The olfactory mucosa is primarily composed of olfactory sensory neurons, which are responsible for detecting odors. Additionally, it contains supporting cells, which provide structural and metabolic support to the neurons, and basal cells, which are stem cells that can differentiate into new sensory neurons. Immune cells, such as macrophages and dendritic cells, are also present to help maintain mucosal health. Together, these cells play a crucial role in the functionality and maintenance of the olfactory system.
The inhibitory cells in the olfactory bulbs are called granule cells. They are involved in regulating the activity of the mitral and tufted cells, which are the principal output neurons in the olfactory bulb. Granule cells help shape and refine olfactory information processing in the brain.
chemoreceptor.
The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
Olfactory nerves, definetly. We're studying this currently in my grade.
A specialized smell receptor is situated In the roof of the nasal canal,called Olfactory mucosa. the olfactory epithelium is innervated by the olfactory(1st cranial)nerve and some branches of the 5th nerve.Olfactory epithelium contains three kinds of cells,namely olfactory receptor cells,supporting cells and basal cells.Olfactory receptor cells are sensory hair cells,sensitive to all kind of cells.Their axons terminally join the olfactory nerve. Supporting cells are mucus-secreting columnar cells. Basal cells are the stem cells from which new receptor cells are formed.Olfaction,just like taste,is a chemical sense. The molecules of the odorous substances reach the nasal canal along with the inspired air. Here, they dissolve in the mucus secretion and then attach to the receptor cells. This stimulates the receptor cells and they generate olfactory impulses. Olfactory nerves transmit these impulses to the olfactory center in the temporal lobe of the cerebrum(known as the olfactory cortex)

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 epithelium, located in the upper part of the nasal cavity, holds the olfactory receptor cells responsible for detecting smells. It contains specialized nerve cells that send signals to the brain when they detect specific odor molecules.
Enteroendocrine cells
Basal cells are stem cells in the olfactory epithelium that can regenerate olfactory sensory neurons. They differentiate into new olfactory sensory neurons to replace damaged or dying cells, helping maintain the olfactory sensory system's ability to detect and transmit odor information to the brain.
The olfactory cells are located in the olfactory epithelium, which is a specialized tissue found in the upper part of the nasal cavity. This area is covered in mucus and contains nerve endings that detect and transmit smells to the brain.
