The plasma membrane of cells in the axon

Wandering, mobile, phagocytes that are looking for pathogenic material to destroy

Occur when a neuron is stimulated by chemicals, light, heat, or mechanical disturbances

The important characteristic of action potentials that states once an action potential is generated it can not be stopped until it arrives at its destination

This period functions to prevent action potentials from going backwards

Other names for this structure on the axon are perikaryon and soma

They surround the axonal fiber like a bubble and myelinate fibers of the PNS

Cl- in extracellular fluid and PO4^(2-) in intracellular fluid are known as

These channels slowly open to counteract depolarization

The integration of multiple different presynaptic neurons each producing a few action potentials

Extensions of the cell body that are in charge of afferent information

These cells contributes to the blood-brain barrier and looks like a star

These require no ATP and allow ions to go through simple diffusion through them based on the ions concentration gradients

This ion is used to reverse local potentials

Many of these are added together to make the membrane more and more polarized and eventually culminating in the reaching of the threshold, staring an action potential T

This specific neuron is seen in sensory impulses and has one connection into the soma that splits off into a dendrite and an axon

These cells are epithelial cells that line the cavities and produce CSF

The characteristic of local potential signals to get weaker as they get farther from their origin

The property of living cells that tells us that one side of the membrane will be positively charged and the other side of the membrane will be negatively charged

Where one neuron is submitting a high frequency of action potentials arriving at a postsynaptic neuron creating a whole host of localized events

The critical place where all information going into the soma is integrated before it is established if an impulse will travel down the axon

This cell has the same job as schwann cells do in the PNS but are in the CNS and help to prevent the jumbling of information and increase the velocity of nerve impulses

This action decreases the potential across the cell membrane due to the opening of gated Na+ channels

The area of axon between schwann cells, where we have no myelination

Potassium voltage-gated channels stay open longer than sodium channels do, producing this negative overshoot
