| vasa nervorum | Blood vessels supplying the nerves. (12 Dec 1998) |
| rami communicantes nervorum spinalium | Short nerves arising from the initial portion of the ventral primary rami of the thoracic and upper lumbar spinal nerves through which all presynaptic sympathetic nerve fibres must pass to reach the sympathetic trunks; also conveyed by the white rami communicans are visceral afferent (sensory) fibres which were conveyed to the sympathetic trunks in splanchnic nerves. Most fibres conveyed by the white rami communicantes are myelinated. Synonym: rami communicantes nervorum spinalium, communicating branches of spinal nerves. (05 Mar 2000) |

Synonym: rami cutanei anteriores pectoralis et abdominalis nervorum intercostalium, ramus cutaneus anterior (pectoralis et abdominalis) nervorum thoracicorum, anterior cutaneous nerves of abdomen, pectoral and abdominal anterior cutaneous branch of intercostal nerves.
