  2. Pterygoid fossa - Wikipedia

    en.wikipedia.org/wiki/Pterygoid_fossa

    The lateral and medial pterygoid plates (of the pterygoid process of the sphenoid bone) diverge behind and enclose between them a V-shaped fossa, the pterygoid fossa. This fossa faces posteriorly, and contains the medial pterygoid muscle and the tensor veli palatini muscle.

  3. Pterygoid processes of the sphenoid - Wikipedia

    en.wikipedia.org/wiki/Pterygoid_processes_of_the...

    The lateral pterygoid plate of the sphenoid (or lateral lamina of pterygoid process) is broad, thin, and everted and forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone, and serves as the origin of the lateral pterygoid muscle, which functions in allowing the mandible to move in a lateral and medial direction, or from side-to-side.

  4. 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.

  5. 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.

  6. Pterygoid canal - Wikipedia

    en.wikipedia.org/wiki/Pterygoid_canal

    The pterygoid canal (also vidian canal) is a passage in the sphenoid bone of the skull leading from just anterior to the foramen lacerum in the middle cranial fossa to the pterygopalatine fossa. [ 1 ]

  7. Greater wing of sphenoid bone - Wikipedia

    en.wikipedia.org/wiki/Greater_wing_of_sphenoid_bone

    The greater wings of the sphenoid are two strong processes of bone, which arise from the sides of the body, and are curved upward, laterally, and backward; the posterior part of each projects as a triangular process that fits into the angle between the squamous and the petrous part of the temporal bone and presents at its apex a downward-directed process, the spine of sphenoid bone.

  8. Infratemporal space - Wikipedia

    en.wikipedia.org/wiki/Infratemporal_space

    It is located posterior to the maxilla, between the lateral pterygoid plate of the sphenoid bone medially and by the base of skull superiorly. [2] The term is derived from infra- meaning below and temporal which refers to the temporalis muscle .

  9. Tensor veli palatini muscle - Wikipedia

    en.wikipedia.org/wiki/Tensor_veli_palatini_muscle

    It arises from the scaphoid fossa of the pterygoid process of the sphenoid [1] anteriorly [citation needed], the (medial aspect of the) spine of sphenoid bone posteriorly, and - between the aforementioned anterior and posterior attachments - from the anterolateral aspect of the membranous wall of the pharyngotympanic tube.
