As we all remember from that time we took two hours to dig up the Reelz channel on our programming guide, Katie Holmes played Jackie opposite Greg Kinnear in the Kennedys miniseries. I actually thought she did a smooth job of it, especially whenever fixing people with a knowing, aristocratic gaze.
Meninges. Apart from the scalp and skull there are three other layers inside the skull that encase and protect your brain. These coverings together are the meninges, and consist of the Dura Mater, the Arachnoid, and the Pia Mater.
A) The Neurocranium (Chondrocranium). The neurocranium is the portion of the skull that protects the brain and certain sense organs. In the Elasmobranchs (sharks and rays) it is composed of cartilage (chondrocranium), but in most other vertebrates, the cartilage is replaced by bone (endochondral or replacement bone).he dermatocranium forms most of the skull and functions as a protective shield for the brain. See the dermal armour of Amia, the bowfin, which sits on the cartilaginous neurocranium. In other animal groups the cartilage disappears and when you look down on the skull you are looking at the bones of the dermatocranium.
