- The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres. Bone formation proceeds outward from these centres. This replacement of cartilage by bone is known as endochondral ossification.

All bone formation is a replacement process. During development, tissues are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue.

Is ossification a replacement process?
What is bone ossification?
When does ossification occur?
Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation. [1]
Ossification occurs toward both ends of the bone from the primary ossification center, and it eventually forms the shaft of the bone in the case of long bones. Secondary ossification centers form after birth. Ossification from secondary centers eventually forms the ends of the bones.
Apr 9, 2024 · Bone ossification is the formation of new bone, which can occur in two ways: intramembranous ossification and endochondral ossification. This article will discuss both forms as well as clinically relevant examples.
Oct 30, 2023 · Bone formation in a developing embryo begins in mesenchyme and occurs through one of two processes: either endochondral or intramembranous osteogenesis (ossification). Intramembranous ossification is characterized by the formation of bone tissue directly from mesenchyme.

May 13, 2022 · All bone formation is a replacement process. Embryos develop a cartilaginous skeleton and various membranes. During development, these are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue.
By the sixth or seventh week of embryonic life, the actual process of bone development, ossification (osteogenesis), begins. There are two osteogenic pathways—intramembranous ossification and endochondral ossification—but bone is the same regardless of the pathway that produces it.
