 # Which radiographic landmark extends inferiorly from the medial pterygoid plate?

A. Nasolabial fold

B. Hamular process

C. Zygomatic process

D. Maxillary tuberosity

The correct answer is B. Hamular process.

The radiographic landmark that extends inferiorly from the medial pterygoid plate is the hamulus (or hamular process) of the sphenoid bone.

The hamular process is a small, hook-like projection that extends downward from the medial pterygoid plate. It is visible on certain radiographic views, such as panoramic or lateral cephalometric radiographs, and serves as an attachment point for structures like the pterygomandibular raphe and the tensor veli palatini muscle.
