Anatomy and physiology assignment:

The human skeleton is an amazing and complex structure. There are over 270 bones in the body at birth, but after a few years it shrinks to 206 when some bones fuse together. Example: The bones in the cranium (skull). (en.wikipedia.org/wiki/Human_skeleton)
The human skeleton is split into two parts: Axial and appendicular skeleton.
Axial skeleton:
The axial skeleton consists of the cranium, vertebral column, ribs, and sternum. The axial skeleton has 80 bones and forms the longitudinal axis of the body. (hawaii.hawaii.edu/brashear/A&%20P%20ch7.pptm) Appendicular skeleton:
The appendicular skeleton consists of the other 126 bones which bring the total up to 206. It involves the Pelvic and Pectoral girdles and all attached limbs (arms …show more content…
These joints include:
• Fibrous (immoveable)
• Cartilaginous (slightly moveable)
• Synovial (freely moveable)
Fibrous:
The fibrous joint is immoveable. Fibrous joints are joints which are held together by fibrous connective tissue. An example of a fibrous joint is the cranium. Fibrous joints are split up into sutures, syndesmoses, and gomphoses. A suture is an immovable joint attaching certain bones of the cranium. A syndesmoses is an immoveable joint which is neither a suture nor a gomphoses. A gomphoses is an immoveable joint in the shape of a socket at which one structure in the body is attached to another. Example = Cranium.

Cartilaginous:
There are two types of cartilaginous joints in the body:
1. Synchondroses
2. Symphyses
A synchondroses joint is an immoveable joint in which the material connecting the two surfaces is cartilage. A symphyses is a slightly moveable joint in which the surfaces of the bones are covered with cartilage and the bones are attached together by discs. Example = Vertebral column.

HW Human Evolution 8/1/15 Human Evolution has spanned approximately 85 million years, but Homo sapiens have only existed for the last 400,000 years.
