Question

Which of the following receptor classifications could be considered enteroreceptors?

• A. Chemoreceptors
• B. Photoreceptors
• C. Visceroreceptors
• D. Both (a) and (c)

Answer 1

The correct option is D Both (a) and (c)

• Enteroceptor - any receptor that responds to stimuli inside the body.

• Chemoreceptors: consists of aortic and carotid bodies. Aortic body detects changes in blood oxygen and carbon dioxide, but not pH, while carotid body detects all three.
• visceroreceptors group of receptors that includes those located in visceral organs. Their stimulation gives rise to poorly localized and ill-defined sensations or to pain. In hollow visceral organs, they are stimulated principally by excessive contraction or by distention.

Since both chemoreceptors and visceroreceptors respond to stimuli inside the body, these can be categorized under enteroreceptors.

So, the correct answer is 'Both (a) and (c)'.
