53 bone growth Biology Diagrams Growth and Development of Bones. Early in the development of a human fetus, the skeleton is made entirely of cartilage. The relatively soft cartilage gradually turns into hard bone through ossification. This is a process in which mineral deposits replace cartilage.

In the early stages of embryonic development, the embryo's skeleton consists of fibrous membranes and hyaline cartilage. By the sixth or seventh week of embryonic life, the actual process of bone development, ossification (osteogenesis), begins. There are two osteogenic pathways—intramembranous ossification and endochondral ossification—but in the end, mature bone is the same regardless

Boundless Anatomy and Physiology Biology Diagrams

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

Bone cells produce fibroblast growth factor 23 (FGF23) and osteocalcin. FGF23 regulates phosphate handling in the kidney and osteocalcin regulates energy and glucose metabolism (see below) (1,2). In this chapter the anatomy and cell biology of bone is described as well as the mechanisms of bone remodeling, development, and growth.

In the early stages of embryonic development, the embryo's skeleton consists of fibrous membranes and hyaline cartilage. By the sixth or seventh week of embryonic life, the actual process of bone development, ossification (osteogenesis), begins. There are two osteogenic pathways—intramembranous ossification and endochondral ossification—but bone is the same regardless of the pathway that Bone Development & Growth. The terms osteogenesis and ossification are often used synonymously to indicate the process of bone formation. Parts of the skeleton form during the first few weeks after conception.By the end of the eighth week after conception, the skeletal pattern is formed in cartilage and connective tissue membranes and ossification begins.
