Question 8

A patient comes to the emergency department complaining of a dull, aching pain in his lower abdomen. He is experiencing pain carried on

Accepted Answer

Dull, aching pain is carried on slow pain fibers, which provide a longer-lasting, persistent sensation of pain. Fast pain fibers carry sharp, immediate pain sensations. Nociceptors are specialized nerve endings that respond to painful stimuli, and the spinoreticular tract is involved in pain modulation and descending pain inhibition.

a.sclera
f.ciliary body
b.cornea
g.lens
c.retina
h.anterior cavity
d.iris

Accepted Answer

The answer of Match each eye structure to its location...

Question 10

A patient comes to the hospital with a severe crush injury of the leg. He is complaining of severe pain. He also says he is feeling very nauseous and, after a few minutes, vomits. What is the best explanation for the nausea and vomiting?

Accepted Answer

Pain signals traveling along the spinoreticular tract carried signals to the hypothalamus and limbic system, triggering nausea as a response to pain.

Question 11

Match the name of each sensory receptor to the type of sensation detected by each.
a.chemoreceptor
d.nociceptor
b.mechanoreceptor
e.photoreceptor
c.thermoreceptor

Question 14

Match the name of each sensory receptor to the type of sensation detected by each.
a.chemoreceptor
d.nociceptor
b.mechanoreceptor
e.photoreceptor
c.thermoreceptor
f.proprioceptor
-Respond to tissue damage; also known as pain receptors

Accepted Answer

The answer of Match the name of each sensory receptor...

Question 15

Which statement about sensory receptors is true?

Accepted Answer

The intensity of pain does depend on the number of fibers stimulated. When more fibers are stimulated, the brain perceives the stimulus as more intense. This is why a paper cut or a small burn may be painful but not unbearable, while a large wound or burn can be excruciating.

Question 16

Identify the proper path of the main pain pathway, beginning with the site of injury and ending at the point where the person becomes aware of pain.

Accepted Answer

The proper path of the main pain pathway begins with injured tissues stimulating nociceptors, with the pain signal traveling to the dorsal horn of the spinal cord, and then the spinothalamic tract relays the pain signal to the thalamus. The thalamus relays the pain signal to the postcentral gyrus, where the person becomes aware of pain. This is the correct and most commonly accepted path of the main pain pathway. Choices B, C, and D are not correct because they include incorrect steps or pathways.
