Question

Which receptors are present in the tongue and nasal cavity? What are their functions?

Answer 1

Receptors

1. The specialized structures present in the cell membrane are known as receptors.
2. Receptors include sensory organs such as the eyes, ear, nose, tongue, and skin.

Receptors in tongue

Taste receptors are found on the upper surface of the tongue called taste cells.

1. The taste buds of the papillae include tongue taste receptors.
2. A taste receptor is a type of biological receptor that helps with the sense of taste.
3. Food and other chemicals interact with saliva and bind to taste receptors in the oral cavity and elsewhere as they enter the mouth.
4. Sweet, salty, sour, bitter, and umami are the five universally accepted basic tastes that stimulate and are sensed by our taste receptors.

Receptors in the nasal cavity

Olfactory receptors, or smell receptors, are found in sensory nerve cells (neurons) of nasal cavity tissues.

1. The olfactory receptor is a protein that binds scent molecules and is important in the sense of smell.
2. While chewing, specific chemicals are released, which go up to the nose and activate the olfactory receptors.
3. They collaborate with taste buds to determine the food's true flavor.
