Mandibular nerve

mandibular divisionmandibular division of the trigeminal nervemandibular
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 teeth.
The anterior division gives off branches to three major muscles of mastication and a buccal branch which is sensory to the cheek.

Cheek

buccalmalarcheeks
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 teeth.
In humans, the region is innervated by the buccal nerve.

Inferior alveolar nerve anaesthesia

inferior alveolar nerve blockInferior alveolar nerveMandibular block
A buccal nerve block is carried out after an inferior alveolar nerve block for specific procedures, such as extraction of mandibular molar teeth.
However, depending on technique, the long buccal nerve may not be anesthetized by an IANB and therefore an area of buccal gingiva adjacent to the lower posterior teeth will retain normal sensation unless that nerve is anesthetized separately, via a (long) buccal nerve block.

Buccal branches of the facial nerve

Buccal branch of the facial nerveBuccal branchbuccal branches
Not to be confused with the buccal branch of the facial nerve which transmits motor information to the buccinator muscle. 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 branches of the facial nerve on the surface of the buccinator muscle. The facial nerve (CN VII) also has buccal branches, which carry motor innervation to the buccinator muscle, a muscle of facial expression.
The lower deep branches supply the buccinator and orbicularis oris, and join with filaments of the buccinator branch of the mandibular nerve.
