Describe the pathway that pain signals take from the site of injury to the brain.

• Pain signals travel directly to the brain without any intermediate stops.

• Pain signals travel from the site of injury to the spinal cord and then to the brain.

• Pain signals are processed in the muscles before reaching the brain.

• Pain signals bypass the spinal cord and go directly to the brain.

• The perception of sound

• The feeling of pain

How does the gate control theory explain the modulation of pain?

• Pain is only perceived when the gate is closed.

• Pain signals are blocked by a "gate" in the spinal cord.

• Pain is amplified by opening the gate in the brain.

• Pain is unaffected by the gate mechanism.

Explain how context can influence the perception of a visual illusion.

• Context has no effect on visual perception.

• Context can alter the perceived size or shape of objects in an illusion.

• Context only affects auditory illusions.

• Context enhances the accuracy of visual perception.

Which receptor is primarily responsible for detecting temperature changes?

• Meissner's corpuscles

• Thermoreceptors

• Nociceptors

• Photoreceptors

What is the primary difference between sensation and perception?

• Sensation involves interpretation, while perception involves detection.

• Sensation is the detection of stimuli, while perception is the interpretation of those stimuli.

• Sensation occurs in the brain, while perception occurs in the spinal cord.

• Sensation is voluntary, while perception is involuntary.
