Where are the olfactory receptors located?
O Tongue
Inner ear
Nasal cavity
Eye

Olfactory receptors are primarily located in the nasal cavity, specifically in a small region called the olfactory epithelium. This specialized tissue contains millions of receptor cells that can detect a wide array of odors, sending signals to the brain to help us recognize and differentiate between various scents.

Curiously, humans have about 5 million olfactory receptors, which may sound like a lot, but dogs have around 300 million! This incredible olfactory capability is why dogs are often used in search and rescue missions, detecting drugs, or even identifying certain medical conditions based solely on scent. Isn’t that pawsitively mind-blowing?
