Neuron Structure

Front

What is the nucleus of a neuron?

Back

The nucleus is the control center of the neuron, containing the cell's genetic material and regulating its activities.

Front

What is the function of dendrites in a neuron?

Back

Dendrites are the parts of the neuron that receive messages from other neurons.

Front

What is a synapse?

Back

A synapse is the tiny gap between neurons where nerve impulses are transmitted from one neuron to another.

Front

What is a stimulus?

Back

A stimulus is a change or signal in the environment that can provoke a reaction from an organism.

Front

What role does the axon play in a neuron?

Back

The axon is the long, slender projection of a neuron that conducts electrical impulses away from the cell body.

Front

What is the myelin sheath?

Back

The myelin sheath is a fatty layer that surrounds the axon, insulating it and speeding up the transmission of nerve impulses.

Front

What is the axon terminal?

Back

The axon terminal is the endpoint of an axon where neurotransmitters are released to communicate with other neurons.

Front

What is the cell body of a neuron?

Back

The cell body contains the nucleus and organelles, and it is responsible for maintaining the life of the neuron.

Front

How do neurons communicate with each other?

Back

Neurons communicate through electrical impulses and chemical signals at the synapse.

Front

What is the difference between a stimulus and a response?

Back

A stimulus is an external change that triggers a reaction, while a response is the organism's reaction to that stimulus.
