Interoreceptors are also known as visceral receptors.

• A. Exteroceptors
• B. Visceral receptors
• C. Proprioceptors
• D. Photoreceptors

Answer: (B)

Interoceptors monitor the body's internal environment, sensing changes inside organs and blood vessels such as stretch, chemical makeup, and temperature. Because these receptors are located in the viscera, they are also called visceral receptors. Exteroceptors detect external stimuli from the outside world (skin, senses), proprioceptors monitor body position and movement (in muscles, tendons, joints), and photoreceptors detect light in the eyes. So interoceptors and visceral receptors refer to the same set of internal-sensing receptors.
