Exam 18: Nervous System Cells

What is the difference between nuclei and ganglia?

Schwann cells and oligodendrocytes share a common function, but in different parts of the nervous system.

Name and describe the three parts of the neuron.

Match each of the following cell types with its corresponding description. -Type of neuroglia that forms neurilemma

Bundles of unmyelinated fibers make up what is referred to as white matter.

The nervous system and the endocrine system share a common function of communication.

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 words nerve and neuron mean the same thing.

Most injuries to the brain and spinal cord cause permanent damage.

Cranial nerves are considered part of the CNS.

The nervous system can be divided:

What is the relationship between the afferent and efferent neurons of the reflex arc?

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

Most unipolar neurons are usually:

Gray fibers have no association with Schwann cells.

Small distinct regions of gray matter in the CNS are called:

Astrocytes attach to:

There are about 900 million glia cells in the nervous system.

The part of the nervous system that transmits impulses from the CNS to the skeletal muscle is the:

The blood-brain barrier is so effective that only water molecules are able to cross it.
