ANATOMY

Detailed explanation-1: -The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible.

Detailed explanation-2: -Most of the bones in the animal body have both types, the dense compact bone forming an outer shell surrounding a core spongy cancellous bone. In this configuration the bone forms a sandwich structure similar to man made sandwich structures of fiber glass faces separated by a foam core.

Detailed explanation-3: -The cranium is composed of eight bones: the paired parietal and temporal bones, and the singular frontal, ethmoid, sphenoid, and occipital bones. These bones protect the brain and the special sense structures related to hearing, balance, smell, and vision.

Detailed explanation-4: -The human cranium, the part that contains the brain, is globular and relatively large in comparison with the face. In most other animals the facial portion of the skull, including the upper teeth and the nose, is larger than the cranium.

Detailed explanation-5: -In addition to teeth, other skull structures can tell you whether an animal is a meat-or plant-eater. For example, there are numerous sites on the skull for muscle attachment, which vary from species to species. In carnivores and omnivores, there is a ridge on top of the skull called a sagittal crest.
