Olfactory Organs

Olfactory organs, also known as the sense of smell, are structures in the nose that are responsible for detecting and perceiving odors. They consist of thousands of olfactory epithelia consisting of sensory neurons that are sensitive to different concentrations of chemical substances. This allows organisms to distinguish between different odors and use them to make decisions, such as sourcing food, avoiding danger, and recognizing mates. The sense of smell is also important for social communication and the formation of memories.
