neurons
| Question | Answer |
|---|---|
| neuroglia (glial cells) | supportive cells that provide nutrition, insulation, and help w signal transmission |
| soma (cell body) | the life support containing the nucleus and most organelles |
| dendrties | main receptors of signals, input region |
| ganglion | collection of nerve cell bodies located in the body (not the brain and spinal cord) |
| axon terminals | the end of the axon (nerve fibers) that releases neurotransmitters at a synapse when a nerve impulses is received (the security region) |
| myelin sheath | covers long axons to protect and electrically insulate them to increase speed of nerve impulse transmission |
| nodes of Ranvier | unmyelinated gaps in the myelin sheath that aid in increasing the velocity of nerve signal conduction |
