They develope in the fetus from masses of hyline cartalige shaped like future bony structures.

Endochondral ossification
A humerus bone is a long bone that is formed through a process called endochondral ossification. This process involves the transformation of a cartilaginous model into bone tissue through the deposition of minerals and the formation of bone cells. The humerus bone develops in the upper arm region of the body during embryonic and fetal development.
Intramembranous ossification [flat bones] & endochondral ossification [long bones].The essential between them is the presence or absence of cartilaginous phase.Intramembranous ossification occurs when mesenchymal precursor cells proliferate & subsequently differentiate directly into osteoblasts w/c mineralize an immature bone tissue called woven bone,characterize by irregular bundles of randomly oriented collagen fibers & an abundance of partially calcified immature new bone called asteoid.At later stages this woven bone is progressively remodeled to mature,lamellar bone. Endochondral ossification entails the conversion of a cartilaginous template into bone.Mesenchymal cells condense & differentiate into chondrocytes w/c secrete the cartilaginous matrix.This embryonic cartilage is avascular,& during its early development,a ring of woven bone is formed by intramembranous ossification in the future mid shaft area.This calcified woven bone is then invaded by vascular tissue,& osteoclasts & osteoblasts are recruited to replace the cartilage scaffold w/ bone matrix & excavate the hematopoietic bone marrow cavity.
During endochondral ossification, the hyaline cartilage model in the embryo is gradually replaced by bone tissue. Osteoblasts deposit bone matrix around the cartilage model, which is then mineralized and eventually becomes mature bone tissue.

Endochondral ossification
Endochondral bone
Bone growth occurs through two primary processes: endochondral ossification and intramembranous ossification. Endochondral ossification involves the replacement of cartilage with bone tissue, primarily during the development of long bones. Intramembranous ossification, on the other hand, occurs in flat bones, where bone develops directly from mesenchymal tissue. Bone growth is also influenced by factors such as age, hormonal regulation, mechanical stress, and nutritional status, contributing to the dynamic nature of bone remodeling and maintenance.

Intramembranous ossification involves the direct formation of bone from mesenchymal tissue, primarily occurring in flat bones like the skull and clavicles. In contrast, endochondral (or intracartilaginous) ossification involves the replacement of a cartilage model with bone, which is typical in the development of long bones. The key difference lies in the initial tissue from which bone develops: intramembranous ossification starts from fibrous membrane, while endochondral ossification begins with cartilage.

No, you have it backwards. "Chondro" is the prefix for cartilage while "osteo" is the prefix for bone. Endochondral ossificiation is when the cartilage is replaced by bone, so you would have osteocytes moving into the matrix and replacing the chondrocytes.
The process of cartilage turning into bone is called endochondral ossification. This process is crucial during the development of long bones in the fetus and continues into adolescence as the growth plates close. In endochondral ossification, cartilage serves as a template that is gradually replaced by bone tissue.
The term that refers to the process of embryonic cartilage being replaced by bone cells is "endochondral ossification." This process is crucial for the development of long bones and involves the transformation of hyaline cartilage into bone tissue as the embryo develops. It plays a significant role in the growth and shaping of the skeletal system.
Endochondral ossification is the type of ossification in bones that are formed in cartilage. This process involves the replacement of cartilage by bone during development and growth.
