Key ideas in Bones of the Face and Body
- The mandible forms the lower jaw and chin
- Every other bone in the skull is locked in place except the mandible
- Chewing and speaking rely solely on the mandible hinged against the skull
- The zygomatic bone forms the high arch of the cheekbone
- The zygomatic bones form the outer and lower rim of the eye socket
- They connect the front of the face to the side of the skull
- The maxillae are two fused bones forming the central midface
- The maxillae secure the upper teeth and make up the floor of the nasal cavity
- The upper jaw does not move independently from the skull
- The frontal bone shapes the smooth curve of the forehead
- The thickened rim above the eyes acts like a built-in helmet visor protecting the eyeballs from top-down impacts
- It forms the upper roof of each eye socket
- Hollow sinus cavities keep the head light enough for neck muscles to hold up easily
- Air pockets act as echo chambers that give voice tone and resonance
- Solid bone throughout the face would make the front of the skull uncomfortably heavy
- The clavicle props the shoulder blade and arm out away from the rib cage like a rigid strut
