What is the skeletal system? Explain.

(N/A) $\Rightarrow$ The hard,supporting,and protective component of an animal body forms the skeleton or skeletal system.
$\Rightarrow$ The study of the skeletal system is known as $\text{Osteology}$. The skeletal system is composed of bones and a few cartilages.
$\Rightarrow$ It plays a significant role in the movement exhibited by the body.
$\Rightarrow$ Bone and cartilage are specialized types of connective tissue.
- Bone has a very hard matrix due to the presence of calcium salts,whereas cartilage has a slightly pliable matrix due to chondroitin salts.
In human beings,this system consists of $206$ bones and a few cartilages.
It is categorized into two principal divisions: $(i)$ the $\text{axial}$ skeleton and $(ii)$ the $\text{appendicular}$ skeleton.
