Question

A feeling of pain in one’s stomach would be due to
A. Exteroceptors
B. Telereceptors
C. Proprioceptors
D. Interoceptors

Answer 1

Receptors are a group of proteins that binds ligands or other protein molecules to stimulate a response against certain stimuli. There are two types of receptors; cell surface receptors that are present on the surface of the cells and internal receptors that are present inside the cell.

Step by step answer: Pain from inside or the outer muscle wall of the abdomen is characterized as stomach pain. The sensory receptor picks up the signal of pain and transmits it to the brain to detect the cause of stimulus and return back to homeostasis. These sensory receptors are classified into three types on the basis of the location of the stimulus-
Exteroceptors- these receptors are present on the skin cells, the hair cells of the inner ear, and retinal photoreceptors. These receptors bring information from the external world into the body.
Proprioceptors- these receptors bring information from the muscles, tendons, joint capsules, and ligaments to the brain. They signal the pain and performance of movements of muscles.
Teloreceptors- these are a type of sensory receptors such as the visual or auditory receptor that are stimulated by distant objects. They mediate the far sense.
Interoceptors- these sensory receptors are a very large group of sensory nerve endings including the receptors distributed through various tissues and internal organs such as the heart, lungs, stomach, etc. these are sensitive to chemical stimuli that sense the changes in metabolism, temperature, pain, etc.
Hence, the correct option is D. Interoceptors

Note: The interoceptors are further classified into mechanoreceptors that respond to changes in tissues, chemoreceptors that respond to changes in chemical stimuli and thermoreceptors that respond to changes in temperature.
