the brain and spinal cord, interprets input and dictates motor responses

the spinal and cranial nerves, sensing input from the body and sending information to tissues

A subdivision of the PNS, is also known as the afferent division, via the somatic and visceral afferent nerv e fibers

A subdivision of the PNS, is also known as the efferent division, involves the organs, muscles, and glands

from the CNS to the skeletal muscles, known as the voluntary nervous system

including the smooth muscles, cardiac muscles, and glands, also known as the involuntary nervous system

excitable nerve cells

star cells, connect neurons to capillaries

small and ovoid, long "thorny" process, monitor health of neurons and assist them

ciliated, lines cavities, circulates cerebral spinal fluid around the CNS

has few processes, wrap process around thicker neuron fibers in CNS, produce myelin sheaths

surround neuron cell bodies within ganglia in PNS

Surround and form myelin sheaths around the larger nerve fibers; found in PNS

Which is not a part of a neuron?

clusters of cell bodies in the CNS

short diffusely branched input, convey electrical information toward the cell body

clusters of cell bodies in the PNS

Beginning at he axon hillock forms the nerve fiber, generates and conducts impulses on the axolemma

myelinated fibers tracts

nerve cell bodies and unmyelinated fibers

3 or more processes, 1 axon and the rest are dendrites

1 axon and 1 dendrite

1 branch that divides into two portions

impulses toward the CNS

impulses away from the CNS to effector organs

between sensory and motor, where integration occurs

measure of potential energy generated by separate charges

hindrance to the flow of electrical charges

flow of electrical charge between two points
