| peroneal artery | <anatomy, artery> Origin, posterior tibial; distribution, soleus, tibialis posterior, flexor longus hallucis, peroneal muscles, inferior tibiofibular articulation, and ankle joint; anastomoses, anterior lateral malleolar, lateral tarsal, lateral plantar, dorsalis pedis. Synonym: arteria peronea, arteria fibularis, fibular artery. (05 Mar 2000) |

| peroneal bone | A long bone in the lower leg that is adjacent to the tibia. The fibula supports approximately 1/6th of the body weight and produces the lateral (outer) prominence of the ankle. (27 Sep 1997) |
| peroneal communicating branch | The peroneal (fibular) communicating branch of the common peroneal (fibular) nerve; it arises from the common peroneal nerve in the popliteal space and passes over the lateral head of the gastrocnemius to the middle third of the leg, where it unites with the medial sural cutaneous nerve to form the sural nerve. Synonym: ramus communicans fibularis nervi fibularis communis, ramus communicans peroneus nervi peronei communis, nervus communicans fibularis, nervus communicans peroneus, peroneal anastomotic ramus, peroneal communicating nerve.

| peroneal communicating nerve | The peroneal (fibular) communicating branch of the common peroneal (fibular) nerve; it arises from the common peroneal nerve in the popliteal space and passes over the lateral head of the gastrocnemius to the middle third of the leg, where it unites with the medial sural cutaneous nerve to form the sural nerve. Synonym: ramus communicans fibularis nervi fibularis communis, ramus communicans peroneus nervi peronei communis, nervus communicans fibularis, nervus communicans peroneus, peroneal anastomotic ramus, peroneal communicating nerve. (05 Mar 2000) |
| peroneal muscular atrophy | A group of three familial peripheral neuromuscular disorders, sharing the common feature of marked wasting of the more distal extremities, particularly the peroneal muscle groups, resulting in "stork legs." Two of the three subtypes are hereditary sensorimotor polyneuropathies, one demyelinating in type and the other axon loss in type, while the third subgroup is an anterior horn cell disorder. It usually involves the legs before the arms; pes cavus is often the first sign; autosomal dominant, autosomal recessive, and X-linked recessive types, with severity related to genetic type. Synonym: Charcot-Marie-Tooth disease. (05 Mar 2000) |
| peroneal nerve | <anatomy, nerve> The lateral of the two terminal branches of the sciatic nerve. The peroneal (or fibular) nerve provides motor and sensory innervation to parts of the leg and foot. (12 Dec 1998) |
| peroneal node | A small inconstant lymph node located along the course of the peroneal vein. Synonym: nodus fibularis, fibular node, peroneal node. (05 Mar 2000) |
| peroneal phenomenon | Tapping the peroneal nerve below the head of the fibula causes dorsiflexion and abduction of the foot. (05 Mar 2000) |
| peroneal pulley | A projection from the lateral side of the calcaneus between the tendons of the peroneus longus and brevis. Synonym: trochlea peronealis, trochlea fibularis calcanei, peroneal pulley, processus trochlearis, spina peronealis, trochlear process. (05 Mar 2000) |
| peroneal retinaculum | Superior and inferior fibrous bands retaining the tendons of the peroneus longus and brevis in position as they cross the lateral side of the ankle. Synonym: retinacula musculorum peroneorum, retinacula musculorum fibularium, retinacula of peroneal muscles. (05 Mar 2000) |
| peroneal trochlea of calcaneus | A projection from the lateral side of the calcaneus between the tendons of the peroneus longus and brevis. Synonym: trochlea peronealis, trochlea fibularis calcanei, peroneal pulley, processus trochlearis, spina peronealis, trochlear process. (05 Mar 2000) |
| peroneal veins | Venae comsitantes of the peroneal artery; they join the posterior tibial veins to enter the popliteal vein. Synonym: venae peroneae, venae fibulares, fibular veins. (05 Mar 2000) |
| common peroneal nerve | <anatomy, nerve> One of the terminal divisions of the sciatic nerve, diverging from the tibial nerve at the upper end of the popliteal fossa, then coursing with the biceps tendon along the lateral portion of the popliteal space to wind around the neck of the fibula where it divides into the superficial and deep peroneal nerves. The common peroneal nerve, or its deep branch, is the most commonly injured nerve, being located in a lateral subcutaneous position at the fibular neck; a lesion causes a loss of ability to dorsiflex the foot ("foot drop"). Synonym: nervus fibularis communis, nervus peroneus communis, common fibular nerve, lateral popliteal nerve. (05 Mar 2000) |
| common peroneal tendon sheath | The sheath that surrounds the tendons of the peroneus longus and brevis muscles in their passage across the ankle. Synonym: vagina tendinum musculorum peroneorum communis, vagina tendinum musculorum fibularium communis. (05 Mar 2000) |
| communicating branch of peroneal artery | <anatomy, artery> The communicating branch of the peroneal (fibular) artery. Synonym: ramus communicans arteriae fibularis, ramus communicans arteriae peroneae. (05 Mar 2000) |
