Question

Quizplus · Accepted Answer

The long bones of the appendages are initially formed by endochondral ossification, in which a cartilage model of the bone is gradually replaced by bone tissue. Intramembranous ossification is the formation of bone tissue directly from mesenchymal cells, and is responsible for the formation of flat bones such as the skull bones. Bone remodeling refers to the continuous turnover and renewal of bone tissue throughout life. Hemopoiesis is the production of blood cells, which occurs in the bone marrow.
