Bones. Bones of the nose and septal cartilage. Roof of the mouth showing position of palatine bones making up the floor of the nose, and forming the posterior nasal spine for the attachment of the musculus uvulae. The bony structure of the nose is provided by the maxilla, frontal bone, and a number of smaller bones.
The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose. Each has two surfaces and four borders.
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.
The nasal septum contains bone and hyaline cartilage. It is normally about 2 mm thick. The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone; Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone
Cat anatomy comprises the anatomical studies of the visible parts of the body of a domestic cat, which are similar to those of other members of the genus Felis. Mouth [ edit ] Sharp spines or papillae found in a cat's tongue. 5 types of papillae can be found in the dorsal aspect of the tongue: filiform, fungiform, foliate, vallate, and conical.

Nasal bridge is the bony part of the nose, overlying the nasal bones, above the part in blue labeled "Cartilage of Septum". The bridge is between the eyes, and just below them. The lower half of the nose is below the bridge.
The nasalis muscle is a sphincter-like muscle of the nose. It has a transverse part and an alar part. It compresses the nasal cartilages, and can "flare" the nostrils. It can be used to test the facial nerve (VII), which supplies it.
