Exam 14: Touch and Pain

When a person's head moves in any particular direction, the endolymph sloshes from one direction to another.If a person moves the head left, the endolymph piles up along that side, triggering a neural response.This allows the vestibulatory receptors to ______.

A-delta fibers are myelinated nociceptors that conduct signals rapidly and respond to both heat and pressure.

The three tubes located in the inner ear responsible for the signaling of head rotation are known as ______.

The pathway for the nociceptors (pain) and thermoreceptors (temperature) that travels up the contralateral side of spinal column is known as the ______.

When the dorsal horn receives feedback from the cerebral cortex, it can ______.

How is the sensation of itch similar to the sensation of pain?

The sensory system responsible for the perception of balance and acceleration, housed in the semicircular canals and otolith organs, both located adjacent to the inner ear, is known as the ______.

Which of the following is a distinction among the three neuroanatomical regions of the primary somatosensory cortex?

When Klatzky gave participants 100 common objects to touch and identify, she found that ______.

The dorsal column-medial lemniscal pathway is a pathway for the nociceptors (pain) and thermoreceptors (temperature) that travels up the contralateral side of spinal column and does not synapse in the brain until the ventral posterior nucleus of the thalamus.

Dirk is in the woods on a dark night without a flashlight.He needs to use a specific tool mixed in with a dozen other items in his backpack.Explain how haptic perception can apply to Dirk's situation.

Pacinian corpuscles are ______.

Nonmyelinated nociceptors that are slower and that respond to pressure, extreme degrees of either heat or cold, and toxic chemicals are known as ______.

Pruriceptors are receptors in our skin that respond to mild irritants by producing itch sensations.

The somatosensory cortex is an area in the parietal lobe of the cerebral cortex that ______.

Larry steps on a hornet and is stung in the foot.He is in a great deal of pain, so he begins crying and becomes very upset.Larry's unpleasant emotional experience due to pain is associated with a portion of the prefrontal lobe of the brain known as the ______.

The continued but illusory sensory reception in a missing appendage is known as ______.

Sensory receptors in the skin that, when activated, cause us to feel pain, found in both the epidermis and dermis, are known as ______.

Chemicals produced by the body that reduce pain throughout the body are known as ______.
