Answers
Answer:
The skeletal system is divided into two parts: the axial skeleton and appendicular skeleton. The axial skeleton includes the skull, spinal column, ribs and sternum. The appendicular skeleton includes all upper and lower extremities, the shoulder girdle and the pelvic girdle. Bones in the human body come in four main shapes, long, short, flat and irregular and are composed of webs of collagen fibers reinforced with calcium and phosphorous.
The collagen provides flexibility while the minerals provide tensile strength. There are 5 functions of the skeletal system in the body, three of which are external and visible to the naked eye, and two of which are internal. The external functions are: structure, movement and protection. The internal functions are: blood cell production and storage.
