Question

Thin plate of bone situated along the MSP at the floor of nasal cavity and forms inferior nasal septum

Answer 1

The perpendicular plate of the ethmoid bone forms the upper portion of the nasal septum within the nasal cavity. It also forms the lateral walls and extends into the nasal cavity as thin, curved projections called nasal conchae.

Step-by-step explanation:

Within the nasal cavity, the perpendicular plate of the ethmoid bone forms the upper portion of the nasal septum. The ethmoid bone also forms the lateral walls of the upper nasal cavity. Extending from each lateral wall are the superior nasal concha and middle nasal concha, which are thin, curved projections that extend into the nasal cavity.
