The buccal branch is a nerve branch of the facial nerve (cranial nerve VII) responsible for innervating the muscles of facial expression in the cheek area. This branch plays a crucial role in the movement of facial muscles, contributing to expressions such as smiling and frowning.

Buccal Branch

Nerve branch

The facial nerve, also known as cranial nerve VII, is a mixed nerve responsible for motor control of facial muscles, taste sensations from the anterior two-thirds of the tongue, and various autonomic functions such as salivation and tear production. Damage to this nerve can result in conditions like Bell's palsy, characterized by facial muscle paralysis on one side.

Facial Nerve

Cranial Nerve VII, also known as the Facial Nerve, is primarily responsible for innervating the muscles of facial expression and conveying taste sensations from the anterior two-thirds of the tongue. It also plays a role in the production of saliva and tears, as well as transmitting sensory information from a small area around the ear.

Cranial Nerve VII

The muscles of facial expression are a group of muscles that originate from the bones of the face or fascia and insert into the skin, allowing for the wide range of facial expressions that convey emotions. These muscles are innervated by the facial nerve (cranial nerve VII), highlighting their importance in non-verbal communication and emotional expression.
