Exercise 15 Review

Front

What does CNS stand for in the context of the nervous system?

Back

CNS stands for Central Nervous System, which includes the brain and spinal cord.

Front

What is the function of the cell body in a neuron?

Back

The cell body contains the nucleus and organelles, and it is responsible for maintaining the cell's health and processing information.

Front

What is the endoneurium?

Back

The endoneurium is a delicate connective tissue that surrounds each individual axon within a nerve.

Front

What are the two types of neuroglia found in the peripheral nervous system?

Back

Satellite cells and Schwann cells.

Front

What are dendrites and what is their role in a neuron?

Back

Dendrites are branching processes of a neuron that receive signals and transmit electrical impulses towards the cell body.

Front

What is the primary role of the central nervous system?

Back

The primary role of the CNS is to process and integrate information from the body and coordinate responses.

Front

How do Schwann cells contribute to nerve function?

Back

Schwann cells form the myelin sheath around axons in the peripheral nervous system, which helps increase the speed of electrical impulses.

Front

What is the difference between the central nervous system and the peripheral nervous system?

Back

The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes all the nerves outside the CNS.

Front

What is the significance of myelin in the nervous system?

Back

Myelin is a fatty substance that insulates axons, allowing for faster transmission of electrical signals.

Front

What are the main components of a neuron?

Back

The main components of a neuron are the cell body, dendrites, and axon.
