Document Summary
Cranial bones (8) (neurocranium) tend to be flat of armor, mainly protection houses the brain. Anatomy 3319: parietal (2, temporal (2, frontal, ethmoid, occipital, sphenoid. Facial bones (14) (viscerocranium) tend to define sensory organs (eyes, nose, ear, mouth) form the face: maxillae (2, zygomatic (2, nasal (2, lacrimal (2, palatine, vomer, mandible. Intraorbital foramen v2 maxillary division of cn5. Maxilla comes together and fuse down the midline. Resembles a bat: greater and lesser wings. Sella turcica: resembles a saddle: has a depression called the pituitary fossa: where the pituitary gland is, sits in the fossa. Some venous drainage on either side of the pituitary gland: the cavernous sinus. If there was a pituitary tumor (cannot grow forward and backward) so start to affect the cavernous sinus. Superior orbital fissure: long gash like opening toward the orbit: several nerves controlling the eye pass through here. Optic canal: where the optic nerve passes through to the orbit.
