| ventral primary rami of sacral spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum sacralium. (05 Mar 2000) |

| pars inferior rami lingularis | An alternate term for inferior part of lingular branch of left pulmonary vein. (05 Mar 2000) |
| pars infralobaris rami posterioris venae pulmonalis dextrae | <anatomy, vein> The vein draining the posterior segment of the right lung that emerges inferior to the superior lobe; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars infralobaris rami posterioris venae pulmonalis dextrae. (05 Mar 2000) |
| pars lateralis rami lobi medii venae pulmonalis dexter superior | lateral part of middle lobar branch of right superior pulmonary vein |
| pars medialis rami lobii medii venae pulmonis dextrae superioris | medial part of middle lobar branch of right superior pulmonary vein |
| pars superior rami lingularis venae pulmonis sinistri | <anatomy, vein> The vein that drains the superior lingular bronchopulmonary segment of the left lung. Synonym: pars superior rami lingularis venae pulmonis sinistri. (05 Mar 2000) |
| pars transversa rami sinistri venae portae hepatis | <anatomy, vein> The long unbranched portion of the left branch of the portal vein. Synonym: pars transversa rami sinistri venae portae hepatis. (05 Mar 2000) |
| pars umbilicalis rami sinistri venae portae hepatis | <anatomy, vein> The highly branched part of the left branch of the portal vein; the round and venous ligaments attach to this part. Synonym: pars umbilicalis rami sinistri venae portae hepatis. (05 Mar 2000) |
| cephalic arterial rami | Parietal branches of the sympathetic trunks conveying postsynaptic sympathetic fibres from the superior cervical ganglion to the carotid arteries for distribution within the head. (05 Mar 2000) |
| gray rami communicantes | 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) |
| 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) |
| white rami communicantes | 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) |
| pubic rami | See: pubes. (05 Mar 2000) |
| superior dental rami | Superior dental branches of superior dental plexus. Synonym: rami dentales superiores. (05 Mar 2000) |
