buccal branch of the facial nerve
The Buccal Branches of the facial nerve (infraorbital branches), of larger size than the rest of the branches, pass horizontally forward to be distributed below the orbit and around the mouth.
==Branches==
The ''superficial branches'' run beneath the skin and above the superficial muscles of the face, which they supply: some are distributed to the Procerus, joining at the medial angle of the orbit with the infratrochlear and nasociliary branches of the ophthalmic.
The ''deep branches'' pass beneath the Zygomaticus and the Quadratus labii superioris, supplying them and forming an infraorbital plexus with the infraorbital branch of the maxillary nerve. These branches also supply the small muscles of the nose.
The ''lower deep branches'' supply the Buccinator and Orbicularis oris, and join with filaments of the buccinator branch of the mandibular nerve.
