Neurons Structure & Function

Front

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

Back

The axon terminal is responsible for transmitting signals to other neurons by releasing neurotransmitters.

Front

What does the dendrite do in a neuron?

Back

Dendrites receive incoming signals from other neurons and transmit them to the cell body.

Front

What is the role of the cell body in a neuron?

Back

The cell body contains the nucleus and organelles, and it integrates incoming signals from the dendrites.

Front

What is the function of the axon in a neuron?

Back

The axon transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What are neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across a synapse from one neuron to another.

Front

What is the myelin sheath and its function?

Back

The myelin sheath is a fatty layer that insulates the axon, speeding up the transmission of electrical impulses.

Front

What is the synapse?

Back

The synapse is the junction between two neurons where communication occurs through neurotransmitters.

Front

What is the difference between sensory neurons and motor neurons?

Back

Sensory neurons carry signals from sensory receptors to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles.

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 transmitting 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.
