  2. Sphenoid bone - Wikipedia

    en.wikipedia.org/wiki/Sphenoid_bone

    The sphenoid bone [note 1] is an unpaired bone of the neurocranium. 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, bat or wasp with its wings extended.

  3. Body of sphenoid bone - Wikipedia

    en.wikipedia.org/wiki/Body_of_sphenoid_bone

    The lateral surfaces of the body are united with the greater wings of the sphenoid and the medial pterygoid plates.. Above the attachment of each greater wing is a broad groove, curved something like the italic letter f; it lodges the internal carotid artery and the cavernous sinus, and is named the carotid sulcus.

  4. Facial skeleton - Wikipedia

    en.wikipedia.org/wiki/Facial_skeleton

    The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium.. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.

  5. Chiasmatic groove - Wikipedia

    en.wikipedia.org/wiki/Chiasmatic_groove

    Anatomical terms of bone [ edit on Wikidata ] The chiasmatic groove ( chiasmatic sulcus , optic groove , prechiasmatic sulcus ) is a transverse [ 1 ] groove upon the superior aspect of the body of sphenoid bone [ 1 ] [ 2 ] : 509 within the middle cranial fossa .

  6. Pterion - Wikipedia

    en.wikipedia.org/wiki/Pterion

    The pterion is the region where the frontal, parietal, temporal, and sphenoid bones join. [1] It is located on the side of the skull, just behind the temple.It is also considered to be the weakest part of the skull, which makes it clinically significant, as if there is a fracture around the pterion it could be accompanied by an epidural hematoma.

  7. Foramen spinosum - Wikipedia

    en.wikipedia.org/wiki/Foramen_spinosum

    The foramen spinosum is a small open hole in the greater wing of the sphenoid bone that gives passage to the middle meningeal artery and vein, and the meningeal branch of the mandibular nerve (sometimes it passes through the foramen ovale instead).

  8. Sphenoidal lingula - Wikipedia

    en.wikipedia.org/wiki/Sphenoidal_lingula

    Anatomical terms of bone [ edit on Wikidata ] Along the posterior part of the lateral margin of the carotid groove of the sphenoid bone , in the angle between the body and great wing , is a ridge of bone, called the lingula .

  9. Foramen ovale (skull) - Wikipedia

    en.wikipedia.org/wiki/Foramen_ovale_(skull)

    The foramen ovale is an opening in the greater wing of the sphenoid bone. [1] The foramen ovale is one of two cranial foramina in the greater wing, the other being the foramen spinosum. [2]: 771 The foramen ovale is posterolateral to the foramen rotundum and anteromedial to the foramen spinosum.
