| neuromuscular relaxant | An agent, e.g., curare or succinylcholine, that produces relaxation of striated muscle by interruption of transmission of nervous impulses at the myoneural junction. (05 Mar 2000) |

| neuromuscular spindle | A fusiform end organ in skeletal muscle in which afferent and a few efferent nerve fibres terminate; it contains from 3 to 10 striated muscle fibres (intrafusal fibres) that are much smaller than the ordinary muscle fibres, are separated from them by a capsule that encloses the organ, and are innervated by the thin axon of a gamma motoneuron (gamma motor fibre); the sensory endings that occur on the intrafusal fibres are either annulospiral or flower spray endings; this sensory end organ is particularly sensitive to passive stretch of the muscle in which it is enclosed. Synonym: Kuhne's spindle, muscle spindle. (05 Mar 2000) |
| neuromuscular system | The muscles of the body collectively and the nerves supplying them. (05 Mar 2000) |
| nondepolarising neuromuscular blocking agent | A compound that paralyzes skeletal muscle primarily by inhibiting transmission of nerve impulses at the neuromuscular junction rather than by affecting the membrane potention of motor endplate or muscle fibres. (05 Mar 2000) |
