Nasal Cavity Anatomy RS Biology Diagrams Nose. The external nasal anatomy is quite simple. It is a pyramidal structure, with its root located superiorly and apex sitting inferiorly.The root is continuous with the anterior surface of the head and the part between the root and the apex is called the dorsum of the nose. Inferior to the apex are the two nares (), which are the openings to the nasal cavity. Nasal cavity anatomy. The term "nasal cavity" can refer to each of the two cavities of the nose, or to the two sides combined. CT scan in the coronal plane, showing the ostiomeatal complex (green area). 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 The nose is an olfactory and respiratory organ. It consists of nasal skeleton, which houses the nasal cavity. The nasal cavity has four functions: Warms and humidifies the inspired air.; Removes and traps pathogens and particulate matter from the inspired air. Responsible for sense of smell. Drains and clears the paranasal sinuses and lacrimal ducts.
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. This type of epithelial lining also secretes mucus that coats the lining and helps with the mucociliary clearance of minute aerosolized The nasal cavity consists of all the bones, tissues, blood vessels, and nerves that make up the space inside the nose. The most important functions of the nasal cavity include warming and humidifying the air as you breathe and acting as a barrier for the immune system to keep harmful microbes from entering the body. Anatomy of the Ear, Nasal Cavity, Pharynx and Larynx John Gassler PT, DPT Associate Professor of Anatomy LMU-DCOM April 5, 2019. Objectives 1. Describe the nasal cavity, its general morphology including the walls, openings, nasal septum, conchae, and meatuses. 2. Describe and identify the named portions of the pharynx, and

Structure and Anatomy Divisions. Vestibule: The area lying just posterior to the nostrils, this is the part of the nasal cavity most exposed to the threats of the environment. So, this part is lined with multiple layers of the same cells that make up our skin (stratified squamous epithelium), forming a protective barrier.
This e-Anatomy module contains 105 illustrations dedicated to the anatomy of the nose, the nasal cavity and the paranasal sinuses. These fully annotated anatomical illustrations are presented as a comprehensive atlas of the nasal cavity, specially designed for medical students, medicine residents and healthcare professionals.

Anatomy of the nasal cavity. The nasal cavity extends from the external opening, the nostrils, to the pharynx (the upper section of the throat), where it joins the remainder of the respiratory system. It is separated down the middle by the nasal septum, a piece of cartilage which shapes and separates the nostrils. Each nostril can be further
