Included in the middle cranial fossa, the sphenoid is a morphologically similar bone to a butterfly, on which at least 6 characteristic elements are recognizable, which are: the sphenoid body, the two major wings, the two minor wings and the two pterygoid processes.
The sphenoid is an important bone, because: it helps to form the lateral wall of the skull and the floor on which the brain rests; it is the seat of attachment for important chewing muscles; forms the posterolateral walls of the eye sockets and the posterior walls of the nasal cavities; finally, through a series of holes and channels on its surface, it is the passageway for the nerves and blood vessels of the head and neck.

of the so-called neurocranium (or cranium), that is the superior skeletal complex of the skull, within which the brain is enclosed.
A fundamental component of the so-called floor of the skull (or base of the skull), the sphenoid is an unequal bone (therefore it is a unique element), with a very complex shape.
