| 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) |
| superior dental rami | Superior dental branches of superior dental plexus. Synonym: rami dentales superiores. (05 Mar 2000) |
| dental rami | <anatomy, dentistry> Branches to the teeth. Nomina Anatomica lists dental branches of the following: 1) anterior superior alveolar artery, rami dentales arteriarum alveolarium superiorum anteriorum; 2) inferior alveolar artery, rami dentales arteriae alveolaris inferioris; 3) inferior dental plexus, rami dentales inferiores plexus dentalis inferioris; 4) posterior superior alveolar artery, rami dentales arteriae alveolaris superioris posterioris; 5) superior dental plexus, rami dentales superiores plexus dentalis superioris. Synonym: rami dentales, dental rami. (05 Mar 2000) |
| inferior dental rami | Inferior dental branches of inferior dental plexus. Synonym: rami dentales inferiores. (05 Mar 2000) |
| interganglionic rami | The ganglionic branches, the nerve strands interconnecting the ganglia of the sympathetic trunk; they consist of pre-or postganglionic fibres passing to higher or lower levels of the trunk. Synonym: rami interganglionares. (05 Mar 2000) |
