EXPRESSION ANATOMY:
| 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: | synapse |
|---|---|
| Synonyms: | electrotonic synapse, mixed synapse, synaptic junction |
| Definition: | The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
