The cheek bone is scientifically known as the zygomatic bone.
These prominent facial bones are widely recognized as the cheekbones, forming a key part of your facial structure and contributing significantly to your overall appearance.
The Zygomatic Bones Explained
The zygomatic bones are crucial for the structure and function of the face, playing roles in protection, muscle attachment, and facial aesthetics.
Anatomy and Location
The zygomatic bones are a pair of irregular bones situated in the cranium. Each zygomatic bone:
- Forms the noticeable prominence of the cheek, which gives the face its contour.
- Contributes to the lateral wall and a portion of the floor of the orbit (the bony socket that houses the eyeball).
- Forms part of the zygomatic arch, a bridge-like structure that extends towards the ear.
These bones articulate (join) with several other significant bones of the skull, including:
- The frontal bone (forehead)
- The maxilla (upper jaw bone)
- The sphenoid bone (a complex bone located at the base of the skull)
- The temporal bone (side of the head, forming the other part of the zygomatic arch)
Function and Importance
Beyond their aesthetic contribution, the zygomatic bones serve several vital functions:
- Structural Support: They provide the essential framework for the cheeks and the lower part of the eye socket, offering crucial protection to the delicate eyes from potential impact.
- Muscle Attachment: The zygomatic bones act as strong anchor points for various facial muscles. This includes muscles of mastication (chewing), such as the masseter muscle, and muscles responsible for dynamic facial expressions like smiling.
- Protection: Their robust and strategically placed structure helps shield delicate cranial and orbital contents from injury.
Common Issues and Care
Due to their prominent and exposed position, zygomatic bones can be susceptible to injury, particularly from facial trauma. Fractures of the zygomatic bone, often referred to as zygomaticomaxillary complex (ZMC) fractures, can potentially impact vision, affect the ability to chew properly, and alter facial sensation. Maintaining strong bones through adequate intake of essential nutrients like calcium and vitamin D is beneficial for overall skeletal health, including the bones of the face.
