Document Summary

The neuron, the brain, and the nervous systems: basic structure and function. 1. connects nerve cells in the central nervous system. 1. takes some sort of physical energy from the environment and transforms it into basic information sent to the brain. 1. cause some kind of action in the body (i. e. causing muscles to relax or contract) 1. they pick up signals from other neurons. 2. transmits messages from one neuron to the next have the myelin sheath. 1. facilitates the transmition of signals to the next neuron network. 1. don"t actually touch next neuron in the network. Resting potential and action potential in a neuron. 1. change in the polarity of the neuron. 2. from a negative (-65) charge to a positive charge (+45) and then quickly back to a negative charge speed and amount fired can be affected by intensity of stimulus. When at rest, the inside is negatively charged relative to the outside positively charged particles enter.
