The head is a protective capsule enveloping the brain. It is balanced so well that relatively little muscle power is required to move it. The two large sections of the skull are the brain case and the facial skeleton. The brain case is egg-shaped, with a ‘pointed’ pole at the forehead, a broad and blunt occipital region, tilted backwards and downwards through its vertical axis that runs from the supraorbital ridge through the external acoustic meatus, and enclosed by the following zones: the forehead to the temple; crown–occipital region; external base of cranium.
The facial skeleton, which forms the internal supporting scaffold for the face – with the exception of the ancillary shapes – forms a vertical bow that is delimited by the supraorbital ridge at the top, the mental protuberance at the bottom and the mandibular fossa at the back
