Explanation / Answer

1. All the above- epiphyseal plates - It is the growth plate, made of cartilage which gradually ossifies; endochondral ossification - Involves calcification of cartilage matrix; external circumferential lamellae - lamellae wrapped around the long bone, binds osteons together; appositional growth - growth from outside cartilage forming cells, building onto existing cartilage making cartilage thicker.

2. 206 bones are present in adult human body

3. lamella - The concentric lamella forms a series of concentric rings resembling bull's eye target.

4. Epiphysial plate - long bones of childhood usually lengthen entirely by growth at epiphysial plates

5. Appositional growth

6. Cranium - Carnial bone enclose and protect brain it also provides attachment site for head neck and muscle.
