Study Notes

Cranial Sutures

Coronal suture: Connects the frontal bone to the parietal bones.
Sagittal suture: Links the two paired parietal bones together.
Lambdoidal suture: Joins the occipital bone with the paired parietal bones.
Squamosal suture: Connects the temporal bones to the parietal bones.

Specific Facial Sutures

Temporozygomatic suture: Forms between the temporal process of the zygomatic bone and the zygomatic process of the temporal bone.
Median palatine suture: Connects the two palatine processes of the maxilla anteriorly with the two horizontal plates of the palatine bones posteriorly.
Transverse palatine suture: Articulates the two palatine processes of the maxillae with the two horizontal plates of the palatine bones.

Key Bone Structures

Significant bone structures include the styloid process, external oblique line, angle of mandible, hyoid bone, mandibular condyle, vertebra, coronoid process, pterygoid plates, ear lobe, mandibular canal, and mental foramen.

Orbit of the Eye

The orbit is formed by the following bones: orbital plates of the frontal bone, ethmoid bone, lacrimal bone, zygomatic bone, and the orbital surface of the greater wing of the sphenoid bone.

Temporal Fossa Components

Comprised of five bones: zygomatic, frontal, greater wing of sphenoid, temporal, and parietal bones.

Infratemporal Fossa

Contains the mandibular division of cranial nerve V (trigeminal nerve) which enters via foramen ovale.
Includes inferior alveolar and lingual nerves, pterygoid plexus, and the pterygoid muscles.

Pterygopalatine Fossa

Houses the maxillary nerve and artery, infraorbital and sphenopalatine arteries, along with the maxillary division of cranial nerve V entering through foramen rotundum and the pterygopalatine ganglion.
