The skull bones, comprising 22 bones collectively known as crania, form the bony framework of the cranium, protecting the delicate brain within. These bones exhibit a remarkable range of shapes and sizes, each playing a specific role in facial movement, breathing, and the overall structure of the face.
The skull bones exhibit remarkable flexibility and can adapt to different facial expressions and expressions of emotions. The facial bones, including the eye orbits, nose, and mouth, move independently to ensure that facial muscles and expressions are executed correctly.
The skull bones are categorized into two main groups: the axial skeleton and the facial skeleton. The axial skeleton consists of 14 bones that are arranged in a symmetrical sagittal plane. These bones are primarily responsible for the structural integrity of the cranium and contribute to facial symmetry.
The facial skeleton comprises eight bones located in the upper and lower face. These bones are responsible for facial expressions, breathing, and the movement of the tongue. Examples of facial bones include the cranium, zygomatic bones, cheekbones, and nose.
The skull bones are also innervated by the facial nerve, which provides sensation to the face and helps regulate facial movements. The facial nerve originates from the trigeminal nerve and also supplies sensory information to the eyes.
The skull bones have evolved over millions of years, demonstrating remarkable resilience and adaptation. They continue to undergo changes and adaptations throughout life, including growth and development, until the age of approximately 25
