The Anatomy of the facial muscles

Let’s plunge into the anatomy of the facial muscles! And today, according to the plan, we have cheekbone muscles! Interesting? 👩‍🎓
In the area of the cheekbones are the small and large zygomatic muscles.
The main function is to move the corners of the mouth up and to the sides, forming a smile. 🙂
Both have a solid point of upper attachment — the zygomatic bone, with the other end they are attached to the skin of the corner of the mouth and the circular muscle of the mouth.
The small zygomatic muscle starts from the buccal surface of the zygomatic bone and attaches to the thickness of the nasolabial fold. Contracting, it raises the corner of the mouth, and changes the shape of the nasolabial fold itself.
The large zygomatic muscle is the main muscle of laughter. It attaches simultaneously to the zygomatic bone and to the zygomatic arch. The large zygomatic muscle pulls the corner of the mouth up and sideways, greatly deepening the nasolabial fold.
