| pharyngeal branch of vagus nerve | <anatomy, nerve> Conveys motor fibres from the cranial root of the accessory nerve to the pharyngeal constrictor muscles, the intrinsic muscles of the soft palate and the levator palati muscle; may also bring some general sensory fibres to the pharyngeal plexus. Synonym: rami pharyngei nervi vagi. (05 Mar 2000) |

| middle cervical cardiac nerve | <anatomy, nerve> One of the cardiopulmonary splanchnic nerves conveying postsynaptic sympathetic fibres running downward, from the middle cervical ganglion along the subclavian artery (on the left) or the brachiocephalic (on the right side) to join the cardiac plexus. Synonym: nervus cardiacus cervicalis medius. (05 Mar 2000) |
| middle meningeal branch of maxillary nerve | <anatomy, nerve> Recurrent branch of maxillary nerve distributed with the anterior branch of the middle meningeal arteyr to the meninges of the anterior portion of the middle cranial fossa. Synonym: ramus meningeus medius nervi maxillaris, middle meningeal nerve. (05 Mar 2000) |
| middle meningeal nerve | <anatomy, nerve> Recurrent branch of maxillary nerve distributed with the anterior branch of the middle meningeal arteyr to the meninges of the anterior portion of the middle cranial fossa. Synonym: ramus meningeus medius nervi maxillaris, middle meningeal nerve. (05 Mar 2000) |
| circumflex nerve | <anatomy, nerve> Arises from the posterior cord of the brachial plexus in the axilla, passes laterally and posteriorly through quadrangular space with the posterior circumflex artery, winding round the surgical neck of the humerus to supply the deltoid and teres minor muscles, terminating as the superior lateral brachial cutaneous nerve. Synonym: nervus axillaris, circumflex nerve. (05 Mar 2000) |
| middle superior alveolar branch of infraorbital nerve | <anatomy, nerve> The middle superior alveolar branch, a branch of the superior alveolar nerve that contributes to the superior dental plexus. Synonym: ramus alveolaris superior medius nervi infraorbitalis. (05 Mar 2000) |
| middle supraclavicular nerve | <anatomy, nerve> One of several nerves arising from the C-3-C-4 part of the cervical plexus which run across the top of the shoulder and pass down across the clavicle to supply the skin of the top of the shoulder and in the infraclavicular region. Synonym: nervus supraclavicularis intermedius, middle supraclavicular nerve. (05 Mar 2000) |
| phrenic nerve | <anatomy, nerve> The motor nerve of the diaphragm. The phrenic nerve fibres originate in the cervical spinal column (mostly c4) and travel through the cervical plexus to the diaphragm. (12 Dec 1998) |
| phrenicoabdominal branch of phrenic nerve | <anatomy, nerve> Terminal branches of phrenic nerve providing motor innervation of diaphragm and sensory innervation to the diaphragm and the diaphragmatic pleura and peritoneum. Synonym: rami phrenicoabdominales nervi phrenici. (05 Mar 2000) |
| mixed nerve | <anatomy, nerve> A nerve containing both afferent and efferent fibres. (05 Mar 2000) |
| coccygeal nerve | <anatomy, nerve> A small nerve, the lowest of the spinal nerves, entering into the formation of the coccygeal plexus. Synonym: nervus coccygeus. (05 Mar 2000) |
| cochlear nerve | <anatomy, nerve> The cochlear part of the acoustic (8th cranial) nerve. The cochlear nerve fibres originate from neurons of the spiral ganglion and project peripherally to cochlear hair cells and centrally to the cochlear nuclei of the brainstem. They mediate the sense of hearing. (12 Dec 1998) |
| cochlear part of vestibulocochlear nerve | <anatomy, nerve> The cochlear part of the acoustic (8th cranial) nerve. The cochlear nerve fibres originate from neurons of the spiral ganglion and project peripherally to cochlear hair cells and centrally to the cochlear nuclei of the brainstem. They mediate the sense of hearing. (12 Dec 1998) |
| cochlear root of vestibulocochlear nerve | <anatomy, nerve> One of the components of the vestibulocochlear nerve; it is made up of the central processes of the bipolar neurons which compose the spiral (cochlear) ganglion in the spiral canal of the modiolus of the bony cochlea; the cochlear root enters the cranial cavity by passing in fascicles through the spiral foraminous tract at the bottom of the internal auditory meatus; it enters the brainstem through the pontomedullary groove, closely adhering to the caudoventral aspect of the vestibular root, and distributes its fibres to the ventral and dorsal cochlear nuclei in the floor of the lateral recess of the fourth ventricle. Synonym: radix cochlearis, cochlear root of vestibulocochlear nerve, inferior root of vestibulocochlear nerve, radix inferior nervi vestibulocochlearis. (05 Mar 2000) |
| cochlear root of VIII nerve | <anatomy, nerve> One of the components of the vestibulocochlear nerve; it is made up of the central processes of the bipolar neurons which compose the spiral (cochlear) ganglion in the spiral canal of the modiolus of the bony cochlea; the cochlear root enters the cranial cavity by passing in fascicles through the spiral foraminous tract at the bottom of the internal auditory meatus; it enters the brainstem through the pontomedullary groove, closely adhering to the caudoventral aspect of the vestibular root, and distributes its fibres to the ventral and dorsal cochlear nuclei in the floor of the lateral recess of the fourth ventricle. Synonym: radix cochlearis, cochlear root of vestibulocochlear nerve, inferior root of vestibulocochlear nerve, radix inferior nervi vestibulocochlearis. (05 Mar 2000) |
