Question

Please help me discuss all three skulls and their respective parts SEPARATELY. Do NOT lump the ape and monkey together. Discuss each on its own. Separate discussions for each variety of (human, ape and monkey) and each element (mandible, maxilla, frontal, etc.) You can use any format (table, bullet points, paragraphs, etc). Need not worry about sounding hyper-intelligent. I am more interested in your observations.

Thank you very much.

Answer 1

In humans, apes (belongs to family Hominidae) and monkeys skull is a bony structure and forms head int the skeleton. in all these three organisms skull mainly forms the cavity of the brain and also protects from the injuries. the difference between skulls of these three organisms is the average human brain is about three times the size of the average chimpanzee brain. Compare with apes(chimpanzees, gorilla etc.,),monkeys, human skulls have a rounded brain case that is much larger. In monkeys skull has a large, doned cranium. The cranium protects the large brain it is the distinguishing feature of this group.

Humans, Apes and monkeys Mandible is developed into a lower jaw. It is also called Jaw bone. it is the largest and strongest bone in the facial bones. In Apes it is much larger and associated with a more primitive diet that is leaves and fibrous plants. In monkeys Mandible is covered with a avascular tissue that stretching from the surface to the underlying bone.

Maxilla is called upper jaw bone in all the three organisms (Humans,Apes,Monkeys). In humans maxilla consisting of following parts. those are

Frontal process

Zygomatic process

palatine process

alvelolar process

Forntal bone is one of the important bones of the skull structure. It consisting of two portions, vertically oriented squamous part and horizontally oriented orbital part. All the above give three organisms(Humans,Apes and Monkeys) frontal bone forms the fore head.
