Nervous Tissue Review

Front

What is a glial cell?

Back

A glial cell provides protection and support to neurons.

Front

What is the function of the axon of the neuron?

Back

The axon is a long projection that conducts electrical impulses away from the cell body.

Front

What is the function of the synapse?

Back

The synapse is the space between neurons where the electrical impulse 'jumps' from one neuron to another.

Front

What part of the neuron is the soma?

Back

The soma is the cell body of the neuron, containing the nucleus.

Front

What part of the neuron is the axon?

Back

The axon is a long projection that conducts electrical impulses away from the cell body.

Front

What are dendrites?

Back

Dendrites are tree-like structures that receive messages from other neurons.

Front

What is the role of myelin sheath?

Back

The myelin sheath insulates the axon and speeds up the transmission of electrical impulses.

Front

What is the function of neurotransmitters?

Back

Neurotransmitters are chemicals that transmit signals across the synapse from one neuron to another.

Front

What is the resting potential of a neuron?

Back

Resting potential is the electrical charge difference across the neuron's membrane when it is not actively sending a signal.

Front

What is action potential?

Back

Action potential is a rapid change in the electrical charge of a neuron that occurs when it sends a signal.
