Synonyms: none 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.

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.

greater wing of sphenoid (bone): [TA] strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these surfaces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portion of the middle cranial fossa; 2) temporal surface: forms the deepest portion.
Greater Wing Of Sphenoid slidesharedocs
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

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 Sphenoid bone (os sphenoidale; Gr., sphen - wedge + eidos - form) is a butterfly-shaped cranial bone that is located in the middle of the skull between the frontal and temporal bones.. Sphenoid bone primarily consists of a centrally positioned body, which surrounds and protects the pituitary gland, and two sets of lateral, wing-like extensions called the greater and lesser wings.

easyhumanatomy Sphenoid easy and brief discussion
The greater wings of the sphenoid bone (GWS) are the components of the sphenoid bone that project laterally from the central body and form the anterior and medial portions of the floor of the middle cranial fossa. Many skull base foramina in the GWS transit important neurovascular structures.

Greater Wings Emerging behind the lesser wings and also running to the sides are the two greater wings, which are also triangular and run lateral to the body. Their sides make up the infratemporal surfaces, which are convex in shape, and move backward and to the sides.

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.
