Just one. It's wedged between many bones in the skull in the center and spans the entire width, so in a diagram it may look as though there are two, one each making up part of the lateral aspect and the eye sockets, but it is really the two "wings" of the same bone.
These are bones of the skull, specifically in the region of the cranium. The occipital bone forms the back of the skull, the sphenoid bone is located at the base of the skull, the frontal bone forms the forehead, the temporal bone is located on the sides of the skull, and the ethmoid bone is located between the eyes.
The paired bones of the skull include the parietal, temporal, and zygomatic bones. These bones are present in pairs, with one on each side of the skull providing structural support and protection for the brain and sensory organs.
Sphenoid bone: A prominent, irregular, wedge-shaped bone at the base of the skull. The sphenoid bone has been called the "keystone" of the cranial floor since it is in contact with all of the other cranial bones.The Greek physician Galen wrote that the sphenoid bone was "like a wedge thrust between the skull and the superior maxilla."
The maxillae contain the maxillary sinuses, the ethmoid and sphenoid contain the ethmoid and sphenoid sinuses, respectively. ****Maxilla is a facial bone, the three cranial bones that contain sinuses are ethmoid, sphenoid and frontal.
The sphenoid bone is one of the skull bones and is located relatively deep within the skull. It is only very slightly visible from an exterior view of the skull. Looking side on to a skull it is right between the temporal bone and the zygomatic bone, in other words it is the small section beneath the Pterion. It is also visible when looking into the orbit (with the eye removed) as the bone with the superior orbital fissure through it.
The sphenoid, ethmoid, sacrum, coccyx, and mandible are all irregular bones.
Seven skull bones form the orbit: frontal, sphenoid, ethmoid, lacrimal, maxilla, palatine, and zygomatic.

There are 8 cranial bones in the human skull. They include the frontal bone, parietal bones, temporal bones, occipital bone, sphenoid bone, and ethmoid bone.
All bones of skull are flat bones,which are frontal,parietal,ocipital,temporal bones,sphenoid,ethmoid,zygomatic.
The paired bones of the skull include the parietal, temporal, and zygomatic bones. These bones are present in pairs, with one on each side of the skull providing structural support and protection for the brain and sensory organs.

The zygomatic bone is not part of the orbit of the skull. The orbit is made up of several bones including the frontal, ethmoid, lacrimal, sphenoid, maxilla, palatine, and zygomatic bones.
The greater wing is part of the sphenoid bone in the skull, forming a portion of the side of the skull and the floor of the cranial cavity. The lesser wing is also part of the sphenoid bone, located above the greater wing and forming a portion of the anterior cranial fossa.
