olfactory |älˈfakt(ə)rē; ōl-|adjectiveof or relating to the sense of smell : the olfactory organs.It is an adjective so it is used to describe anything that has to do with the sense of smell.ex. Reptiles have two distinct olfactory systems - the main olfactory system, and the accessory olfactory system.orAs of now, there is no theory that explains olfactory perception completely.
Proprioceptors are specialized sensory receptors that provide information about body position and movement, typically found in muscles, tendons, and joints. The olfactory epithelium, responsible for the sense of smell, primarily contains olfactory receptors that detect odor molecules. It does not contain proprioceptors, as its function is to transduce chemical signals rather than provide feedback on body position. Therefore, proprioceptors are not present in the olfactory epithelium.
Yes, olfactory receptors synapse with mitral cells in the olfactory bulb. When odor molecules bind to olfactory receptors in the nasal epithelium, they activate sensory neurons that send signals to the olfactory bulb. In the olfactory bulb, these sensory neurons synapse with mitral cells, which then relay the olfactory information to higher brain regions for processing. This synaptic connection is crucial for the perception of smell.
The olfactory receptor neurons in the nose are the only neurons in the body that routinely undergo mitosis to replace damaged or aging cells. Other neurons in the central nervous system typically do not undergo mitosis and have limited capacity for regeneration.
You can find chemoreceptors in your tongue (taste buds) and in your olfactory system (your nose).
Nose
The olfactory nerve is responsible for the sense of smell in the human body. It transmits signals from the nose to the brain, allowing us to detect and identify different odors.

The receptors of smell, known as olfactory receptors, are located in the upper part of the nasal passages. They are found in the olfactory epithelium, a specialized tissue located in the roof of the nasal cavity.
in the olfactory bulb
Bipolar neurons are found in the retina and olfactory nerve in the nose.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Axons from the olfactory nerve project to the olfactory bulb in the brain. The olfactory bulb processes and relays information about smells to other areas of the brain, such as the olfactory cortex, where scent perception occurs.
Olfactory nerve to the brain's olfactory bulb, where they are processed and interpreted as specific smells. The olfactory nerve is responsible for carrying information about odors from the nose to the brain.
