Difference Between Endochondral Ossification and Intramembranous Ossification

Endochondral ossification is the method of forming a bone through a cartilage intermediate while intramembranous ossification directly forms the bone on the mesenchyme. ... The main difference between endochondral ossification and intramembranous ossification is the method of bone formation and types of bones formed.

What is the main difference between endochondral ossification and intramembranous ossification?

During development, these are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage.

What are the 2 types of ossification?

There are two types of bone ossification, intramembranous and endochondral.

What are the steps of Intramembranous ossification?

Intramembranous Ossification Intramembranous ossification follows four steps. (a) Mesenchymal cells group into clusters, and ossification centers form. (b) Secreted osteoid traps osteoblasts, which then become osteocytes. (c) Trabecular matrix and periosteum form.

What is the process of endochondral ossification?

Endochondral ossification is the process by which growing cartilage is systematically replaced by bone to form the growing skeleton. This process occurs at three main sites: the physis, the epiphysis, and the cuboidal bones of the carpus and tarsus.

What are the 6 steps of endochondral ossification?

Terms in this set (6)

• Cartilage enlarges; Chondrocytes die.
• blood vessels grow into perichondrium; cells convert to osteoblasts; shaft becomes covered with superficial bone.
• more blood supply and osteoblasts; produces spongy bone; formation spreads on shaft.
• Osteoclasts create medullary cavity; appositional growth.

What happens during Intramembranous ossification?

The direct conversion of mesenchymal tissue into bone is called intramembranous ossification. This process occurs primarily in the bones of the skull. In other cases, the mesenchymal cells differentiate into cartilage, and this cartilage is later replaced by bone.

What is an example of ossification?

Intramembranous ossification is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, the mandible, and the clavicles. Ossification begins as mesenchymal cells form a template of the future bone.

What happens during ossification?

Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as mineralized bone. The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres. Bone formation proceeds outward from these centres.

What are the steps of ossification?

The process of bone formation is called osteogenesis or ossification. After progenitor cells form osteoblastic lines, they proceed with three stages of development of cell differentiation, called proliferation, maturation of matrix, and mineralization.

What is the first step in endochondral ossification?

What is the first step of Endochondral ossification? A bone collar is formed. Osteoblasts secrete osteoid along the hyaline cartilage shaft diaphysis, encasing it into bone. This is the bone collar.

What is an ossification center?

A primary ossification center is the first area of a bone to start ossifying. It usually appears during prenatal development in the central part of each developing bone. In long bones the primary centers occur in the diaphysis/shaft and in irregular bones the primary centers occur usually in the body of the bone.
