| nervus fibularis communis | <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) |
|---|---|
| nervus fibularis profundus | <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) |
| nervus fibularis superficialis | <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) |
| nodus fibularis | A small inconstant lymph node located along the course of the peroneal vein. Synonym: nodus fibularis, fibular node, peroneal node. (05 Mar 2000) |
| sulcus tendinis musculi fibularis longi | An alternate term for groove for tendon of peroneus longus muscle. (05 Mar 2000) |
| incisura fibularis | A hollow on the lateral surface of the lower end of the tibia in which the fibula is lodged. Synonym: incisura fibularis. (05 Mar 2000) |
| trochlea fibularis calcanei | An alternate term for peroneal trochlea of calcaneus. (05 Mar 2000) |
| facies articularis fibularis tibiae | The flat circular articular facet on the inferior and lateral aspect of the lateral condyle of the tibia for articulation with the head of the fibula. Synonym: facies articularis fibularis tibiae. (05 Mar 2000) |
| fibularis | Synonym: fibular, fibular. Origin: Mod. L. (05 Mar 2000) |
| arteria communicans anterior | <anatomy, artery> A short vessel joining the two anterior cerebral arteries and completing the cerebral arterial circle (circle of Willis) anteriorly. Synonym: arteria communicans anterior. (05 Mar 2000) |
| arteria communicans posterior | <anatomy, artery> Origin, internal carotid; distribution, optic tract, crus cerebri, interpeduncular region, and hippocampal gyrus; anastomoses, with posterior cerebral to form the cerebral arterial circle (circle of Willis). Synonym: arteria communicans posterior. (05 Mar 2000) |
| macula communicans | <cell biology> A junction between two cells consisting of many pores that allow the passage of molecules up to about 900D. Each pore is formed by an hexagonal array (connexon) of six transmembrane proteins (connexins) in each plasma membrane: when mated together the pores open, allowing communication and the interchange of metabolites between cells. Electrical synapses are gap junctions and metabolic cooperation depends upon the formation of gap junctions. (18 Nov 1997) |
| communicans | Communicating; connecting or joining. Origin: L. Pres. P. Of communico, pp. -atus, to share with someone, make common (05 Mar 2000) |
| nervus communicans peroneus | 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) |
| arteriae alveolares superiores anteriores | Origin, infraorbital artery within intraorbital canal; distribution, via anterior alveolar canals to upper incisors and canine teeth, mucus membrane of maxillary sinus. Synonym: arteriae alveolares superiores anteriores, anterior superior dental arteries. (05 Mar 2000) |
