9 kwi 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.
1 maj 2023 · Intramembranous Ossification. This process involves the direct conversion of mesenchyme to the bone. It begins when neural crest-derived mesenchymal cells differentiate into specialized, bone-forming cells called osteoblasts. Osteoblasts group into clusters and form an ossification center.
8 wrz 2020 · Increased understanding of bone development, as well as normal and aberrant bone repair, has important therapeutic implications for the treatment of bone disease and ageing-related...
14 lip 2023 · The primary center of ossification serves as the focal point for bone growth, and osteons, the fundamental units of compact bone, play a significant role in bone structure. Osteoblasts establish interconnections through cytoplasmic processes, which transform into the canaliculi of osteons.
Heterotopic ossification (HO) is the process by which bone forms at an abnormal location, usually in soft tissue like muscle, tendons, and ligaments. While most people cannot feel the abnormal bone, they can see it.
Ossification then starts to occur at secondary ossification centers at the ends of the bone. The medullary cavity forms and will contain red bone marrow. Areas of ossification meet at epiphyseal plates, and articular cartilage forms.
30 paź 2023 · Endochondral ossification occurs in the long bones around the 6th embryonic week. It involves the formation of hyaline cartilage precursors from aggregated mesenchymal cells , and their subsequent systematic replacement by bone to form the growing skeleton.
