Disorders of the posterior labial commissure can affect the area where the upper and lower lips meet towards the back. These conditions can impact daily activities like eating, speaking, and facial expressions. Understanding these disorders helps in early detection and effective management.
The posterior labial commissure is the junction where the upper and lower lips meet near the back of the mouth, close to the corners of the mouth. This area is crucial for functions like sealing the mouth, speech articulation, and facial expressions.
Pathophysiology
Structure
The posterior labial commissure consists of:
- Skin and Mucosa: Covers the external and internal surfaces.
- Muscles: Small muscles control lip movements.
- Connective Tissue: Provides support and flexibility.
Blood Supply
Blood reaches this area primarily through:
- Superior Labial Artery: Supplies the upper lip.
- Inferior Labial Artery: Supplies the lower lip.
Nerve Supply
Nerve signals are provided by:
- Facial Nerve (VII): Controls muscle movements.
- Trigeminal Nerve (V): Provides sensation.
