| communicating haematoma | 1. A cavity due to ruptured myocardial infarction that has been contained by an intact parietal pericardium and communicates with the left ventricle by a narrow neck, 2. A dilation of an artery with actual disruption of one or more layers of its walls, as at the site of puncture as a complication of precutaneous arterial catheterization, rather than with expansion of all layers of the wall. Synonym: communicating haematoma, pulsatile haematoma. (05 Mar 2000) |

| 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) |
| posterior communicating artery | <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) |
| 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) |
| ulnar communicating branch of superficial radial nerve | <anatomy, nerve> Ulnar communicating branch of superficial branch of radial nerve, joining the dorsal branch of the ulnar nerve in the hand conveying sensation from the dorsal aspect of adjacent sides of the middle and ring fingers. Synonym: ramus communicans ulnaris nervi radialis. (05 Mar 2000) |
| anastomotic veins | See: inferior anastomotic vein, superior anastomotic vein. (05 Mar 2000) |
| anonymous veins | An obsolete term for brachiocephalic veins. (05 Mar 2000) |
| anterior cardiac veins | Two or three small veins in the anterior wall of the right ventricle opening directly into the right atrium independently of the coronary sinus. Synonym: venae cordis anteriores. (05 Mar 2000) |
| anterior cardinal veins | See: cardinal veins. (05 Mar 2000) |
| anterior intercostal veins | Tributaries to the musculophrenic or internal thoracic veins from the anterior portions of intercostal spaces. Synonym: venae intercostales anteriores. (05 Mar 2000) |
