CAVUM NASALE

The nasal septum consists of:

the septal nasal cartilage anteriorly; posteriorly, mainly the vomer and the perpendicular plate of the ethmoid bone; small contributions by the nasal bones where they meet in the midline, and the nasal

spine of the frontal bone; contributions by the crests of the maxillary and palatine bones, rostrum of the sphenoid

bones, and the incisor crest of the maxilla.

Floor soft tissues of the external nose; the upper surface of the palatine process of the maxilla, and the horizontal plate of the

palatine bone, which together form the hard palate.

Roof The roof of the nasal cavity is narrow and is highest in central regions where it is formed by the cribriform plate of the ethmoid bone .

Anterior to the cribriform plate the roof slopes inferiorly to the nares and is formed by:

the nasal spine of the frontal bone and the nasal bones; the lateral processes of the septal cartilage and major alar cartilages of the external nose.

Posteriorly, the roof of each cavity slopes inferiorly to the choana and is formed by:

the anterior surface of the sphenoid bone; the ala of the vomer and adjacent sphenoidal process of the palatine bone; and the vaginal process of the medial plate of the pterygoid process.

Lateral wall The lateral wall of each nasal cavity is complex and is formed by bone, cartilage, and soft tissues. Bony support for the lateral wall is provided by:

the ethmoidal labyrinth and uncinate process; the perpendicular plate of the palatine bone; the medial plate of the pterygoid process of the sphenoid bone; the medial surfaces of the lacrimal bones and maxillae; the inferior concha.

Inervasi Cavitas Nasale

Cavitas nasale diinervasi oleh :

- Nervus Olfactory (nervus cranial I) yang berfungsi sebagai indra penciuman- Nervus Trigeminale cabang I (n. Ophtalmica) dan cabang II (n.Maxillare) sebagai sensasi umum
