| sacral nerves | Five nerves issuing from the sacral foramina on either side; the ventral branches of the first three enter into the formation of the sacral plexus, and the last two into the coccygeal plexus. Synonym: nervi sacrales. (05 Mar 2000) |
|---|---|
| sacral splanchnic nerves | Branches from the sacral sympathetic trunk that pass to the inferior hypogastric plexus; part of the abdominopelvic (sympathetic) splanchnic nerves, but their specific function is unclear. They tend to be confused with the pelvic splanchnic nerves, which are much more significant structures. Synonym: nervi splanchnici sacrales. (05 Mar 2000) |
| proper palmar digital nerves | The palmar nerves of the digits of the hand derived from common palmar digital nerves; each nerve supplies a palmar quadrant of a digit and a part of the dorsal surface of the distal phalanx. Synonym: nervi digitales palmares proprii. (05 Mar 2000) |
| proper plantar digital nerves | The ten nerves derived from the common plantar digital nerves; each nerve supplies a plantar quadrant of a toe and part of the dorsal surface of the distal phalanx. Synonym: nervi digitales plantares proprii. (05 Mar 2000) |
| pterygopalatine nerves | <anatomy, nerve> The ganglionic branches, two short sensory branches of the maxillary nerve in the pterygopalatine fossa, the fibres of which pass through the pterygopalatine ganglion without synapse. Synonym: radix sensoria ganglii pterygopalatini, rami ganglionici nervi maxillaris, rami ganglionares, nervi pterygopalatini, nervi sphenopalatini, pterygopalatine nerves, sensory root of pterygopalatine ganglion. (05 Mar 2000) |
| sinuvertebral nerves | A branch from the initial (mixed) part of each spinal nerve passing in a recurrent fashion back through the intervertebral foramen to supply spinal meninges, the posterior longitudinal ligament, posterolateral periphery of the intervertebral disc, and periosteum of the vertebrae. Synonym: ramus meningeus nervorum spinalium, recurrent meningeal branch of spinal nerves, sinuvertebral nerves. (05 Mar 2000) |
| spinal nerves | The 31 paired peripheral nerves formed by the union of the dorsal and ventral spinal roots from each spinal cord segment. The spinal nerve plexuses and the spinal roots are also included. (12 Dec 1998) |
| splanchnic nerves | The major nerves supplying sympathetic innervation to the abdomen. The greater, lesser, and lowest (or smallest) splanchnic nerves are formed by preganglionic fibres from the spinal cord which pass through the paravertebral ganglia and then to the coeliac ganglia and plexuses. The lumbar splanchnic nerves carry fibres which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia. (12 Dec 1998) |
| subscapular nerves | Two branches of the posterior cord of the brachial plexus, an upper and lower, supplying the subscapularis muscle; the lower subscapular nerve also supplies the teres major muscle. Synonym: nervi subscapulares. (05 Mar 2000) |
| sudomotor nerves | Nerves containing autonomic (general visceral efferent -postganglionic) fibres that innervate sweat glands. (05 Mar 2000) |
| nuclei of cranial nerves | Groups of nerve cells associated with the cranial nerves either as motor nuclei (nuclei originis) or sensory nuclei (nuclei terminationis). Synonym: nuclei nervorum cranialium. (05 Mar 2000) |
| superior alveolar nerves | Three branches (posterior, middle, and anterior) of the maxillary nerve (or its continuation as the infraorbital nerve) that enter the maxilla to supply the mucosa of the maxillary sinus, upper teeth and gingiva. Synonym: nervi alveolares superiores, superior dental nerves. (05 Mar 2000) |
| superior cluneal nerves | Terminal branches of the dorsal primary rami of the lumbar nerves, supplying the skin of the upper half of the gluteal region. Synonym: nervi clunium superiores. (05 Mar 2000) |
| superior dental nerves | Three branches (posterior, middle, and anterior) of the maxillary nerve (or its continuation as the infraorbital nerve) that enter the maxilla to supply the mucosa of the maxillary sinus, upper teeth and gingiva. Synonym: nervi alveolares superiores, superior dental nerves. (05 Mar 2000) |
| decussation of trochlear nerves | The crossing of the two trochlear nerves at their exit through the velum medullare anterius. Synonym: decussatio nervorum trochlearium. (05 Mar 2000) |
