Learn about the sphenoid bone definition, where is it located in the skull, along with its anatomy, parts, markings, and what it does, with labeled diagram.
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.
The sphenoid bone is one of the most complex bones of the human body. Due to its shape, it is also referred to as the 'wasp bone'. It makes up most of the middle part of the base of the skull and contributes to the floor of the middle cranial fossa of the skull.
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 bone (wasp bone) is part of the base of the skull. An unpaired bone located in the cranium (or skull), the sphenoid bone, also known as the “wasp bone,” is located in the middle and toward the front of the skull, in front of the occipital bone and behind the frontal bone.
Explore the anatomy and structure of the sphenoid bone with Innerbody's interactive 3D model. The sphenoid bone is wedged between several other bones in the front of the cranium. It consists of a central part and two wing-like structures that extend sideways toward each side of the skull.
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 (also called the sphenoid, sphenoidal bone, Latin: os sphenoidale) is a single bone that lies in the base of the skull between the frontal, temporal and occipital bones.
Sphenoid bone is a butterfly-shaped cranial bone that is located in the middle of the skull between the frontal and temporal bones.
Introduction. 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.
