Nervous System

Front

What is the main function of the nervous system?

Back

The main function of the nervous system is to coordinate and control the body's responses to internal and external stimuli.

Front

What are the two main divisions of the nervous system?

Back

The two main divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).

Front

What organs make up the Central Nervous System (CNS)?

Back

The Central Nervous System (CNS) is made up of the brain and spinal cord.

Front

What is the role of the spinal cord in the nervous system?

Back

The spinal cord connects the brain to the peripheral nervous system and is responsible for transmitting signals between the brain and the rest of the body, as well as directing some reflexes.

Front

What is the function of nerves in the nervous system?

Back

Nerves are responsible for transmitting signals between different parts of the body and the central nervous system.

Front

What is the difference between voluntary and involuntary processes in the nervous system?

Back

Voluntary processes are actions that are consciously controlled by the brain, while involuntary processes occur automatically without conscious thought.

Front

What is a reflex action?

Back

A reflex action is an automatic response to a stimulus that occurs without conscious thought, often involving a direct pathway through the spinal cord.

Front

What is the role of sensory neurons in the nervous system?

Back

Sensory neurons are responsible for transmitting sensory information from the body to the central nervous system.

Front

What is the role of motor neurons in the nervous system?

Back

Motor neurons transmit signals from the central nervous system to muscles and glands, facilitating movement and responses.

Front

What is the function of the brain in the nervous system?

Back

The brain processes sensory information, coordinates responses, and is responsible for higher functions such as thinking, memory, and emotion.
