Explanation:
Detailed explanation-1: -In the last stage of prenatal bone development, the centers of the epiphyses begin to calcify. Secondary ossification centers form in the epiphyses as blood vessels and osteoblasts enter these areas and convert hyaline cartilage into spongy bone.
Detailed explanation-2: -Secondary bone is further classified as two types: trabecular bone (also called cancellous or spongy bone) and compact bone (also called dense or cortical bone).
Detailed explanation-3: -Spongy bone can be converted to compact bone by the action of osteoblasts, bone cells that secrete the material that creates the compact bone matrix. It is through this process that the long bones in a human embryo develop.
