| efferent nerve | <anatomy, nerve> A nerve which transmits impulses from the brain and spinal cord to a muscle or organ. (27 Sep 1997) |
|---|---|
| efferent pathways | Nerve structures through which impulses are conducted from a nerve centre toward a peripheral site. (12 Dec 1998) |
| efferent vessel | A vessel carrying blood away from the heart. An artery or arteriole. (12 Dec 1998) |
| autonomic motor neuron | See: motor neuron. (05 Mar 2000) |
| bipolar neuron | A neuron that has two processes arising from opposite poles of the cell body. (05 Mar 2000) |
| magnocellular neuron | <anatomy, neurology> A neuron in the magnocellular region of the brain. Perhaps the first class of neuron from the central nervous system shown to be sensitive to nerve growth factor (that had previously been thought only to act at the periphery). (18 Nov 1997) |
| ganglionic motor neuron | See: motor neuron. (05 Mar 2000) |
| Mauthner neuron | <biology, marine biology> Large neuron in the mesencephalon of fishes and amphibians. A rare example of an individually identifiable neuron in a vertebrate nervous system. (18 Nov 1997) |
| visceral motor neuron | See: motor neuron. (05 Mar 2000) |
| cell adhesion molecules, neuron-glia | Cell adhesion molecules that mediate neuron-neuron adhesion and neuron-astrocyte adhesion. They are expressed on neurons and schwann cells, but not astrocytes and are involved in neuronal migration, neurite fasciculation, and outgrowth. Ng-cam is immunologically and structurally distinct from ncam (neural cell adhesion molecules). (12 Dec 1998) |
| Golgi type II neuron | <physiology> Nerve cells with short axons which ramify in the gray matter. (05 Mar 2000) |
| Golgi type I neuron | <physiology> Nerve cells whose long axons leave the gray matter of which they form a part. (05 Mar 2000) |
| cholinergic neuron | <physiology> Neurons in which actylcholine is the neurotransmitter. (15 Jan 1998) |
| piriform neuron layer | The layer of Purkinje cells between the molecular and granular layers of the cerebellar cortex. Synonym: stratum neuronorum piriformium, ganglionic layer of cerebellar cortex, layer of piriform neurons, Purkinje's layer, stratum gangliosum cerebelli. (05 Mar 2000) |
| motor neuron | Synonym for motoneuron. (18 Nov 1997) |
