These cells reside in the CNS and provide the myelination for axons.

These cells are found between nerves and blood vessels. They regulate concentrations of ions and nutrients.

These cells reside in the PNS and provide myelination for axons.

Also called nerve cells. They transmit signals to one another and effectors by action potentials.

These cells cover brain parts, form inner linings within the brain and the spinal cord

These cells reside in the CNS, look spider-like, and dispose of debris, dead brain cells, and bacteria.

a nerve cell with two processes

a nerve cell with one process that splits once it leaves the cell body

a nerve cell with many processes

nerve cells that carry information from body parts to the CNS

nerve cells that are entirely in the brain or spinal cord

nerve cells that carry information from the CNS to effectors

bipolar

interneurons

motor

unipolar

the junction between two communicating neurons

the path that nerve impulses travel on from neuron to neuron

the neuron that is sending a message from its cell body through its axon

the neuron that is receiving the message in its dendrites

these increase the ability for a nerve to send an impulse/trigger impulses

these decrease the chance that the nerve will send an impulse
