Nervous System

The video explains the nervous system's role in processing information and controlling body functions. It is divided into the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which connects the rest of the body. The brain processes sensory information and sends signals to respond, such as moving muscles. Reflexes are quick responses to stimuli, involving the spinal cord for immediate action. Overall, the nervous system is a vital communication center for interpreting and responding to internal and external signals.

What is the role of the nervous system even during quiet moments?

• It processes information and sends nerve impulses.

• It only functions during active moments.

• It shuts down to conserve energy.

• It remains inactive.

Which part of the nervous system includes the brain and spinal cord?

• Autonomic nervous system

• Central nervous system

• Somatic nervous system

• Peripheral nervous system

What is the primary function of the peripheral nervous system?

• To interpret information

• To protect the brain

• To connect the central nervous system to the rest of the body

• To store memories

What is a reflex action?

• A slow response to stimuli

• A conscious decision

• A voluntary movement

• An automatic and quick response to stimuli

In a reflex arc, where does the signal travel first?

• To the peripheral nerves

• To the muscles

• To the spinal cord

• Directly to the brain
