The nasal cavity is lined with a mucous membrane (a lining of tissue) that makes mucus to help keep your nose moist and prevent nose bleeds from a dry nose. There are also little hairs, called cilia, on the inside walls of the nose that filter the air you breathe in to prevent dust and dirt from getting into your lungs.

An in-depth understanding of the soft-tissue and neurovascular relationships of the maxillary sinus to the deep fascial spaces and branches of the trigeminal nerve and external carotid artery respectively is required to evaluate and report imaging involving the maxillary sinus.

The largest part of the medial wall is from the ethmoid bone. The frontal process of the lacrimal fossa and the bony nasolacrimal canal are continuous and extend into the inferior meatus of the nasal cavity. The medial wall of the ethmoid bone is actually very thin and is called the lamina papyracea.

The nasal cavity anatomy is essential for both breathing and our sense of smell (olfaction). But did you know that 80% of taste actually comes from what we smell? That is why food is almost tasteless when our nose is clogged. The nose is the most prominent part of the human face. It has internal and external parts.

The medial wall, nasal wall, or base of maxillary sinus presents, in the disarticulated bone, a large, irregular aperture, communicating with the nasal cavity. In the articulated skull this aperture is much reduced in size by the following bones: the uncinate process of the ethmoid above, the ethmoidal process of the inferior nasal concha below, the vertical part of the palatine behind, and a.
Lateral aspect of the medial wall (nasal septum) of the right nasal cavity. Nasal septum
Each is a triangular space situated anterior to the limen nasi and defined laterally by the alae nasi, medially by the membranous septum—the distal end of the cartilaginous septum—and columella nasi, and inferiorly by the adjacent floor of the nasal cavity.

The lateral wall of the nasal cavity is a region of the nasopharynx essential for humidifying and filtering the air we breathe in nasally. Here we can find a structure called agger nasi. The agger nasi is also referred to as the 'nasoturbinal concha' or 'nasal ridge.'
Nasal Cavity
The nasal cavity (Latin: cavitas nasi) is an irregular-shaped paired air-filled space located above the roof of the oral cavity. It forms the internal part of the nose. The nasal cavity is also an initial part of the respiratory system, and it lodges the olfactory receptors providing the sense of smell. Most of the nasal cavity is lined with.

Medial wall of the nasal cavity Anatomy and structure Kenhub
The medial wall of each nasal cavity, formed by the septum, is smooth and featureless, so is the floor. By contrast the lateral wall is marked by a number of features, most notably by these three delicate bony projections, the conchae, also known as the turbinate bones.
The Nasal Cavity Structure Vasculature Innervation TeachMeAnatomy
The lateral wall of each nasal cavity mainly consists of the maxilla. However, there is a deficiency that is compensated for by the perpendicular plate of the palatine bone, the medial pterygoid plate, the labyrinth of ethmoid and the inferior concha. The paranasal sinuses are connected to the nasal cavity through small orifices called ostia.

The medial wall separates the maxillary sinus from the nasal cavity, but they communicate throughout the ostium, located in the medial wall inferior or at the same level of the orbit floor. The inferior wall, known as the sinus floor, is in close relation with the posterior teeth apices, from which it is separated only by a layer of compact bone.
Nasal Cavity Anatomy
The role of the nasal cavity is to humidify and warm the inspired air. Also, as the air passes through, the nasal cavity removes minute airborne particles and other debris before the air reaches the lower airways. Columnar epithelium lines the nasal cavity.

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault ( Figure 7.3 ). The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
