WebDescribe the processes of post-fetal bone growth and bone thickening Key Takeaways Key Points The epiphyseal plate, the area of growth composed of four zones, is where cartilage is formed on the epiphyseal side while cartilage is ossified on the diaphyseal side, thereby lengthening the bone. WebMay 12, 2024 · 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. Cartilage Templates
WebFrom about age 25 to age 50, bone density tends to stay stable with equal amounts of bone formation and bone breakdown. After age 50, bone breakdown (resorption) outpaces bone formation and bone loss often accelerates, particularly at the time of menopause. WebThe development of bone from fibrous membranes is called intramembranous ossification; development from hyaline cartilage is called endochondral ossification. Bone growth …
