CL.5 BK.4-1-The Nervous System

What are the main components of the nervous system?

• Autonomic nervous system (ANS) and endocrine system

• Cerebral cortex and spinal cord

• Central nervous system (CNS) and peripheral nervous system (PNS)

• Somatic nervous system and immune system

What role does the brain play in the nervous system?

• The brain serves as a protective barrier for the spinal cord.

• The brain is responsible for digestion and metabolism.

• The brain acts as the control center of the nervous system, processing information and coordinating responses.

• The brain only stores memories without processing information.

How does the spinal cord function in the nervous system?

• The spinal cord functions as a communication pathway between the brain and the body, facilitating reflexes and sensory processing.

• The spinal cord is responsible for producing hormones.

• The spinal cord only controls voluntary movements.

• The spinal cord acts as a storage center for memories.

What are reflex actions?

• Reflex actions are conscious decisions made by the brain.

• Reflex actions are involuntary and automatic responses to stimuli.

• Reflex actions require a lengthy thought process before occurring.

• Reflex actions are always painful and harmful responses.

Why are reflex actions important?

• Reflex actions are only important for sports performance.

• Reflex actions are important for quick protection and survival.

• Reflex actions slow down the body's response time.

• Reflex actions are primarily for improving memory.

What should we do to protect our nervous system?

• Maintain a healthy lifestyle with a balanced diet, regular exercise, stress management, and sufficient sleep.

• Avoid all physical activity

• Sleep less to increase productivity

• Consume excessive caffeine and sugar

What systems does the nervous system control?

• Digestive system

• Muscular system, sensory system, autonomic system, endocrine system.

• Integumentary system

• Respiratory system

How do nerves transmit information in the body?

• Nerves transmit information solely through sound waves.

• Nerves transmit information through electrical signals (action potentials) and chemical signals (neurotransmitters).

• Nerves use light signals to communicate information.

• Nerves transmit information by physical movement of cells.

What activities can we perform because of the nervous system?

• Breathing and digestion

• Thinking and memory

• Hearing and vision

• We can perform activities such as movement, sensation, reflexes, and coordination.

What is the function of the circulatory system?

• To digest food and absorb nutrients.

• The function of the circulatory system is to transport blood, nutrients, gases, and waste products throughout the body.

• To regulate body temperature through sweating.

• To provide structural support to the body.
