Question

Most of the cartilages in vertebrate embryo are replaced in adult by

• A. Blood
• B. Bones
• C. Tendons
• D. Ligaments Muscle

Answer 1

The correct option is B Bones

• Endochondral ossification is the process by which growing cartilage is systematically replaced by bone to form the growing skeleton in vertebrate embryo.
  
• This process occurs at three main sites: the physis, the epiphysis, and the cuboidal bones of the carpus and tarsus.
  
• It is the mechanism responsible for the formation of all long bones of the axial skeleton (vertebrae and ribs) and the appendicular skeleton (limbs).
  

So, the correct option is 'Bones'.
