Neuron Structure

Front

What are the gaps between Schwann cells that increase the speed of the transmission of the signal down the neuron called?

Back

Nodes of Ranvier.

Front

Identify the part of the neuron that contains the nucleus.

Back

Cell body.

Front

What is the long, fiber-like part of a neuron that sends information to receiving neurons?

Back

Axon.

Front

What insulating material forms a layer around the axon of a neuron and enables electrical signals to travel at higher speeds?

Back

Myelin sheath.

Front

What are the short, branched extensions of a neuron that receive signals from other neurons?

Back

Dendrites.

Front

What is the primary function of the axon in a neuron?

Back

To transmit electrical impulses away from the cell body.

Front

What is the role of the myelin sheath in neuronal function?

Back

To insulate the axon and increase the speed of signal transmission.

Front

What is the function of neurotransmitters in the nervous system?

Back

To transmit signals across the synapse from one neuron to another.

Front

What part of the neuron is responsible for processing information and integrating signals?

Back

Cell body.

Front

What is the significance of nodes of Ranvier in neuronal signaling?

Back

They allow for saltatory conduction, which speeds up the transmission of impulses.
