Exploring the Human Nervous System

Which of the following structures is part of the peripheral nervous system (PNS)?

• Brain

• Spinal cord

• Cranial nerves

• Brainstem

What are the two main divisions of the human nervous system?

• Central nervous system and peripheral nervous system

• Autonomic nervous system and somatic nervous system

• Sympathetic nervous system and parasympathetic nervous system

• Sensory nervous system and motor nervous system

What are the four main functions of the human nervous system?

• Detects stimuli, sends information, interprets impulses, produces appropriate responses

• Controls muscles, regulates temperature, sends signals, and processes emotions

• Manages body temperature, detects light, interprets sound, and produces movement

• Coordinates bodily functions, analyzes data, sends impulses, and regulates hormones

In the context of daily activities, what is the role of the nervous system in responding to stimuli?

• It only detects stimuli without generating any response

• It sends information to the brain and produces appropriate responses to stimuli

• It only interprets impulses without affecting body movements

• It coordinates digestive processes without involvement in sensory detection

What are voluntary actions characterized by?

• They are unconscious actions and occur without will.

• They are automatic responses controlled by the spinal cord

• They are conscious actions conducted under one's will and controlled by the brain

• They are reflex actions that do not involve the brain

Which of the following is an example of a voluntary action?

• Breathing

• Touching a hot surface

• Reading a book

• Heartbeat regulation

In the example provided, what is the stimulus when the phone rings?

• Touching the screen

• The phone ringing

• The nerve impulse

• The action of answering the call

In a voluntary action, which structure is responsible for sending the nerve impulse from the receptor to the effector?

• The muscle

• The gland

• The brain

• The affector
