| centrifugal nerve | <anatomy, nerve> A nerve which transmits impulses from the brain and spinal cord to a muscle or organ. (27 Sep 1997) |
| centripetal nerve | <anatomy, physiology> A nerve which transmits impulses from the tissues to the brain and spinal cord (for example sensory nerve). (27 Sep 1997) |
| cervical branch of facial nerve | <anatomy, nerve> The most inferior branch of the parotid plexus of the facial nerve, it descends to innervate the platysma muscle. Synonym: ramus colli nervi facialis, ramus cervicalis nervi facialis. (05 Mar 2000) |
| meningeal branch of mandibular nerve | <anatomy, nerve> A recurrent branch of the mandibular nerve that passes superiorly through foramen spinosum to be distributed with the posterior division of the middle meningeal artery to the meninges of the posterior portion of the middle cranial fossa. Synonym: ramus meningeus nervi mandibularis, nervus spinosus. (05 Mar 2000) |
| meningeal branch of ophthalmic nerve | <anatomy, nerve> See: tentorial nerve. (05 Mar 2000) |
| meningeal branch of vagus nerve | <anatomy, nerve> A branch of the superior ganglion of the vagus supplying the meninges of the posterior cranial fossa. Synonym: ramus meningeus nervi vagi. (05 Mar 2000) |
| mental branches of mental nerve | <anatomy, nerve> Branches of the mental nerve providing general sensory innervation to the skin of the chin. Synonym: rami mentales nervi mentalis. (05 Mar 2000) |
| mental nerve | <anatomy, nerve> A branch of the inferior alveolar nerve, arising in the mandibular canal and passing through the mental foramen to the chin and lower lip. Synonym: nervus mentalis. (05 Mar 2000) |
| pericardial branch of phrenic nerve | <anatomy, nerve> One of the branches of phrenic nerve distributed to the pericardium and adjacent mediastial parietal pleura. Synonym: ramus pericardiacus nervi phrenici. (05 Mar 2000) |
| perineal branches of posterior femoral cutaneous nerve | <anatomy, nerve> Branches of posterior femoral cutaneous nerve which convey sensory fibres to the skin of the lateral-most perineum and adjacent portions of the upper medial thigh. Synonym: rami perineales nervi cutanei femoris posterioris. (05 Mar 2000) |
| mesencephalic nucleus of trigeminal nerve | <anatomy, nerve> A long, narrow plate of unipolar neurons extending throughout the length of the midbrain, in and along the lateral angle of the central gray substance. The nucleus is the single known instance of primary sensory neurons enclosed in the central nervous system instead of in a peripheral sensory ganglion. Its peripheral axonal processes pass with the trigeminal nerve, give collaterals to the trigeminal motor nucleus, and terminate in the muscles of mastication. Synonym: nucleus tractus mesencephali nervi trigemini. (05 Mar 2000) |
| mesencephalic tract of trigeminal nerve | <anatomy, nerve> Located alongside the central substance of the midbrain and composed of primary sensory fibres, the cells of origin of which compose the mesencephalic nucleus of the trigeminus. Synonym: tractus mesencephalicus nervi trigemini. (05 Mar 2000) |
| great auricular nerve | <anatomy, nerve> Arises from the ventral primary rami of the second and third cervical, spinal nerves, supplies the skin of part of the auricle, adjacent portion of the scalp, and that overlying the angle of the jaw; it also innervates the parotid sheath, conveying from it the pain fibres stimulated by stretching of the sheath during parotitis (mumps). Synonym: nervus auricularis magnus. (05 Mar 2000) |
| greater occipital nerve | <anatomy, nerve> Medial branch of the dorsal primary ramus of the second cervical nerve; sends branches to the semispinalis capitis and multifidus cervicis, but is mainly cutaneous, supplying the back part of the scalp. Synonym: nervus occipitalis major. (05 Mar 2000) |
