| intercalary | 1. Inserted or introduced among others in the calendar; as, an intercalary month, day, etc.; now applied particularly to the odd day (Feb. 29) inserted in the calendar of leap year. See Bissextile. 2. Introduced or inserted among others; additional; supernumerary. "Intercalary spines." "This intercalary line . . . Is made the last of a triplet. <medicine>" (Beattie) Intercalary day, one on which no paroxysm of an intermittent disease occurs. Origin: L. Intercalaris, intercalarius: cf. F. Intercalaire. See Intercalate. Source: Websters Dictionary (01 Mar 1998) |

| 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) |

| 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) |

| 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) |
