Exercise 15 Review

Front

What are the axons running through the central nervous system called?

Back

Tracts

Front

What does 'A' refer to in a neuron diagram?

Back

Cell body

Front

What type of neurons have many processes that issue from the cell body?

Back

Multipolar neurons

Front

Which neuroglia are found in the peripheral nervous system?

Back

Satellite cells and Schwann cells

Front

What are the branching processes of a neuron that transmit electrical signals towards the cell body called?

Back

Dendrites

Front

What is the primary function of axons in the nervous system?

Back

To transmit electrical impulses away from the cell body.

Front

What is the role of dendrites in a neuron?

Back

To receive signals from other neurons and transmit them to the cell body.

Front

What are the two main types of cells in the nervous system?

Back

Neurons and neuroglia.

Front

What is the difference between white matter and gray matter in the central nervous system?

Back

White matter contains myelinated axons (tracts), while gray matter contains neuronal cell bodies and unmyelinated axons.

Front

What is the function of Schwann cells in the peripheral nervous system?

Back

To myelinate axons, which increases the speed of electrical impulses.
