The human skull is the bony structure that forms the head in the human skeleton. It is formed by the bones of neurocranium and the bones of viscerocranium. The skull protects the encephalon and the sense organs.
The human skull is the bony structure that forms the head in the human skeleton. It is formed by the bones of neurocranium and the bones of viscerocranium. The skull protects the encephalon and the sense organs. Among the 28 organs that made the skull only the jaw is mobile. Some bones are paired which means there is one bone on each side of the skull.
In the human skull we find the following bones:
-Frontal bone: it is an unpaired bone that rests upon the parietal bones and is articulated with the great wing of the sphenoid.
-Temporal bone: it is a paired bone located at the sides and base of the skull.
-Occipital bone: it is a paired bone located at the back and lower part of the skull.
-Parietal bone: it is a paired bone that forms the sides and roof of the cranium.
-Ethmoid bone: it is an unpaired bone that separates the nasal cavity from the brain. It is located at the roof of the nose between the two orbits.
-Sphenoid bone: it is an unpaired bone that is located in the middle of the skull towards the front.
-Ossicles: malleus, incus, stapes.
Throughout history, skulls have been used as a symbol of death and mortality in different cultures. Skulls have been present as a cultural symbol, from the ancient rituals in primitive societies to modern art, from Shakespeare’s Hamlet to Claesz’s pictures, even hidden in Gilbert or Dali’s pictures. We also find them in street graffiti or tattoos.
Pirates used skulls as a symbol of death danger, combined with two crossed tibiae on a black background. Each pirate had his own flag, but skulls and bones were present in most of them. Nowadays a skull still is a warning symbol that invites people to stay away. You will never drink from a bottle with that symbol, will you? It is a symbol that we instinctively reject: it is the face of death. The meaning of the skull is related to bones without flesh, and flesh is life. A skull is thus a structure that contained life in the past.
What we cannot deny is the beauty and visual appeal of skulls. Humans usually recognize fragments of an only partially revealed cranium. We could say that together with death the skull represents our mortal condition and the fragile condition of human beings. The skull has been used in fact as a symbol of mortality in the sense of the Latin proverb ‘Memento mori’
