● `color{brown}("Skeletal system")` consists of a framework of `color{brown}("bones")` and a `color{brown}("few cartilages.")`
● This system has a `color{violet}("significant role")` in movement shown by the `color{violet}("body.")`
● `color{violet}("Bone")` and `color{violet}("cartilage")` are `color{brown}("specialised connective tissues.")`
● The former has a very hard matrix due to `color{brown}("calcium salts")` in it and the latter has `color{violet}("slightly pliable matrix")` due to `color{brown}("chondroitin salts.")`
● In human beings, this system is made up of `color{brown}("206 bones")` and a `color{violet}("few cartilages.")`
● It is grouped into two principal divisions – the `color{brown}("axial")` and the `color{brown}("appendicular skeleton.")`
● `color{brown}("Axial skeleton")` comprises `color{brown}("80 bones")` distributed along the main `color{violet}("axis")` of the body.
● The `color{brown}("skull, vertebral column, sternum")` and `color{brown}("ribs")` constitute `color{violet}("axial skeleton.")`
