Bone tissue formation

The video tutorial by Nicole from Kenhub explores the histology of bone formation, focusing on two types: intramembranous and endochondral ossification. Intramembranous ossification involves mesenchymal stem cells differentiating into osteoblasts, which secrete osteoid that calcifies into bone. Endochondral ossification starts with a hyaline cartilage mold that ossifies into bone, with distinct zones in the epiphyseal plate. Clinical conditions like rickets and achondroplasia are discussed, highlighting the importance of vitamin D and genetic factors in bone health.
