Question

Sense organ in which olfactory receptors are present is:

• A. Nose
• B. Skin
• C. Tongue
• D. Inner ear

Answer 1

The Correct Option is A

Step 1: What are olfactory receptors?
Olfactory receptors are specialized nerve cells that detect smell. These receptors respond to chemical molecules in the air and send signals to the brain, helping us recognize different odours.

Step 2: Where are olfactory receptors located?
Olfactory receptors are located in the upper region of the nasal cavity, which is part of the nose. They form the main sensory system for the sense of smell.

Step 3: How do they work?
When we inhale, air carrying odour molecules enters the nose and reaches the olfactory region. The olfactory receptors detect these molecules and send electrical signals through the olfactory nerve to the brain, which processes and identifies the smell.

Step 4: Why is the nose the correct answer?
The nose is the primary sense organ for detecting smell, as it houses the olfactory receptors that are essential for the sense of smell. No other organ in the human body performs this function.

Final Answer:
Nose
