Similarities and differences between intramembranous and endochondral ossification

Answer 1

Similarities and differences between intramembranous and endochondral ossification
Ossification is the process of bone formation. Intramembranous and endochondral ossification are the two main processes of bone formation that occur during fetal development.
Similarities between intramembranous and endochondral ossification; they turn cartilage into bones during bone formation and they both involve bone cells such as calcium, vascular supply and osteoblasts.
Differences between intramembranous and endochondral ossification; In intramembranous ossification, an intermediate cartilage is not involved, rather the bone tissue is directly laid on a primitive connective tissue called mesenchyma while in endochondral ossification, cartilage is used as a precursor for bone formation. Also, in cases of fractures, the healing process by plaster of Paris occurs through endochondral ossification while fractures which are treated by open reduction and internal fixation are healed by intramembranous ossification.

Answer 2

Answer:

Explanation:

Ossification is the biological process of bone formation

Difference between Endochondral Ossification and Intramembranous Ossification

In Endochondral process of bone formation the cartilage is laid first over which the bone is formed/laid and it is responsible for making long bones while in the intramembrous ssification bone tissue is developed directly over the mesenchymal tissue and not on the cartilage and it is responsible for forming flat bones such as  jaws , collar bones etc.  

Similarities between Endochondral Ossification and Intramembranous Ossification

The structure and function of the bone remains same in the both the processes of bone formation.
