Question

Compare, contrast, outline the steps of intramembranous ossification and endochondral ossification and name one bone that goes through each process.

Answer 1

Endochondral ossification and intramembranous ossification are the two methods of bone formation, in both process osteoblast is involved.

Intramembraneous ossification and endochondrial ossification are involved inthe formation of bone tissue

In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue.The process begins when mesenchymal cells in the embryonic skeleton gather together and begin to differentiate into specialized cells

In endochondral ossification, bone develops by replacing hyaline cartilage, Cartilage does not become bone. Instead, cartilage serves as a template to be completely replaced by new bone

Intramembraneous ossification forms the flat bones of the skull, face, jaw, and center of clavicle. bone is formed in sheet-like layers that reseamble a membrane.
Endochondrial ossification forms most bones in the body, mostly long bones, and replace cartilage with bone.Bones at the base of the skull are formed by this process

Intramembraneous ossification does not form an intermediate cartilage.

Endochondrial ossification proceeds through intermediate cartilage

Intramembraneous ossification stops at the age of 18 years in females and at the age 21 years in males

Endochondrial ossification stops at the age of 2 years

Endochondral ossification takes much longer than intramembranous ossification
