| neuroma, acoustic | A progressively enlarging tumour within the auditory canal arising from the eighth cranial nerve. This solitary form is usually unilateral, tends to develop later in life, and is not inherited as compared to the acoustic neuromas arising in neurofibromatosis 2. (12 Dec 1998) |
|---|---|
| neuroma, optic | A benign tumour of the optic nerve. (12 Dec 1998) |
| neuromalacia | Pathologic softening of nervous tissue. Origin: neuro-+ G. Malakia, softness (05 Mar 2000) |
| neuromast | See: lateral line sense organ. (05 Mar 2000) |
| neuromast organ | A structure in fish consisting of a long groove or canal extending along each side of the trunk and tail and branching in the head region; the groove or tube is lined with neuroepithelial cells, some of which are in groups known as neuromasts; its function appears to be the detection of vibrations of low frequency. Synonym: neuromast organ. (05 Mar 2000) |
| neuromatosis | The presence of multiple neuromas, as in neurofibromatosis. (05 Mar 2000) |
| neuromelanin | A modified form of melanin pigment normally found in certain neurons of the nervous system, especially in the substantia nigra and locus ceruleus. (05 Mar 2000) |
| neuromeningeal | Related to involvement of nervous tissue and the meninges. (05 Mar 2000) |
| neuromere | Alternate swellings and constrictions seen along the neuraxis at early stages of neural tube development, thought to be evidence of intrinsic segmentation in the CNS. Neuromeres or segments in the hindbrain region are called rhombomeres and have been shown to be lineage restriction units, each constructing a defined piece of hindbrain. (18 Nov 1997) |
| neuromimesis | An obsolete term for hysterical or neurotic simulation of disease. Origin: neuro-+ G. Mimesis, imitation (05 Mar 2000) |
| neuromimetic | Relating to the action of a drug that mimics the response of an effector organ to nerve impulses. (05 Mar 2000) |
| neuromodulation | Alteration in the effectiveness of voltage gated or ligand gated ion channels by changing the characteristics of current flow through the channels. The mechanism is thought to involve second messenger systems. (18 Nov 1997) |
| neuromodulin | <protein> Protein associated with actively growing axons, especially in the growth cone. Binds calmodulin, is phosphorylated by protein kinase C. (18 Nov 1997) |
| neuromuscular | <anatomy> Pertaining to muscles and nerves. (18 Nov 1997) |
| neuromuscular agents | Drugs used for their actions on skeletal muscle. Included are agents that act directly on skeletal muscle, those that alter neuromuscular transmission (neuromuscular blocking agents), and drugs that act centrally as skeletal muscle relaxants (muscle relaxants, central). Drugs used in the treatment of movement disorders are anti-dyskinesia agents. (12 Dec 1998) |

| neuromuscular junction |
the site of apposition of a motor end plate and the subneural cleft of the skeletal muscle fiber that it innervates. After the nerve is excited, the excitatory neurotransmitter acetylcholine is released from the axon terminal when the nerve is excited, diffuses across the synaptic cleft, and reversibly binds to receptor molecules on the muscle fiber surface, causing the initiation of an action potential that propagates along the muscle fiber and causes it to contract. Called also myoneural j.
