# Pterygomandibular raphe is a tendon between which of the following muscles?
A. Masseter and medial pterygoid
B. Anterior belly of the digastric and Buccinator
C. Buccinator and Superior constrictor
D. Buccinator and Masseter


The correct answer is C. Buccinator and Superior constrictor.

Pterygomandibular raphe acts as a tendon between the buccinator and superior Constrictor muscle. It is a landmark used often for the identification of the pterygomandibular space for the administration of an inferior alveolar nerve block.

The injecting needle pierces the buccinator muscle to inject the local anesthetic solution in the pterygomandibular space.
