It is caused by compression of the tibial nerve underneath the flexor retinaculum of the foot. [ 1 ] People with tarsal tunnel syndrome have pain in the plantar aspect of the foot mostly at night.
Structure. The flexor retinaculum of the foot extends from the medial malleolus above, to the calcaneus below. [1] This converts a series of bony grooves into canals for the passage of the tendons of the flexor muscles and the posterior tibial vessels and tibial nerve into the sole of the foot, known as the tarsal tunnel.
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 posterior, medially.
The femoral artery. (Canal not labeled, but region visible at center right.) The adductor canal (also known as the subsartorial canal or Hunter's canal) is an aponeurotic tunnel in the middle third of the thigh giving passage to parts of the femoral artery, vein, and nerve. It extends from the apex of the femoral triangle to the adductor hiatus.
