nervous

What is the primary function of the nervous system?

• To process visual information

• To coordinate all activities of the body

• To regulate heart and blood vessel function

• To control muscle movements

What is the largest section of the brain?

• The midbrain

• The medulla oblongata

• The cerebellum

• The cerebrum

How many main sections does the brain have?

• Four

• Six

• Five

• Three

What is the function of the cerebellum?

• Directing sensory impulses

• Regulating heart function

• Muscle coordination and balance

• Processing auditory information

What role does the hypothalamus play?

• It regulates autonomic nervous system functions

• It connects the brain and the spinal cord

• It processes visual information

• It is responsible for muscle coordination

What does the spinal cord connect?

• The brain and the heart

• The brain and the peripheral nerves

• The cerebrum and the cerebellum

• The thalamus and the hypothalamus

What is the function of afferent neurons?

• Regulating heart and blood vessel function

• Carrying information from the brain to the body

• Processing sensory information

• Carrying information from the body to the brain

What are the two subdivisions of the peripheral nervous system?

• The central and the external nervous systems

• The afferent and the efferent nervous systems

• The somatic and the autonomic nervous systems

• The sympathetic and the parasympathetic nervous systems

What triggers the sympathetic nervous system?

• The need for sleep

• Imminent danger

• Hunger and thirst

• Muscle coordination

What does the parasympathetic nervous system do?

• It processes auditory information

• It brings the body back to normal after a threat

• It slows down the heart rate

• It prepares the body for action
