The Important Role of Skull AnatomyCredit: http://www.chiropractictools.com/skull_model.php
The skull anatomy is one of the most important structures of the body. It gives our head form, shape, and size. The skull is basically designed to protect the most vital organ of our body which is the brain. Without the skull, our brain and other adjacent structures would be exposed to risk factors that might be detrimental to our health. The skull should be given a good look to better appreciate it.
Overview of the Skull Anatomy
The skull anatomy has many functions aside from protecting the brain. It serves aesthetic purposes since it provides the visible appearance of the face. The cranium is the part of the skull where it holds the brain. While the skull has many bones, the following list is located at the face.

Single Cranial BonesCredit: http://www.hscripts.com/freeimages/icons/human/skull-frontal-bone.php
Frontal bone is located at the front of the skull anatomy and is the most important cranial bone because it holds the eyeballs and gives the face its appearance. It has two parts; the horizontal portion (pars orbitals) and the vertical portion (squama frontalis).
Ethmoid bone is made up mostly of spongy bone that forms the structure that supports the eye socket and the top of the nose. It is cubical in shape and protects the internal regions of the nose and eyes.
Sphenoid bone is made up of 6 portions which are the pterygoid processes, lesser wings (2), greater wings (2), and body of the bone. The sphenoid bone resembles closely the shape of a butterfly or a winged creature. It is located at the anterior part of the temporal bone and forms part of the eye socket.
Occipital bone is very vital in protecting the optic nerves and the eyes though it is located at the back of the head. It is essential for the support and movement of the head. The occipital bone has a gap where it allows the skull to be connected with the spinal column. There are three regions in which the occipital bone is subdivided. These are the lateral part, basilar part, and the squama occipitalis.
Paired Cranial BonesCredit: http://bodyquiz.net/human-body/_design/main/_show/bones/en-bones-parietal_bone
Parietal bones form part of the upper and lateral sides of the cranium. It is very important for the protection of the brain. The parietal bone has four borders known as the occipital, frontal, squamous, and sagittal border.
Temporal bones form part of the lateral and lower sides of the cranium. The temporal bones protect the temples and have four different portions called the tympanic, mastoid, petrous, and squama temporalis.
Summary of the Skull Anatomy
The skull anatomy is truly a magnificent structure. It serves many functions and purposes which include protection of the vital organs, compartment for the eyes and nose, and appearance of the face.
