Where is the base of the skull located?
The skull base is located at the base of the brain. It sits behind the eyes and above the nasal cavity—the large empty space behind the nose—and slopes down to the back of the head. It separates the brain from other structures of the head.
What are the three types of skulls?
Due to the difference in the cranial index, scientists classified the human skulls into 3 main types- Caucasoid(European), Mongoloid(Asian), Negroid(African).
What do most facial bones articulate with?
The paired nasal bones form the anterosuperior bony roof of the nasal cavity. They are approximately quadrangular. They articulate with the nasal process of the frontal bone superiorly, the frontal process of the maxillary bone laterally, and with one another medially.
What is the function of the lateral skull?
The posterior surface protects the region of the brain that contains the occipital lobes and cerebellum. The lateral bones include the temporal and zygomatic bones which encase the brain and provide attachment to the muscles of the face respectively.
