-Cells that transfer stimuli to other cells
Resting Potential- the electrical potential of a neuron or other excitable cell relative to its surroundings when not stimulated or involved in passage of an impulse.Action Potential- the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.
Neurons
Becuase the Axon Terminals and the Dendrites cant touch, the impulse releases a chemical molecules called neurotransmitters
Motor Neurons are located in the spinal cord and synapse with muscle fibers facilitate muscle contraction with muscle spindles to modify the proprioceptive sensitivity
Sensory neurons are nerve cells that convert external stimuli from the organisms environment into internal electrical pulses
Interneurons are nerve cells whose axons and dendrites are limited to a single brain area
A synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell
Neurotransmitters are chemicals that transmit signals form a neuron to a target cell across a synapse
The sodium potassium pump is an active transport that moves sodium and potassium ions across the cell membrane
