U4L1 Exit Ticket - Structure of a neuron

Front

What is the function of the nucleus in a neuron?

Back

The nucleus contains the cell's genetic material and controls cellular activities, including growth and metabolism.

Front

What part of the neuron receives messages from adjacent neurons?

Back

Dendrite.

Front

What is the role of the axon in a neuron?

Back

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

Front

What is myelin and its function in the nervous system?

Back

Myelin is an insulating material that surrounds axons, increasing the speed of electrical impulses.

Front

What are Schwann cells?

Back

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

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 cell body of a neuron?

Back

The cell body contains the nucleus and organelles, and is responsible for maintaining the cell's health.

Front

How do dendrites contribute to neuronal communication?

Back

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

Front

What is the significance of the myelin sheath?

Back

The myelin sheath protects axons and enhances the speed of signal transmission.

Front

What is the difference between a neuron and a glial cell?

Back

Neurons are the primary signaling cells in the nervous system, while glial cells support and protect neurons.
