The main function of the sphenoid bone is to provide the foramina and canals for the passage of neurovascular structures to and from the cranium. In this article you will find out all about the anatomy of the sphenoid bone, its parts, borders, and development.
The sphenoid bone is one of the eight bones that make up the cranium – the superior aspect of the skull that encloses and protects the brain. Its name is derived from the Greek ‘sphenoeides’, to mean wedge-shaped.
Anatomy: Parts and Structure of the Sphenoid Bone. The sphenoid bone consists of a central body, with two lateral paired wings on either side – the lesser and greater wings – and two pterygoid processes. This unique anatomy gives the bone a prominent bat-, butterfly-, or wasp-like appearance.
The sphenoid bone is one of the seven bones that make up the orbit (the space that holds the eyeball), and helps make up the floor of the middle cranial fossa, the butterfly-shaped depression at the base of the skull that houses the temporal lobes of the cerebellum.
The sphenoid bone encompasses a central body, alongside two lateral paired wings on both sides – the lesser and greater wings – and two pterygoid processes. This distinctive structure gives the bone a noticeable bat-, butterfly-, or wasp-like appearance.
It is situated in the middle of the skull towards the front, in front of the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.
The sphenoid is just one of the twenty-two bones that form the skull and essentially helps to connect the neurocranium to the facial skeleton. It is a single bone in the midline of the cranial cavity situated posterior to the frontal bone but anterior to the occipital.
The sphenoid bone is a complex, sphenoid-shaped bone located in the middle of the skull, behind the nose and between the orbits (eye sockets). It forms the central part of the skull base and has numerous important attachments and functions.
The sphenoid bone of the skull base is one of the most complex bones of the body. It is an unpaired bone with many foramina (holes) and grooves that allow nerves and blood vessels to pass through or along it. The form of the sphenoid bone is often referred to as bat-shaped, wasp-shaped, or butterfly-shaped.
The sphenoid bone is located at the central skull base and is commonly considered the most complex bone in the human body. It forms the major boundary between the intra- and extracranial structures and is a conduit for several cranial nerves.
