What is an interoceptor?

• A. Exteroceptor
• B. Baroreceptor
• C. Interoceptor
• D. Proprioceptor

Answer: (C)

Interoceptors are sensory receptors that monitor the body’s internal environment, detecting changes inside visceral organs and the circulatory system such as pressure, chemical composition, and distension. This internal sensing provides information for autonomic regulation and homeostasis, like how the body responds to blood pressure or gut fullness. They differ from exteroceptors, which respond to external stimuli such as touch or light, and from proprioceptors, which report on body position and movement. The term that names this class is interoceptor, and baroreceptors are an example of interoceptors because they detect blood pressure inside blood vessels.
