WebIn humans, olfaction is often considered the least acute of the senses, and a number of animals are obviously superior to humans in their olfactory abilities. This difference is probably explained by the larger number of olfactory receptor neurons (and odorant receptor molecules; see below) in the olfactory epithelium in many species and the … Web5 aug. 2024 · The olfactory system is responsible for detecting odors and converting them into signals that our brain interprets as smells. Although the sense of smell is one of the oldest senses, the ability to detect odor molecules has evolved very slowly over millions of years. The discovery of the olfactory receptors was made almost 20 years ago, in 1991. WebThey have an estimated 297 million olfactory receptors in their nasal cavity, which are responsible for detecting and interpreting different scents.

"WebCat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their heads and bodies. These senses evolved to allow cats to hunt effectively at dawn and dusk. " - How many olfactory receptors do deer have
