The buccal nerve (long buccal nerve) is a sensory nerve of the face arising from the mandibular nerve (CN V3) (which is itself a branch of the trigeminal nerve).It conveys sensory information from the skin of the cheek, and parts of the oral mucosa, periodontium, and gingiva.
The buccal branches of the facial nerve ... and join with filaments of the buccinator branch of the mandibular nerve. Muscles of facial expression ...
The mandibular nerve gives off the following branches: From the main trunk (before the division): meningeal branch (nervus spinosus) (sensory) medial pterygoid nerve (motor) From the anterior division: masseteric nerve (mixed) deep temporal nerves (mixed) buccal nerve (sensory) lateral pterygoid nerve (motor) From the posterior division:
The nerve then bifurcates at the pes anserinus to become the upper and lower divisions of the facial nerve. [4] It then splits into five branches (temporal, zygomatic, buccal, marginal mandibular and cervical), innervating the muscles of facial expression. [5] [6]
The inferior alveolar nerve is a branch of the mandibular nerve, the third division of the trigeminal nerve. This procedure attempts to anaesthetise the inferior alveolar nerve prior to it entering the mandibular foramen on the medial surface of the mandibular ramus. [citation needed]
The 42nd edition of Gray's Anatomy (2020) describes a parotid-masseteric fascia as a thin and translucent yet tough fascia that covers the parotid duct, buccal branches of facial nerve (CN VII), and branches of the mandibular nerve where these structures lie upon the surface of the masseter muscle.
There are usually two deep temporal nerves - the anterior deep temporal nerve and posterior deep temporal nerve. Occasionally, a third one is present - the middle deep temporal nerve. [2] Origin. The anterior one may arise from the buccal nerve, and the posterior one may arise from the masseteric nerve. [2]
This is a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). [1] It emerges from the mental foramen in the mandible. [2] It divides into three branches beneath the depressor anguli oris muscle. One branch descends to the skin of the chin. Two branches ascend to the skin and mucous membrane of the lower lip.
