astr-,

starlike: astrocyte—star-shaped neuroglia.

ax-

axle: axon—cylindrical process that conducts impulses away from a neuron cell body.

bi-,

two: bipolar neuron—neuron with two processes extending from the cell body.

dendr-

tree: dendrite—branched process that serves as the receptor surface of a neuron.

ependym-

tunic: ependyma—neuroglia that line spaces in the brain and spinal

moving: motor neuron—neuron that stimulates a muscle to contract or a gland to release a secretion.

few: oligodendrocyte—small type of neuroglia with few cellular processes.

peri-

all around: peripheral nervous system—portion of the nervous system that consists of the nerves branching from the brain and spinal cord.

saltator-,

a dancer: saltatory conduction—impulse conduction in which the impulse seems to jump from node to node along the axon.
