Neurotransmitter

Front

What is the function of dendrites in a neuron?

Back

Dendrites receive signals from other neurons.

Front

What is the role of the myelin sheath?

Back

The myelin sheath insulates axons and speeds up nerve impulse transmission.

Front

What are glial cells?

Back

Glial cells support and protect neurons in the nervous system.

Front

What is an action potential?

Back

An action potential is a rapid change in electrical charge that travels along the axon.

Front

What is the difference between sensory neurons and motor neurons?

Back

Sensory neurons carry signals to the CNS, while motor neurons carry signals away from the CNS to muscles.
