The bones in our cranium

lets know much about skull:
The cranium is that part of the skull that holds and protects the brain in a large cavity, called the cranial vault. Eight plate-like bones form the human cranium by fitting together at joints called sutures. The most important of these cranial bones for the appearance of the face is the frontal bone, which underlies the top of the face above the eyeballs. The human skull also includes 14 facial bones that form the lower front of the skull and provide the framework for most of the face that is important to psychological research. These 22 skull bones form other, smaller cavities besides the cranial vault, including those for the eyes, the internal ear, the nose, and the mouth. The important facial bones include the jaw bone or mandible, the maxilla or upper jaw, the zygomatic or cheek bone, and the nasal bone.
The skull bones are associated with many other features. Processes are areas where the bones have extra tissue to hold muscles and ligaments; lines are grooves in the bone from other developmental processes; foramina are holes in the bones through which nerves and blood vessels pass; sinuses are empty spaces in the bones that make the skull lighter. Some of these features affect the physiognomy of the face due to variations in thickness, size, location, and shape.

The cranium (general)

The Cranium, also called the "Skull," describes the skeleton of the head, face and mandible.
It is a portion of the axial skeleton, or that portion associated with the central nervous system. Those portions of the skeleton not associated with the central nervous system, are associated with the appendicular skeleton or the extremities (i.e., the arms and legs).
The axial skeleton consists of the cranium, all the osseous elements of the vertebral column, the ribs, and the sternum.
In an adult, various of the bones of the cranium are paired left and a right, while others, which cross the mid-sagittal plane, are unpaired. Furthermore, the bones of the skull are classified as those which are called Cranial Bones, or contribute to that portion surrounding the brain, or Facial Bones(i.e., those which do not assist in forming the braincase).
Each of the bones of the cranium posses a number of distinctive features which not only allow the bone to be identified, but also permit its exact location and orientation in the body to be determined (i.e., as a left or right, medial- lateral, posterior-anterior, inferior-superior, etc.).

Hello everyone
in this blog i wanna share my idea's ,studings and every thing i know about physical anthropology,so you can use it. first of all i will start ith Anatomy and related body science which is very useful for being a good physical anthropology
my favorite part in hole of this field is evolution and then Homo Floresiensis.
i will also try my best to link best physical anthropology sites.
well done
