Questions: Question 3 What is the difference between the bones of the cranium and the facial bones?

The bones of the cranium and the facial bones serve different functions and are located in distinct areas of the skull.

1. Cranial Bones:

   • The primary function of the cranial bones is to protect the brain.
   • They form the cranial cavity, which houses and safeguards the brain.
   • There are eight cranial bones: the frontal bone, two parietal bones, two temporal bones, the occipital bone, the sphenoid bone, and the ethmoid bone.
   • These bones are generally thicker and more robust to provide protection.

2. Facial Bones:

   • The facial bones primarily support the structures of the face and provide cavities for the sense organs (eyes, nose, and mouth).
   • They also provide attachment points for facial muscles, which are important for expressions and mastication (chewing).
   • There are fourteen facial bones: two nasal bones, two maxillae, two zygomatic bones, the mandible, two lacrimal bones, two palatine bones, two inferior nasal conchae, and the vomer.
   • These bones are generally more delicate and varied in shape to accommodate the complex structures of the face.

In summary, the main difference lies in their functions and locations: cranial bones protect the brain, while facial bones form the structure of the face and support sensory functions.
