Document Summary
The skull cranial bones: frontal bone (1, supraorbital margin, supraorbital notch, parietal bones (2, superior and inferior temporal lines, temporal bones (2, styloid process, mastoid process, zygomatic process, mandibular fossa, external auditory meatus. The skull facial bones: nasal (2, maxillae (2) infraorbital foramen, palatine process, lacrimal (2, zygomatic (2) temporal process, vomer (1, mandible (1, mental foramen, condylar process, coronoid process, palatine (2, superior, middle and inferior nasal conchae (2) Cranial meninges: dura mater, external, arachnoid mater, middle, pia mater. Innermost: attached to outer layer of brain. Ventricular system: lateral ventricles, behind fornix, 3rd ventricle, around thalamus, 4th ventricle in cerebral aqueduct. Structural features cerebrum: gyri: upper folds, sulci: grooves, fissure: deep groove, central sulcus: deep sulcus dividing l & r hemispheres, lobes, frontal, parietal, occipital, temporal, corpus callosum: connects r & l hemispheres. Structural features cerebellum: folia: ridges, vermis: connects r & l hemispheres, primary fissure: separates anterior & posterior lobes.
