| Name: | CaP motoneuron |
|---|---|
| Synonyms: | CAP motoneurons, caudal primary motoneuron |
| Definition: | A primary motor neuron part of the spinal cord. The CaP motoneuron is found within 1 soma diameter of the ventral root. The axon of the CaP motoneuron extends ventrally from the ventral root, within the space between the notochord and the medial surface of the axial muscles. Below the notochord, the axon extends within the ventral median septum to the ventral edge of the axial muscles, where it turns dorsally and laterally to project over the lateral surface of the axial muscles. |

| Name: | microtubule |
|---|---|
| Synonyms: | microtubuli, microtubulus, neurotubule |
| Definition: | Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle. |
