A nerve cell, or neuron, is a specialized cell that transmits electrical messages throughout the body.

Front

What is the main function of a nerve cell?

Back

To send electrical messages around the body.

Front

What feature of nerve cells allows them to connect with many other cells?

Back

The ends of nerve cells are branched, allowing them to connect with many other cells.

Front

How does the length of a nerve cell help in its function?

Back

The long structure of a nerve cell allows it to send messages over long distances.

Front

What is myelin?

Back

Myelin is a fatty substance that insulates nerve cells and helps messages travel faster.

Front

Why is insulation important for nerve cells?

Back

Insulation prevents the loss of electrical signals and allows messages to travel quickly.

Front

What happens when a nerve cell is damaged?

Back

When a nerve cell is damaged, it may not be able to send messages effectively, leading to loss of function.

Front

What role do dendrites play in a nerve cell?

Back

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

Front

What is the cell body of a nerve cell?

Back

The cell body contains the nucleus and is responsible for maintaining the cell's health.

Front

What is an axon?

Back

An axon is a long, thin structure that transmits electrical impulses away from the cell body.
