👉 Noseolus is a term used in anatomy that describes the structure of the nasal cavity, specifically referring to the opening at the back of the nose, which is called the "nose olfactory epithelium." This epithelium is responsible for producing and secreting olfaction, the ability to detect and discriminate odors. It plays a crucial role in the sense-making process and can be found on both left and right sides of the nasal cavity.
