| pterygoid nerve | <anatomy, nerve> One of two motor branches, lateral and medial, of the mandibular nerve, supplying the lateral and medial pterygoid muscles with fibres of the motor root of the trigeninal nerve. Synonym: nervus pterygoideus. (05 Mar 2000) |

| secretomotor nerve | <anatomy, nerve> A nerve conveying impulses that excite functional activity in a gland. Synonym: secretomotor nerve. (05 Mar 2000) |
| secretory nerve | <anatomy, nerve> A nerve conveying impulses that excite functional activity in a gland. Synonym: secretomotor nerve. (05 Mar 2000) |
| pudendal nerve | <anatomy, nerve> Formed by fibres from the ventral primary rami of the second, third, and fourth sacral spinal nerves; it exits the pelvis via the greater sciatic foramen, passes posterior to the sacrospinous ligament, and accompanies the internal pudendal artery, into the perineum via the lesser sciatic foramen; it gives off inferior rectal nerves, then courses through the pudendal canal in the lateral wall of the ischiorectal fossa, terminating as the dorsal nerve of the penis or of the clitoris. Synonym: nervus pudendus, plexus pudendus nervosus, pudic nerve. (05 Mar 2000) |
| pudic nerve | <anatomy, nerve> Formed by fibres from the ventral primary rami of the second, third, and fourth sacral spinal nerves; it exits the pelvis via the greater sciatic foramen, passes posterior to the sacrospinous ligament, and accompanies the internal pudendal artery, into the perineum via the lesser sciatic foramen; it gives off inferior rectal nerves, then courses through the pudendal canal in the lateral wall of the ischiorectal fossa, terminating as the dorsal nerve of the penis or of the clitoris. Synonym: nervus pudendus, plexus pudendus nervosus, pudic nerve. (05 Mar 2000) |
| sensory nerve | <anatomy, nerve> An afferent nerve conveying impulses that are processed by the central nervous system so as to become part of the organism's perception of self and its environment. (05 Mar 2000) |
| sensory root of trigeminal nerve | <anatomy, nerve> The large sensory root of the trigeminal (or fifth cranial) nerve, extending from the semilunar ganglion into the pons through the middle cerebellar peduncle or brachium pontis, immediately lateral to the small motor root. Synonym: radix sensoria nervi trigemini, portio major nervi trigemini. (05 Mar 2000) |
| short ciliary nerve | <anatomy, nerve> One of a number of branches of the ciliary ganglion, supplying the ciliary muscles, iris, and tunics of the eyeball. Synonym: nervus ciliaris brevis. (05 Mar 2000) |
| short saphenous nerve | <anatomy, nerve> A branch of the tibial nerve which supplies sensory innervation to parts of the lower leg and foot. (12 Dec 1998) |
| sinus nerve of Hering | <anatomy, nerve> A branch of the glossopharyngeal nerve that innervates the baroreceptors in the wall of the carotid sinus and the chemoreceptors in the carotid body. Synonym: ramus sinus carotici, carotid sinus branch, Hering's sinus nerve, intercarotid nerve, nerve to carotid sinus, sinus nerve of Hering. (05 Mar 2000) |
| hypogastric nerve | <anatomy, nerve> One of the two nerve trunks (right and left) which lead from the superior hypogastric plexus into the pelvis to join the inferior hypogastric plexuses. Synonym: nervus hypogastricus. (05 Mar 2000) |
| hypoglossal nerve | <anatomy, nerve> The hypoglossal nerve enervates the muscles of the tongue. Lesions of the twelfth cranial nerve result in deviation of the tongue toward the paralysed side and thick speech. Synonym: cranial nerve XII. (27 Sep 1997) |
| small deep petrosal nerve | <anatomy, nerve> One of two sympathetic branches from the internal carotid plexus to the tympanic plexus. Synonym: nervus caroticotympanicus, small deep petrosal nerve. (05 Mar 2000) |
| smallest splanchnic nerve | <anatomy, nerve> One of the abdominopelvic splanchnic nerves arising in the thorax and penetrating the diaphragm to supply presynaptic sympathetic fibres for the renal plexus; often combined with the lesser splanchnic nerve, but occasionally existing as an independent nerve. Synonym: nervus splanchnicus imus, smallest splanchnic nerve. (05 Mar 2000) |
| small sciatic nerve | <anatomy, nerve> Arises from the first three sacral nerves, supplies the skin of the posterior surface of the thigh and of the popliteal region (S1 and S2 component); it gives off a perineal branch (S3 component) that passes to the lateral aspect of the scrotum or labia majora. Synonym: nervus cutaneus femoris posterior, posterior cutaneous nerve of thigh, small sciatic nerve. (05 Mar 2000) |
