• To store energy

What are the main components of the Central Nervous System (CNS)?

• Brain and spinal cord

• Heart and lungs

• Stomach and intestines

• Breathing

• Digesting food

Reflex actions are important because they:

• Require conscious thought

• Are slow and deliberate

• Protect the body from harm

• Involve complex decision-making

Which analogy is used to describe the function of the Peripheral Nervous System?

• Like a computer processor

• Like highways and backroads

• Like a power grid

• Like a communication satellite

Which system is responsible for involuntary functions?

• Somatic Nervous System

• Autonomic Nervous System

• Central Nervous System

• Peripheral Nervous System

What is the primary function of the somatic nervous system?

• Controls involuntary movements

• Controls voluntary movements of skeletal muscles

• Regulates heart rate

• Manages digestion

When is the somatic nervous system at work?

• When you are sleeping

• When you decide to move

• When you are digesting food

• When your heart beats

What does the parasympathetic nervous system help conserve?

• Energy

• Water

• Oxygen

• Glucose

Which part of the nervous system is responsible for walking and talking?

• Autonomic Nervous System

• Central Nervous System

• Somatic Nervous System

• Peripheral Nervous System
