What is not true about the Long Buccal Nerve?

The statement regarding the Long Buccal Nerve supplying the buccinator muscle is not true. The Long Buccal Nerve is primarily responsible for providing sensory innervation to the buccal mucosa and skin over the buccinator area. While it does interact with the buccinator by providing sensation, it does not supply motor innervation to the muscle itself, as the buccinator is innervated by the facial nerve.

In contrast, the other statements accurately describe the Long Buccal Nerve's functions. It does indeed pass through the heads of the pterygoid muscles, which is a relevant anatomical feature. Additionally, it supplies sensory innervation to the mucosa over the lower molars, which is important for sensory feedback in the oral cavity, and it also provides sensory information to the skin covering the buccinator muscle. Understanding these distinctions is crucial for recognizing the specific functions of the Long Buccal Nerve in dental practice.
