HAP 12.1: Nervous system

Front

What is the primary function of microglial cells in the nervous system?

Back

Microglial cells protect the nervous system from infection and help in the immune response.

Front

What is the role of a motor neuron?

Back

A motor neuron connects to a muscle and helps you move.

Front

What does the myelin sheath do?

Back

The myelin sheath insulates axons to increase the speed of electrical signals.

Front

What part of a neuron receives messages from other neurons?

Back

Dendrites receive messages from other neurons.

Front

What is an axon?

Back

An axon is the part of a neuron that takes information away from the cell body.

Front

What is the function of dendrites?

Back

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

Front

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

Back

The cell body contains the nucleus and organelles, and it integrates incoming signals.

Front

What are axon terminals?

Back

Axon terminals are the endpoints of an axon where neurotransmitters are released.

Front

What is the significance of the myelin sheath in neural transmission?

Back

The myelin sheath allows for faster transmission of electrical impulses along the axon.

Front

What are oligodendrocytes?

Back

Oligodendrocytes are cells that produce myelin in the central nervous system.
