• Acute pain

• Noncancer pain

• Cancer pain

• Emotional pain

What is the function of afferent pathways in the physiology of pain?

• Carry messages away from the brain via spinal cord

• Activate nociceptors

• Carry messages to the brain for interpretation

• Found in soma and viscera

Imagine Emma accidentally touches a hot stove. What role do efferent (or descending) pathways play in her experience of pain?

• Carry messages to the brain for interpretation

• Carry messages away from the brain via spinal cord

• Activate nociceptors

• Found in soma and viscera

Grace was hiking in the mountains when she accidentally brushed against a thorny bush. She felt a sharp pain immediately. Where are the nociceptors that detected this pain located in her body?

• Only in the brain

• In the spinal cord

• In soma (body tissue) and viscera (organs)

• Only in the skin

During a science experiment, Scarlett accidentally spills a chemical on her hand. She immediately feels a sharp pain. Pain receptors are sensitive to which of the following stimuli?

• Light

• Sound

• Chemical changes

• Magnetic fields

Grace accidentally touched a hot stove. What happens when her pain receptors are stimulated?

• They send impulses to the brain

• They send impulses to the spinal cord

• They stop functioning

• They adapt to the stimuli

Sophia accidentally touched a hot stove and quickly pulled her hand away. Why are pain receptors unable to adapt to repeated stimuli like this?

• They are designed to ignore stimuli

• They continue to react until stimuli are removed

• They adapt quickly to stimuli

• They are not sensitive to stimuli

What response does the Autonomic Nervous System activate?

• Rest-and-digest response

• Fight-or-flight response

• Sleep response

• Digestive response
