Back

They transmit signals between sensory neurons and motor neurons in the spinal cord.

Front

What are neuroglia?

Back

Cells that support and protect neurons in the nervous system.

Front

What is the function of sensory neurons?

Back

They carry signals from sensory receptors to the central nervous system.

Front

What is the role of motor neurons?

Back

They transmit signals from the central nervous system to muscles and glands.

Front

What are dendrites?

Back

Extensions of a neuron that receive signals from other neurons.

What is the cell body of a neuron?

Back

The part of the neuron that contains the nucleus and organelles.
