Glossary
- Axon
- single stretch of the axon insulated by myelin and bounded by nodes of Ranvier at either end (except for the first, which is after the initial segment, and the last, which is followed by the axon terminal)
- Axon terminal with synaptic vesicles
- end of the axon, where there are usually several branches extending toward the target cell
- Dendrites
- cytoplasmic extension of the neuron receive signals and sends to the cell body
- Dorsal root ganglia
- sensory ganglion attached to the posterior nerve root of a spinal nerve
- Multipolar
- shape of a neuron that has multiple processes—the axon and two or more dendrites
- Nerves
- bundles of axons and dendrites found in the PNS throughout our body
- Synaptic end bulb
- swelling at the end of an axon where neurotransmitter molecules are released onto a target cell across a synapse
- Soma
- the cell body of the neuron
- Tracts
- bundles of axons and dendrites found in the CNS
- Unipolar
- shape of a neuron which has only one process that includes both the axon and dendrite
