| nervus mentalis | <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) |
|---|---|
| nervus musculocutaneus | <anatomy, nerve> A major nerve of the upper extremity. The fibres of the musculocutaneous nerve originate in the lower cervical spinal cord (usually c5 to c7), travel via the lateral cord of the brachial plexus, and supply sensory and motor innervation to the upper arm, elbow, and forearm. (12 Dec 1998) |
| nervus mylohyoideus | <anatomy, nerve> A small branch of the inferior alveolar nerve given off posteriorly just before the nerve enters the mandibular foramen, distributed to the anterior belly of the digastric muscle and to the mylohyoid muscle. Synonym: nervus mylohyoideus, nerve to mylohyoid. (05 Mar 2000) |
| nervus nasociliaris | <anatomy, nerve> A branch of the ophthalmic nerve in the superior orbital fissure, passing through the orbit, giving rise to the communicating branch to the ciliary ganglion, the long ciliary nerves, the posterior and anterior ethmoidal nerves, and terminating as the infratrochlear and nasal branches, which supply the mucous membrane of the nose, the skin of the tip of the nose, and the conjunctiva. Synonym: nervus nasociliaris, nasal nerve. (05 Mar 2000) |
| nervus nasopalatinus | <anatomy, nerve> A branch from the pterygopalatine ganglion, passing through the sphenopalatine foramen, crossing to and then down the nasal septum, and through the incisive foramen to supply the mucous membrane of the hard palate. Synonym: nervus nasopalatinus. (05 Mar 2000) |
| nervus obturatorius | <anatomy, nerve> A nerve originating in the lumbar spinal cord (l2 to l4) and traveling through the lumbar plexus to the lower extremity. The obturator nerve provides motor innervation to the adductor muscles of the thigh and cutaneous sensory innervation of the inner thigh. (12 Dec 1998) |
| nervus occipitalis major | <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) |
| nervus occipitalis minor | Synonym: lesser occipital nerve. (05 Mar 2000) |
| nervus occipitalis tertius | <anatomy, nerve> Medial branch of the dorsal primary ramus of the third cervical nerve; this is usually joined with the greater occipital, but may exist as an independent nerve supplying cutaneous branches to the scalp and nucha. Synonym: nervus occipitalis tertius. (05 Mar 2000) |
| nervus octavus | <anatomy, nerve> The vestibulocochlear nerve is responsible for the sense of hearing and balance (body position sense). Lesions of the eighth nerve can result in deafness, tinnitus, dizziness, vertigo and vomiting. Synonym: cranial nerve VIII. (27 Sep 1997) |
| nervus oculomotorius | <anatomy, nerve> Responsible for motor enervation of upper eyelid muscle, extraocular muscle and pupillary muscle. Lesions of the oculomotor nerve results in ptosis (dropping eyelid), deviation of the eyeball outward, double vision and a dilated pupil. (27 Sep 1997) |
| nervus ophthalmicus | <anatomy, nerve> A sensory branch of the trigeminal (5th cranial) nerve. The ophthalmic nerve carries general afferents from the superficial division of the face including the eyeball, conjunctiva, upper eyelid, upper nose, nasal mucosa, and scalp. (12 Dec 1998) |
| nervus opticus | <anatomy, nerve> The optic nerve. The nerve carrying impulses for the sense of sight. Projection from the vertebrate retina to the midbrain. Embryologically, a CNS tract rather than a peripheral nerve. Popular experimental preparation for studies of regeneration of retino tectal projections in lower vertebrates and also for studies of glial cell lineage in CNS. Synonym: cranial nerve II. (18 Nov 1997) |
| nervus palatinus major | <anatomy, nerve> A branch of the pterygopalatine ganglion that passes downward through the greater palatine canal to supply the mucosa and glands of the hard palate, and the anterior part of the soft palate. Synonym: nervus palatinus major. (05 Mar 2000) |
| nervus pectoralis lateralis | <anatomy, nerve> A nerve that arises from the lateral cord of the brachial plexus usually passing medial to pectoralis minor to supply the sternoclavicular head of pectoralis major. Synonym: nervus pectoralis lateralis, lateral anterior thoracic nerve. (05 Mar 2000) |
