Normal Anatomy The sphenoid bone forms the central skull base and viewed anteriorly resembles a bird with its wings unfurled. It is a compound bone with a median body and paired lateral greater and lesser wings ( Fig. 3.1 ).
Sphenoid Bone
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. Its name derives from the Greek 'sphenoeides,' which means wedge-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. The sphenoid bone has a central body, and paired greater and lesser wings that extend laterally from the body of the sphenoid.

The greater wings of the sphenoid bone (GWS) comprise the com-ponents of the sphenoid bone that make up most of the posterior orbital wall and form the anterior and medial parts of the floor of the middle cranial fossa. Many important skull base foramina, which transmit vital neurovascular structures, are present in these paired wings on either.

The greater wing of the sphenoid bone also forms the anterior margin of the foramen lacerum, which is filled with cartilage during life. Anterior to the greater wing of the sphenoid is the lesser wing of the sphenoid bone. This shelf of bone forms the posterior part of the anterior cranial fossa and extends laterally, and articulates.

The greater wing of the sphenoid is a bony projection arising from both sides of the sphenoid body forming a part of the floor of the middle cranial fossa. Jakob Benignus Winslow coined the term foramen spinosum because of the foramen's location in the spinous process of the greater wing of the sphenoid. [1] Go to: Structure and Function
