Clove is an _______ indicator.

Correct Answer Olfactory

Key PointsCONCEPT:

• Receptors are the organs or cells which respond to light, heat, or external stimulus and transmit the signal to the sensory nerve.
• The smell receptors known as chemoreceptors are present in the Olfactory Epithelium in the nose.
• Olfactory receptors are located in our noses.
• The olfactory system allows the human body to detect and process smell.
• These are also known as smell receptors and are capable of binding odor molecules.
• Most of the olfactory receptors are found on the superior or external surface of the nasal cavity.
• Olfactory receptors are present in the nose and are responsible for giving rise to the sense of smell.

EXPLANATION:

Olfactory epithelium:

• The olfactory receptors in human beings detect smell.
• Olfactory receptors are proteins that exist as clusters at the back of the nasal cavity and interact with odor molecules thus playing a role in smelling.

• The organ of smell is a yellow-tinged patch of the pseudostratified epithelium (olfactory epithelium) located on the roof of the nasal cavity.
• Air entering the nasal cavity must make a hairpin turn to stimulate olfactory receptors before entering the respiratory passageway
• This is why sniffing, which draws more air superiorly across the olfactory epithelium, intensifies the sense of smell.  
• Jacobson's Organ: The proper anatomical name for Jacobson's Organ is the Vomeronasal  Organ. The Vomeronasal Organ is a supplemental olfactory sense organ.

Cloves:

• Cloves are aromatic dried flower buds of a tree.
• Cloves are native to Indonesia and used as a spice in cuisines all over the world.
• Cloves are now harvested primarily in Indonesia, Madagascar, Zanzibar, Pakistan, and Sri Lanka.
• They are also grown in India under the name Lavang.
• The aroma and antioxidant property of Clove is due to the presence of eugenol.
