• To manage only external stimuli

• To control all body processes and actions

• To regulate only voluntary actions

• To produce energy for the body

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 connects the brain and spinal cord to the rest of the body?

• Digestive system

• Autonomic nervous system

• Peripheral nervous system

• Central nervous system

Which of the following best describes the difference and primary function of sensory and motor neurons?

• Sensory neurons carry information from the central nervous system (CNS) to the muscles, while motor neurons carry information from the sense organs to the CNS.

• Sensory neurons (afferent) carry impulses from receptors toward the central nervous system, while motor neurons (efferent) carry commands from the central nervous system to effectors like muscles and glands

• Sensory neurons are responsible for voluntary movements like walking, whereas motor neurons are responsible for involuntary sensations like feeling heat or pain.

• Sensory neurons and motor neurons both carry signals away from the brain, but sensory neurons only communicate with the skin while motor neurons communicate with internal organs.

Which system controls involuntary functions like breathing and digestion?

• Autonomic system

• Somatic system

• Central nervous system

• Peripheral nervous system

What type of actions does the somatic system control?

• Involuntary actions like heartbeat

• Voluntary actions like moving your hand

• Digestive processes

• Hormonal regulation
