Several nerves work together to control the movement and sensation in your lips. While a complete list requires more comprehensive neurological information, one key nerve branch is the buccal branch.
The Role of the Buccal Branch
The buccal branch of a nerve plays a significant role in controlling the upper lip. Specifically, the buccal branch is responsible for:
- Upper lip movement.
- Raising the corner of your mouth to smile.
- Sending information to muscles that control your nostrils.
- Spontaneous blinking.
