Question

Osphradium of Pila can be categorized into which of the following types of receptors?
(a)Chemoreceptor
(b)Photoreceptor
(c)Tangoreceptor
(d)Phonoreceptor

Answer 1

Hint: A receptor is a protein molecule generally found embedded within the plasma membrane that receives signals from outside the cell. When such signals bind with a receptor they make some kind of cellular or tissue response.

Complete answer:
Osphradium of Pila can be categorized into a chemoreceptor. Chemoreceptors detect the chemical changes or presence of chemicals in the surrounding.
Osphradium is an olfactory organ that is connected with the respiratory organs. The main function of osphradium is to test the incoming water for silt and also check for the possible food particles. This organ is found in all the members of the genus Conus, the cone snails, these belong to the predatory sea snails. Receptors are of many kinds according to their functions. Such as chemoreceptors, thermoreceptors, photoreceptors, Tangoreceptor, phonoreceptors, etc.

Additional Information:
 -Photoreceptors detect visible electromagnetic radiation. They convert light or these radiations into signals that can stimulate biological processes. e.g retina of the eye
-Tangoreceptors detect the sense of touch here the whole body surface serves as tangoreceptor, except for parts covered with thick, rigid shells (as in mollusks).
-Phonoreceptors detect the sound or similar vibrations in the surrounding.
-Thermoreceptors detect the changing temperature of the surroundings.
-Similarly, mechanical forces have been detected by mechanoreceptors.
So, the correct answer is,’chemoreceptor’

Note:
-The chemoreceptors also help to maintain the appropriate oxygen, carbon dioxide, and pH in the body with the help of a variety of cardiovascular and respiratory reflexes.
-Taste buds are the direct example of a chemoreceptor; they are highly sensitive to chemicals in the mouth.
-The carotid bodies and aortic bodies are clusters of cells located on the carotid artery, so peripheral chemoreceptors detect the changes that occur in the pH value inside the body.
