The sinuses connect to the nasal cavity. They are hollow cavities located within the bones surrounding the nasal cavity and are lined with a mucous membrane.
The dagger-shaped bone in the nasal cavity is called the vomer bone. It is located in the midline of the nasal cavity and helps to separate the left and right nasal passages.
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.
The nasal cavity is kept moist by the production of mucus by specialized cells called goblet cells and mucous glands. Mucus helps to trap foreign particles and pathogens, keeping the nasal cavity moist and protecting the respiratory system. Additionally, the nasal cavity has a rich blood supply that helps to maintain moisture and humidity.
Olfactory Cells
The Nose Structures.
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.
