| communicating hydrocele | Associated with patent processus vaginalis. (05 Mar 2000) |
|---|---|
| communicating hydrocephalus | Type of hydrocephalus in which there is an abnormality in cerebrospinal fluid absorption; there is no obstruction to cerebrospinal fluid flow in the ventricular system or where the cerebrospinal fluid passes into the spinal canal. (05 Mar 2000) |
| communicating junction | <cell biology> Another name for a gap junction. (05 Jan 1998) |
| communicating rami of spinal nerves | The communicating branches of spinal nerves, small bundles of nerve fibres connecting spinal nerves with sympathetic ganglia; the fibres passing from the ganglion to the spinal nerve are nonmyelinated and are called gray rami communicantes, those passing in the reverse direction are myelinated and are called white rami communicantes. (05 Mar 2000) |
| communicating rami of sympathetic trunk | Short nerves arising from the lateral aspect of the sympathetic trunk conducting nonmyelinated postsynaptic sympathetic nerve fibres from the sympathetic trunk to the initial portions of all 31 pairs of ventral primary rami of spinal nerves for distribution by all parts (including the dorsal primary ramus) of the spinal nerve. The gray rami are the parietal branches of the sympathetic trunks since all postsynaptic fibres to be distributed to the body wall (including limbs) must pass through them. Synonym: communicating branches of sympathetic trunk, communicating rami of sympathetic trunk. (05 Mar 2000) |
| popliteal communicating nerve | <anatomy, nerve> Arises from the tibial in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle. Synonym: nervus cutaneus surae medialis, medial cutaneous nerve of leg, popliteal communicating nerve, tibial communicating nerve. (05 Mar 2000) |
| tibial communicating nerve | <anatomy, nerve> Arises from the tibial in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle. Synonym: nervus cutaneus surae medialis, medial cutaneous nerve of leg, popliteal communicating nerve, tibial communicating nerve. (05 Mar 2000) |
| acetabular branch | An arterial branch that supplies the acetabulum; two arteries, the obturator and the medial femoral circumflex, have such branches. Synonym: ramus acetabularis, acetabular artery, arteria acetabuli. (05 Mar 2000) |
| anastomotic branch | The anastomotic branch, a blood vessel that interconnects two neighboring vessels. It should not be used for the nervous system, because there is no analogy between a vascular anastomosing branch and a connection between nerves or their subdivisions. Synonym: ramus anastomoticus. (05 Mar 2000) |
| anterior basal branch | Anterior basal branch of basal parts of the inferior lobar branches of the right and left pulmonary arteries, and superior basal branches of the right and left inferior pulmonary veins. Synonym: ramus basalis anterior. (05 Mar 2000) |
| anterior branch | The anterior branch of the following: great auricular nerve lateral cerebral sulcus left and right superior pulmonary veins medial cutaneous nerve of the forearm obturator artery obturator nerve renal artery right branch of portal vein right hepatic duct superior thyroid artery ulnar recurrent artery. Synonym: ramus anterior. (05 May 2002) |
| anterior cutaneous branch of iliohypogastric nerve | <anatomy, nerve> Distribution, skin on pubis. Synonym: ramus cutaneus anterior nervi iliohypogastrici, genital branch of iliohypogastric nerve. (05 Mar 2000) |
| apical branch | The apical branch of the following: 1) superior lobar branches of left and right pulmonary arteries; 2) left superior pulmonary vein. Synonym: ramus superior. Synonym: ramus apicalis. (05 Mar 2000) |
| apicoposterior branch of left superior pulmonary vein | <anatomy, vein> Drains apicoposterior bronchopulmonary segment of superior lobe of left lung. Synonym: ramus apicoposterior venae pulmonalis sinistrae superioris. (05 Mar 2000) |
| ascending anterior branch | The ascending anterior branch of the superior lobar branches of the left and right pulmonary arteries. Synonym: ramus anterior ascendens. (05 Mar 2000) |
