The medial wall of the nasal cavity comprises the nasal septum, the septal cartilage and various bones of the skull. This article covers each structure and concludes with a summary of the the most important facts. Contents Nasal skeleton Ethmoid bone Maxillary bone Vomer Palatine bone Nasal cartilage and associated structures 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 of the nasal cavity is formed by the nasal septum. Anteriorly, it is continuous with the septal cartilage of the external nose. Posteriorly, it Is formed by the bony perpendicular plate of ethmoid (superiorly) and the vomer (inferiorly).

These pathways are called meatuses: Inferior meatus - between the inferior concha and floor of the nasal cavity. Middle meatus - between the inferior and middle concha. Superior meatus - between the middle and superior concha. Spheno-ethmoidal recess - superiorly and posteriorly to the superior concha. 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.

Bones, cartilages and mucosa of the medial wall of the nasal cavity. Nasal septum Septum nasi 1/12 Synonyms: none The nasal septum is the midline vertical partition which separates the nasal cavity into left and right halves, forming the medial wall of each half. It is comprised of bony and cartilaginous parts. 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. 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 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.

1.2 Medial Wall of Nasal Cavity: Nasal Septum The nasal septum is constituted by the septal cartilage and four bones: the perpendicular plate of the ethmoid, the vomer, septal crests of the palatine, and maxillary bones. 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.
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. 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, also known as the nasal fossa, forms part of the upper respiratory tract. Terminology Somewhat confusingly, the nasal cavity may refer to either the space either side of the nasal septum or the two spaces combined. 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.'
