5 Posterior clinoid process.

Comments:

The nasal turbinates (or conchae) are ledges of bone which arise from the lateral walls of the nasal cavity. The inferior meatus is the nasal passage below the inferior turbinate, the middle meatus lies between the inferior and middle turbinates, and the superior meatus lies between the superior and middle turbinates.

The hard palate is a bony structure which forms the superior border of the oral cavity and the inferior border of the nasal cavity. Posterior to this is the soft palate, a soft tissue structure containing several muscles involved in swallowing. Projecting from the posterior border of the soft palate is protuberance called the uvula.

Exam tip:

 The inferior nasal turbinate can be readily identified because it is the largest of the turbinates.
