| nervus interosseus posterior | <anatomy, nerve> The deep terminal branch of the radial nerve, arises in the cubital region, penetrating and supplying the supinator and continuing with the posterior interosseous artery to supply all the extensor muscles in the forearm. Synonym: nervus interosseus posterior, nervus antebrachii posterior, deep branch of the radial nerve, dorsal interosseous nerve, nervus interosseus dorsalis, posterior antebrachial nerve.

| nervus ischiadicus | <anatomy, nerve> A nerve which originates in the lumbar and sacral spinal cord (l4 to s3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the tibial nerve and the peroneal nerve. (12 Dec 1998) |
| nervus jugularis | <anatomy, nerve> A communicating branch between the superior cervical ganglion of the sympathetic nerve, the superior ganglion of the vagus nerve, and the inferior ganglion of the glossopharyngeal nerve. Synonym: nervus jugularis. (05 Mar 2000) |
| nervus lacrimalis | <anatomy, nerve> A branch of the ophthalmic nerve supplying sensory fibres to the lateral part of the upper eyelid, conjunctiva, and lacrimal gland. The secretomotor fibres of the latter were conveyed to the lacrimal nerve by the communicating branch of the zygomatic nerve (a branch of the maxillary nerve). Synonym: nervus lacrimalis. (05 Mar 2000) |
| nervus laryngeus inferior | <anatomy, nerve> The terminal branch of the recurrent laryngeal nerve; it supplies the laryngeal mucosa inferior to the vocal folds and all laryngeal muscles except the cricothyroid. Synonym: nervus laryngeus inferior. (05 Mar 2000) |
| nervus laryngeus recurrens | <anatomy, nerve> A branch of a nerve (the vagus nerve) that comes down the neck and turns back ( recurs ) to supply the larynx (the voice box ). (12 Dec 1998) |
| nervus laryngeus superior | <anatomy, nerve> A branch of the vagus nerve at the inferior ganglion; at the thyroid cartilage it divides into two branches; the internal laryngeal nerve, a sensory branch which supplies the mucous membrane of the larynx superior to the vocal folds, and the external laryngeal nerve, a motor branch which supplies the inferior pharyngeal constrictor and the cricothyroid muscle. Synonym: nervus laryngeus superior. (05 Mar 2000) |
| nervus lingualis | <anatomy, nerve> A sensory branch of the mandibular nerve, which is part of the trigeminal (5th cranial) nerve. The lingual nerve carries general afferent fibres from the anterior two-thirds of the tongue, the floor of the mouth, and the mandibular gingivae. (12 Dec 1998) |
| nervus mandibularis | <anatomy, nerve> A branch of the trigeminal (5th cranial) nerve. The mandibular nerve carries motor fibres to the muscles of mastication and sensory fibres to the teeth and gingivae, the face in the region of the mandible, and parts of the dura. (12 Dec 1998) |
| nervus massetericus | <anatomy, nerve> A muscular branch of the mandibular nerve passing through the mandibular notch to the medial surface of the masseter muscle which it supplies and the temporomandibular joint. Synonym: nervus massetericus. (05 Mar 2000) |
| nervus maxillaris | <anatomy, nerve> The intermediate sensory division of the trigeminal (5th cranial) nerve. The maxillary nerve carries general afferents from the intermediate region of the face including the lower eyelid, nose and upper lip, the maxillary teeth, and parts of the dura. (12 Dec 1998) |
| nervus meatus acustici externi | A branch of the auriculotemporal nerve supplying the lining of the external acoustic meatus. Synonym: nervus meatus acustici externi. (05 Mar 2000) |
| nervus medianus | <anatomy, nerve> A major nerve of the upper extremity. In humans, the fibres of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually c6 to t1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand. (12 Dec 1998) |
| 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.
