Endochondral Bone Ossification--Developing Bone showing the Epiphyseal Disk (Growth Plate), 25X 照片檔

Endochondral Bone Ossification--Developing Bone showing the Epiphyseal Disk (Growth Plate), 25X. This is the head end of a Phalange in the hand--the cartilage above will form the head of the phalanx. This image shows the: Epiphyseal Disk or Growth Plate (purple, horizontal area), Hyaline Cartilage (in different stages), calcified cartilage, osteoblasts (bone forming cells), osteocytes (bone cells in lacunae), and mesenchyme (early developmental tissue). This is considered cartilage bone as contrasted to membrane bone.
