What is "sphenoid bone"?

The sphenoid bone is a complex bone situated at the base of the skull, with a butterfly-like shape, forming part of the central skull and contributing to the cranial floor. The sphenoid bone houses various important structures, including the pituitary gland and several cranial nerves. It also serves as a connection point for other cranial bones and plays a crucial role in providing structural support for the skull and facilitating the proper functioning of the brain. Additionally, the sphenoid bone has openings that allow for the passage of blood vessels and nerves, contributing to the overall vascular and neural connectivity within the skull.
