Front

What is the peripheral nervous system?

Back

The peripheral nervous system (PNS) is the part of the nervous system that connects the central nervous system to the limbs and organs. It includes all the nerves outside the brain and spinal cord.

Front

What is the cell body of a neuron?

Back

The cell body is the part of a neuron that contains the nucleus and organelles. It is responsible for maintaining the life of the neuron.

What protects the spinal cord?

Back

The spinal cord is protected by the vertebral column, which is made up of vertebrae.

Front

What is the role of the medulla in the brain?

Back

Front

What is the central nervous system?

Back

The central nervous system (CNS) consists of the brain and spinal cord, and it is responsible for processing information and controlling most functions of the body.

Front

What is the function of dendrites in a neuron?

Back

Dendrites are the branched extensions of a neuron that receive signals from other neurons and transmit them to the cell body.

Front

What is an axon?

Back

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

Front

What is the role of sensory neurons?

Back

Sensory neurons are responsible for carrying signals from sensory receptors (like skin, eyes, and ears) to the central nervous system.
