Work Step by Step
The nasal septum is a structure that divides the nasal cavity into two halves. It is composed of several bones and cartilages, including:
1. Perpendicular plate of the ethmoid bone: This is a thin, flat bone that projects downward from the ethmoid bone and forms the upper part of the nasal septum.
2. Vomer bone: This is a thin, flat bone that forms the lower part of the nasal septum.
3. Septal cartilage: This is a flexible cartilage that forms the anterior part of the nasal septum.
Together, these structures form a solid wall that separates the left and right nasal cavities. The nasal septum provides support for the nose and helps to direct the flow of air through the nasal passages.
