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.

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.
Sphenoid Bone Location, Function, Anatomy, & Labeled Diagram
- 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.

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 or ali-sphenoid of the sphenoid bone is a process which projects from either side of the lower part of the sphenoid body, at a common junction with the pterygoid process 1 .
Sphenoid Bone
The greater wing of the sphenoid bone, or alisphenoid, is a bony process of the sphenoid bone, positioned in the skull behind each eye. There is one on each side, extending from the side of the body of the sphenoid and curving upward, laterally, and backward. Structure
Sphenoid bone anatomy, function, parts & sphenoid bone fracture
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 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.

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 ).

Functions It forms the base and lateral sides of the skull in combination with the orbital floor. 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.

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.
