Exam 18: Nervous System Cells

Like other cells of the nervous system, glia cells have lost their capacity for cell division.

The white matter of the nervous system is made up of:

When "central" and "peripheral" are used as directional terms in the nervous system, a nerve fiber may be called peripheral if it extends from the cell body away from the CNS.

Which of the following structures is (are) not found on the axon?

The parasympathetic nervous system is part of the _____ pathway of the _____ nervous system.

The afferent pathways of the autonomic nervous system:

Astrocytes attach to:

Name and briefly describe the types of glia cells found in the nervous system.

A neuron that transmits a nerve impulse toward the central nervous system is called a(n):

Most nerves in the human nervous system are mixed.

Pathways from the autonomic nervous system that leave the CNS from the brain would be sympathetic pathways.

Fascicles are held together by a connective tissue layer called the:

Match each of the following cell types with its corresponding description. -Resembles epithelial cells and lines fluid-filled cavities in the brain and spinal cord

The myelin sheath is formed by:

In an adult, brain cells do not undergo mitosis, except to replace neurons that have been damaged or destroyed.

Which is the only glia cell that is found outside of the CNS?

Dendrites conduct impulses _____ cell bodies.

Damage to a single neuron can have a "domino" effect causing the shutdown of an entire nerve pathway.

Gray matter in the brain and spinal cord consists primarily of:

Explain how a neuron can repair itself. What increases the likelihood of repair; what decreases the likelihood of repair? If repair is not possible, what other options are possible to innervate the effector organ?
