Question

Which of the following is true of the cribriform plate?

a-It separates the nasal and cranial cavities.
b-It forms the lateral aspects of the nose.
c-It separates the internal nose from the mouth.
d-It forms a midline separation in the nasal cavity.

Answer 1

The cribriform plate is a small area with openings in the roof of the nasal cavity formed by the ethmoid bone.

Step-by-step explanation:

The cribriform plate is a small, flattened area with numerous small openings located on either side of the midline in the floor of the anterior cranial fossa.

It is formed by the ethmoid bone and is part of the roof of the nasal cavity.

Small nerve branches from the olfactory areas of the nasal cavity pass through the openings in the cribriform plate to enter the brain.
