The nasopalatine nerve traverses the nasal septum from posterior to anterior in a. The oral cavity and its bony components (maxilla and mandible), along with the nose and its related sinuses, constitute most of the face.

The Caucasian Nose Occupies The Middle Third Of The Face Vertically And The Middle Fifth Horizontally.

The nasal septum divides the cavity into two cavities, also known as fossae. The nostrils or external nares. The upper third is bony and formed by the nasal bones (nb) and the frontal process of the maxilla.

Air Enters The Nasal Cavity From The Outside Through Two Openings:

Openings into the nasal cavity. The external nose can also be described in thirds. Air flows superiorly into the nares, determined by its position and the anterior nasal valve.

The Maxillary Branches Of The Trigeminal Nerve That Innervate The Nose And Nasal Cavity Branch In Or Near The Pterygopalatine Fossa Then Enter The Nasal Cavity.

The airstream then turns posteriorly approximately 90° and flows into the nasopharynx. Each nasal cavity is divided by three turbinates. Their locations and structures are best viewed when the head is shown in sagittal section.

The Nose And Nasal Cavity Constitute The Main External Opening Of The Respiratory System.

Because of their proximity, disease in one may affect the other, whereas trauma of the midface will involve bones common to the oral cavity, nose, and paranasal sinuses. The nose is made out of bone, muscle, cartilage and skin, while the nasal cavity is, more or less, hollow space.
