Skeletal System In the human being, the skeletal system is consist of a framework of bones and cartilage which provide protection to the soft tissues and cell that is embedded in our body. In an adult, human, have a total number of 206 bones found in ts body. There are two types of Skeletal systems found in the human body known as endoskeleton and exoskeleton . The exoskeleton is ectodermal in origin formed outside the body and is non-living whereas endoskeleton is mesodermal in origin formed inside the body and it is living by nature.
