| nervus cutaneus surae medialis | <anatomy, nerve> Arises from the tibial in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle. Synonym: nervus cutaneus surae medialis, medial cutaneous nerve of leg, popliteal communicating nerve, tibial communicating nerve. (05 Mar 2000) |

| nervus dorsalis clitoridis | The deep terminal branch of the pudendal, supplying especially the glans clitoridis after passing through the musculature of the urogenital diaphragm, to run along the dorsum of the clitoral shaft. Synonym: nervus dorsalis clitoridis. (05 Mar 2000) |
| nervus dorsalis penis | The deep terminal branch of the pudendal which runs through the urogenital diaphragm giving branches, then runs along the dorsum of the penis, supplying the skin of the penis, the prepuce, the corpora cavernosa, and the glans. Synonym: nervus dorsalis penis. (05 Mar 2000) |
| nervus dorsalis scapulae | <anatomy, nerve> Arises from ventral primary rami of the fifth to seventh cervical nerves and passes downward to supply the levator scapulae and the rhomboideus major and minor muscles. Synonym: nervus dorsalis scapulae, dorsal nerve of scapula, nerve to rhomboid, posterior scapular nerve. (05 Mar 2000) |
| nervus ethmoidalis anterior | <anatomy, nerve> A branch of the nasociliary nerve; passes through anterior ethmoidal foramen on superomedial wall of orbit into cranial cavity, giving rise to anterior meningeal nerves, then passes through cribriform plates into nasal cavity, supplying anterosuperior nasal mucosa. Synonym: nervus ethmoidalis anterior. (05 Mar 2000) |
| nervus ethmoidalis posterior | <anatomy, nerve> A branch of the nasociliary nerve providing sensory innervation to the sphenoidal sinus and the posterior ethmoidal air cells. Synonym: nervus ethmoidalis posterior. (05 Mar 2000) |
| nervus facialis | <anatomy, nerve> The facial nerve enervates the muscles of the face (facial expression). Lesion of the facial nerve cause a drooping to one side of the face, inability to wrinkle the forehead, inability to whistle, inability to close the eye and deviation of the mouth to the unaffected side. Synonym: cranial nerve VII. (27 Sep 1997) |
| nervus femoralis | <anatomy, nerve> A nerve originating in the lumbar spinal cord (usually l2 to l4) and traveling through the lumbar plexus to provide motor innervation to extensors of the thigh and sensory innervation to parts of the thigh, lower leg, and foot, and to the hip and knee joints. (12 Dec 1998) |
| nervus fibularis communis | <anatomy, nerve> One of the terminal divisions of the sciatic nerve, diverging from the tibial nerve at the upper end of the popliteal fossa, then coursing with the biceps tendon along the lateral portion of the popliteal space to wind around the neck of the fibula where it divides into the superficial and deep peroneal nerves. The common peroneal nerve, or its deep branch, is the most commonly injured nerve, being located in a lateral subcutaneous position at the fibular neck; a lesion causes a loss of ability to dorsiflex the foot ("foot drop"). Synonym: nervus fibularis communis, nervus peroneus communis, common fibular nerve, lateral popliteal nerve. (05 Mar 2000) |
| nervus fibularis profundus | <anatomy, nerve> One of the terminal branches of the common peroneal nerve, arising at the fibular neck and passing into the anterior compartment of the leg; it supplies the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius muscles in the leg, then crosses the ankle joint to supply the muscles on the dorsum of the foot (extensors hallucis and digitorum brevis) becoming cutaneous to innervate adjacent sides of the great and second toes. Synonym: nervus fibularis profundus, nervus peroneus profundus, anterior tibial nerve, deep fibular nerve. (05 Mar 2000) |
| nervus fibularis superficialis | <anatomy, nerve> A branch of the common peroneal nerve which passes downward in the lateral compartment of the leg to supply the peroneus longus and brevis muscles and terminate as the intermediate and medial dorsal cutaneous nerves supplying the skin of the dorsum of the foot and toes (except for adjacent sides of great and second toes). Synonym: nervus fibularis superficialis, nervus peroneus superficialis, musculocutaneous nerve of leg, superficial fibular nerve. (05 Mar 2000) |
| nervus frontalis | <anatomy, nerve> A branch of the ophthalmic nerve which divides within the orbit into the supratrochlear and the supraorbital nerves. Synonym: nervus frontalis. (05 Mar 2000) |
| nervus furcalis | <anatomy, nerve> The ventral branch of the nerve is forked to enter into the formation of both lumbar and sacral plexuses. Synonym: furcal nerve, nervus furcalis. (05 Mar 2000) |
| nervus genitofemoralis | <anatomy, nerve> Arises from the first and second lumbar nerves, passes distad along the anterior surface of psoas major muscle and divides into genital and femoral branches. Synonym: nervus genitofemoralis, genitocrural nerve. (05 Mar 2000) |
| nervus glossopharyngeus | <anatomy, nerve> The glossopharyngeal nerve enervates muscles involved in swallowing and taste. Lesions of the ninth nerve result in difficulty swallowing and disturbance of taste. Synonym: cranial nerve IX. (27 Sep 1997) |
