![]() Ciliated cells Olfactory receptor cells are the cells that actually detect odors. The three types of cells in olfactory epithelium are: 1. What Are The Three Types Of Cells In Olfactory Epithelium? When the olfactory epithelium gradually loses its function or is damaged as a result of infection or aging, Bowman’s glands lose their function as well (Nakashima et al. Only olfactory neurons lack goblet cells, which are absent in the epithelium. A variety of cells, including Bowman’s gland cells (BGCs), occidental ensheathing glia (OEGs), immature olfactory sensory neurons (iOSNs), and mature olfactory sensory neurons (mOSNs), are present in this tissue. Microvillar cells (MVCs) and sustentacular cells (SUSs) act as mechanical and nutrition support for the epithelial cells. Neural pathways that process information about the environment are active. On the surface of the epithelial tissue, there are four types of cells: osteoplankocytes, osteoplankocytes, osteoplankocytes, and osteoplankocytes. ![]() Each nerve cell is replaced and regenerated twice a week, allowing it to be repaired every time it is damaged. Sensory neurons, like stem cells and progenitor cells, can be differentiated into these cells. As the odor molecule enters the nasal cavity, it is trapped by long and short microvilli that cover the apical end. The most important cell type is the olfactory sensory neuron (olfactory receptor cell). It is characterized by a disorganized cell hierarchy, as well as a diverse set of cell types. They divide to give rise to new olfactory receptor cells and support cells. Basal cells are the stem cells of the olfactory epithelium. These microvilli help to increase the surface area for the absorption of odor molecules. They are similar to sustentacular cells in that they secrete mucus, but they also have many microvilli, or small projections, on their surface. Microvillar cells are smaller than sustentacular cells and are found scattered among the olfactory receptor cells. They provide structural support to the olfactory receptor cells and also help to keep the epithelium moist by secreting mucus. They are elongated cells that span the entire length of the olfactory epithelium. Sustentacular cells are the most numerous type of support cell. There are three main types of support cells: sustentacular cells, microvillar cells, and basal cells. Support cells are non-neuronal cells that provide structural and metabolic support to the olfactory receptor cells. When an odor molecule binds to its receptor, it triggers a change in the electrical activity of the cell, which is then transmitted to the brain. These cilia are coated with olfactory receptors, which are proteins that bind to specific odor molecules. One process, the dendrite, extends into the epithelium and has numerous cilia, or hairlike extensions, on its surface. They are bipolar neurons, meaning they have a cell body with two processes extending from it. Olfactory receptor cells are the cells that actually detect odor molecules. Three main cell types make up the olfactory epithelium: olfactory receptor cells, support cells, and basal cells. The olfactory epithelium is a layer of cells that line the nasal cavity and play a role in the sense of smell.
