Olfactory receptors are found in abundance in which part of the nose ?

Olfactory receptors are found in abundance in which part of the nose ? Correct Answer External surface of a nasal cavity

Concept:

  • 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 nose.
  • 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 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.
