NEET PG DENTAL EXAM

Detailed explanation-1: -The vomer is one of the unpaired facial bones and forms the posteroinferior part of the bony nasal septum, lying in the midline between the two nasal cavities. It is a thin flat bone that is trapezoidal in shape with two surfaces that are obliquely grooved by the sphenopalatine (nasopalatine) vessels and nerves.

Detailed explanation-2: -The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones, and is the length of the septum. This strip of bone is called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer.

Detailed explanation-3: -The upper portion of the nasal septum is formed by the perpendicular plate of the ethmoid bone and the lower portion is the vomer bone.

Detailed explanation-4: -The nasal septum consists of bone posteriorly and cartilage anteriorly. The perpendicular plate of the ethmoid bone superiorly and the vomer inferiorly make up the bony septum. These fuse with the quadrangular cartilage, which makes up the anterior portion of the nasal septum.
