| 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) |
| motor neuron disease | <disease> Degenerative disease of unknown cause that affects predominantly motor neurons of spinal cord, cranial nerve nuclei and motor cortex. There is speculation that deficiency in ciliary neurotrophic factor may be involved. (18 Nov 1997) |
| multipolar neuron | A neuron with several processes, usually an axon and three or more dendrites. (05 Mar 2000) |

| pseudounipolar neuron | A neuron whose cell body emits a single axonal process resulting from the fusion of two polar processes during development; at a variable distance from the cell body, the process divides into a peripheral axon branch extending outward as a peripheral afferent (sensory) nerve fibre, and a central axon branch that enters into synaptic contact with neuron's in the spinal cord or brainstem. With the single known exception of the neuron's composing the mesencephalic nucleus of the trigeminus, unipolar neuron's are the exclusive neural elements of the sensory ganglia. The lack of dendritic processes of these primary sensory neuron's is only apparent: the dendritic pole of the unipolar neuron is represented by the unmyelinated terminal ramifications of the peripheral axon branch. Synonym: pseudounipolar cell, pseudounipolar neuron, unipolar cell. (05 Mar 2000) |
| sensory neuron | 1. <anatomy> A neuron that receives input from sensory cells. 2. <physiology> Sensory cells such as cutaneous mechanoreceptors and muscle receptors. (18 Nov 1997) |
