Cardiovascular system. Transportation of oxygen, nutrients and hormones throughout the body and elimination of cellular metabolic waste.
The growth hormone/IGF-1 system stimulates both the bone-resorbing and bone-forming cells, but the dominant effect is on bone formation, thus resulting in an increase in bone mass. Thyroid hormones increase the energy production of all body cells, including bone cells. They increase the rates of both bone formation and resorption.

Figure 6.4.2 – Endochondral Ossification: Endochondral ossification follows five steps. (a) Mesenchymal cells differentiate into chondrocytes that produce a cartilage model of the future bony skeleton. (b) Blood vessels on the edge of the cartilage model bring osteoblasts that deposit a bony collar.

By the sixth or seventh week of embryonic life, the actual process of bone development, ossification, begins in which the fibrous membranes and hyaline cartilage are replaced by bone. By the time a fetus is born, all fibrous membranes and most of the cartilage has been replaced with bone. Some additional cartilage will be replaced throughout ...
Apr 21, 2024 · Bones are often considered static structures that only offer structural support (see Image. Parts of a Long Bone). However, bones have many functions, like other organ systems. Besides serving as a framework for soft tissue, bones permit locomotion, protect vital organs, facilitate breathing, play a role in electrolyte homeostasis, and house hematopoietic sites. Bone remodeling continues ...

Human Skeletal System. The skeletal system provides the structural framework for the human body. It consists of bones, joints, cartilage, ligaments, and tendons, all of which work together to provide support, protection, and movement. The skeletal system is closely integrated with the muscular system. The functions of the skeletal system ...

Chapter 19: Skeletal System. Figure 19.1 Bone is a living tissue. Unlike the bones of a fossil made inert by a process of mineralization, a child’s bones will continue to grow and develop while contributing to the support and function of other body systems. (credit: James Emery) Bones make good fossils. While the soft tissue of a once living ...
