The '''buccal nerve''' is a [[nerve]] in the face. It is a branch of the [[mandibular nerve]] (which is itself a branch of the [[trigeminal nerve]]) and transmits sensory information from [[skin]] over the [[buccal membrane]] (in general, the [[cheek]]) and from the second and third [[Molar (tooth)|molar]] [[teeth]].
==Course==
It courses between the two heads of the [[lateral pterygoid muscle]], underneath the [[tendon]] of the [[temporalis muscle]], and then under the [[masseter muscle]] to connect with the [[buccal branch of the facial nerve|buccal branches of the facial nerve]] on the surface of the [[buccinator muscle]].
===Target===
Small branches of the buccal nerve innervate the [[lateral pterygoid muscle]]. It also gives sensory branches to the [[cheek]].
==Related nerves==
The [[facial nerve]] (CN VII) also has [[buccal branches]], which carry motor innervation to the buccinator muscle, a muscle of facial expression. This should not be confused with the buccal branch of the trigeminal nerve, which supplies motor innervation to the lateral pterygoid, a muscle of mastication. This follows from the trigeminal (V3) supplying all muscles of mastication and the facial (VII) supplying all muscles of facial expression.
