The sphenoid bone is a complex bone located at the base of the skull, forming part of the cranium that encloses the brain. In humans, it is present in embryos and later fuses with other parts of the skull. The sphenoid bone contributes to the cranial floor and articulates with several other cranial bones, including the frontal, parietal, temporal, and occipital bones.
