Understanding Neurons and Their Functions

What is the primary function of a neuron?

• To provide nutrients to other cells

• To transmit electrical signals

• To produce hormones

• To store genetic information

Answer explanation

The primary function of a neuron is to transmit electrical signals, allowing communication between different parts of the body. This is essential for processing information and coordinating responses.

Which of the following is NOT a main part of a neuron?

• Cell body

• Dendrites

• Axon

• Myelin sheath

Answer explanation

The myelin sheath is not a main part of a neuron; it is a protective covering that insulates the axon. The main parts of a neuron are the cell body, dendrites, and axon.

What larger system are neurons a foundational component of?

• Digestive system

• Respiratory system

• Nervous system

• Circulatory system

Answer explanation

Neurons are specialized cells that transmit information throughout the body, making them a foundational component of the nervous system, which controls and coordinates all bodily functions.

Which part of the neuron is responsible for receiving signals from other neurons?

• Axon

• Cell body

• Dendrites

• Nucleus

Answer explanation

Dendrites are the parts of the neuron that receive signals from other neurons. They act as the input channels, allowing communication between neurons, while the axon transmits signals away from the cell body.

What is the role of other cells that support neurons?

• To transmit electrical signals

• To provide nutrients and necessary materials

• To produce electrical signals

• To store information

Answer explanation

Other cells, known as glial cells, support neurons by providing nutrients and necessary materials for their function and maintenance, ensuring the overall health of the nervous system.
