Match each part of the nervous system with its corresponding description. -PNS subdivision that transmits incoming information from the sensory organs to the CNS

Nerves that contain mostly afferent fibers are called _____ nerves.

Spinal nerves are considered part of the PNS.

Astrocytes, the star-shaped glia cells, may be able to transmit information along "astrocyte pathways."

The afferent nervous system consists of all outgoing motor pathways.

The autonomic nervous system does not stimulate:

The PNS includes both efferent and afferent nerves.

The other term for cell body is:

Cell body and perikaryon are interchangeable terms.

A neuron that has only one axon but several dendrites is classified as a _____ neuron.

What two systems perform the vital functions of communication and integration of body processes?

It is now known that fresh new neurons are often added to existing networks of neurons.

One of the components of the blood-brain barrier is:

The efferent pathways of the autonomic nervous system consist of the _____ nervous systems.

The nervous system can be divided according to structure, direction of information flow, and speed of conduction.

Name the two ways in which neurons are classified. Name and describe the types of neurons in each classification.

Dendrites conduct impulses _____ cell bodies.

After a stroke, there is usually some damage to brain tissue. What type of neuroglia would you expect to find invading the affected area?
