Anatomy of the nasal cavity. Nasal-associated lymphoid tissue labelled NALT. The nasal cavity is the large internal space of the nose, and is in two parts – the nasal vestibule and the nasal cavity proper. [2] The nasal vestibule is the frontmost part of the nasal cavity, enclosed by cartilages.
The nasal cavity is divided in two by the vertical nasal septum. On the side of each nasal cavity are three horizontal outgrowths called nasal conchae (singular "concha") or turbinates. These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum.
The nasalis muscle is one of the key muscles not formed or inserted correctly with cleft lip and cleft palate deformity. [5] The head of the transverse part needs to be identified during reconstructive surgery so that it can be surgically sutured (connected to) the nasal septum. [2] [5] The origin at the maxilla may also be repositioned for ...
The sphenoid sinus is a paired paranasal sinus in the body of the sphenoid bone. It is one pair of the four paired paranasal sinuses. [1] The two sphenoid sinuses are separated from each other by a septum. Each sphenoid sinus communicates with the nasal cavity via the opening of sphenoidal sinus.
In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract.The tract is divided into an upper and a lower respiratory tract.The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds.
It consists of a nasal cavity inside the head, and an external nose on the face. The external nose houses the nostrils, or nares, a pair of tubes providing airflow through the nose for respiration. Where the nostrils pass through the nasal cavity they widen, are known as nasal fossae, and contain turbinates and olfactory mucosa.
The posterior nasal spine is part of the horizontal plate of the palatine bone of the skull. It is found at the medial end of its posterior border. It is paired with the corresponding palatine bone to form a solid spine. It is the attachment of the uvula muscle.
