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 a stimulus?

Back

A stimulus is a change or signal in the environment that can make an organism react.

Front

What part of the neuron receives messages from adjacent neurons?

Back

The dendrite is the part of the neuron that receives messages from adjacent neurons.

Front

What are axon terminals?

Back

Axon terminals are the endpoints of an axon where neurotransmitters are released to communicate with other neurons.

Front

What is the function of dendrites?

Back

Dendrites are branched extensions of a neuron that receive signals from other neurons.

Front

What is the role of the axon in a neuron?

Back

The axon is a long, thin structure that transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What is the myelin sheath?

Back

The myelin sheath is a fatty layer that insulates the axon and speeds up the transmission of electrical signals.

Front

What are Schwann cells?

Back

Schwann cells are a type of glial cell that produce the myelin sheath around axons in the peripheral nervous system.

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

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.
