They develope in the fetus from masses of hyline cartalige shaped like future bony structures.
it develops in the diaphysis in long bones
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.

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.
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.
Long bones are developed by endochondral ossification, which requires a cartilage precursor.
Chondroblasts are responsible for the early stages of endochondral ossification. These cells secrete cartilage matrix to form the cartilaginous model that will later be replaced by bone.
They wouldn't grow or get bigger.
