| hereditary peroneal nerve dysfunction | <neurology> A slowly progressive genetic disorder characterised by muscle atrophy in the feet and the legs, progressing to the hands and arms, due to a disorder involving the destruction of nerves (degeneration of the myelin sheath). Other features include foot drop and a slapping gait. There is no specific treatment for this disorder. (27 Sep 1997) |
| short peroneal muscle | <anatomy, muscle> Origin, lower two-thirds of lateral surface of fibula; insertion, base of fifth metatarsal bone; action, everts foot; nerve supply, superficial peroneal. Synonym: musculus fibularis brevis, musculus peroneus brevis, short fibular muscle, short peroneal muscle. (05 Mar 2000) |
| superficial peroneal nerve | <anatomy, nerve> A branch of the common peroneal nerve which passes downward in the lateral compartment of the leg to supply the peroneus longus and brevis muscles and terminate as the intermediate and medial dorsal cutaneous nerves supplying the skin of the dorsum of the foot and toes (except for adjacent sides of great and second toes). Synonym: nervus fibularis superficialis, nervus peroneus superficialis, musculocutaneous nerve of leg, superficial fibular nerve. (05 Mar 2000) |
| deep peroneal nerve | <anatomy, nerve> One of the terminal branches of the common peroneal nerve, arising at the fibular neck and passing into the anterior compartment of the leg; it supplies the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius muscles in the leg, then crosses the ankle joint to supply the muscles on the dorsum of the foot (extensors hallucis and digitorum brevis) becoming cutaneous to innervate adjacent sides of the great and second toes. Synonym: nervus fibularis profundus, nervus peroneus profundus, anterior tibial nerve, deep fibular nerve. (05 Mar 2000) |
| third peroneal muscle | <anatomy, muscle> Origin, in common with musculus extensor digitorum longus; insertion, dorsum of base of fifth metatarsal bone; nerve supply, deep branch of peroneal; action, assists in dorsiflexion and eversion of foot. Synonym: musculus fibularis tertius, musculus peroneus tertius, third peroneal muscle. (05 Mar 2000) |
| long peroneal muscle | <anatomy, muscle> Origin, upper two-thirds of outer surface of fibula and lateral condyle of tibia; insertion, by tendon passing behind lateral malleolus and across sole of foot to medial cuneiform and base of first metatarsal; action, plantar flexes and everts foot; nerve supply, superficial peroneal. Synonym: musculus fibularis longus, musculus peroneus longus, long fibular muscle, long peroneal muscle. (05 Mar 2000) |
| carotid artery, common | The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (carotid artery, external) and internal (carotid artery, internal) carotid arteries.
