Answer; A. Facial artery
The muscle marked by black arrow represents the masseter muscle.
- The facial artery runs part of its course in the neck, and passes through the submandibular region before entering the face.
- When a person clenches his teeth, this makes the masseter prominent and its anterior border can be felt.
- The facial artery enters the face where the anterior border of the masseter cuts the lower border of the mandible. The pulsations can be felt there.
