| nerve growth factors | Factors which enhance the growth potentialities of sensory and sympathetic nerve cells. (12 Dec 1998) |
|---|---|
| nerve implantation | Planting one nerve into the sheath of another nerve. (05 Mar 2000) |
| nerve impulse | An action potential. (18 Nov 1997) |
| nerve net | A meshlike structure composed of interconnecting nerve cells that are separated at the synaptic junction or joined to one another by cytoplasmic processes. In invertebrates, for example, the nerve net allows nerve impulses to spread over a wide area of the net because synapses can pass information in any direction. (12 Dec 1998) |
| nerve of external acoustic meatus | A branch of the auriculotemporal nerve supplying the lining of the external acoustic meatus. Synonym: nervus meatus acustici externi. (05 Mar 2000) |
| nerve of pterygoid canal | The nerve constituting the parasympathetic and sympathetic root of the pterygopalatine ganglion; it is formed in the region of the foramen lacerum by the union of the greater superficial petrosal and the deep petrosal nerves, and runs through the pterygoid canal to the pterygopalatine fossa. Synonym: nervus canalis pterygoidei, radix facialis, facial root, vidian nerve. (05 Mar 2000) |
| nerve of smell | Collective term denoting the numerous olfactory filaments: slender fascicles each composed of the thin, unmyelinated axons of 8 to 12 of the bipolar olfactory receptor cells in the olfactory portion of the nasal mucosa; the olfactory filaments pass through the cribriform plate of the ethmoid bone and enter the olfactory bulb, where they terminate in synaptic contact with mitral cells, tufted cells, and granule cells. See: olfactory tract. Synonym: nervi olfactorii, fila olfactoria, first cranial nerve, nerve of smell, olfactory fila. (05 Mar 2000) |
| nerve of tensor tympani muscle | <anatomy> A branch of the mandibular nerve conveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor tympani muscle. Synonym: nervus tensoris tympani. (05 Mar 2000) |
| nerve of tensor veli palatini muscle | <anatomy> A branch of the mandibular nerveconveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor veli palatini muscle. Synonym: nervus tensoris veli palatini. (05 Mar 2000) |
| nerve of tympanic membrane | Sensory branch of the auriculotemporal nerve supplying the external surface of the tympanic membrane. Synonym: ramus membranae tympani nervi auriculotemporalis, nerve of tympanic membrane. (05 Mar 2000) |
| nerve pain | An obsolete term for neuralgia. (05 Mar 2000) |
| nerve plexus | A plexus formed by the interlacing of nerves by means of numerous communicating branches. Synonym: plexus nervosus. (05 Mar 2000) |
| nerve regeneration | Renewal or physiological repair of damaged nerve tissue. (12 Dec 1998) |
| nerve root | One of the two bundles of nerve fibres (dorsal and ventral roots) emerging from the spinal cord that join to form a single segmental (mixed) spinal nerve; some of the cranial nerves are similarly formed by the union of two roots, in particular the fifth or trigeminal nerve; in the case of the eighth cranial (vestibulocochlear) nerve, each of its two components (vestibular root and cochlear root) is referred to as a root even though they do not join each other and their central connections are distinctive, conjoined nerve root, two adjacent nerve root's with the same common origin from the dura mater. (05 Mar 2000) |
| nerve root sleeve | In myelography, the funnel-shaped extension of the opacified subarachnoid space that surrounds each nerve root as it enters its neural foramen. (05 Mar 2000) |
