ANATOMY

Detailed explanation-1: -Endochondral ossification is the process of bone development from hyaline cartilage. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification.

Detailed explanation-2: -Enchondral bone formation represents bones formed in a hyaline cartilage template. This is the most common method by which bones form. Examples include the femur, tibia, vertebrae, and metacarpals. The process begins in centers of ossification located in the embryonic skeleton and continues into the late teen years.

Detailed explanation-3: -Flat bones [like those of the calvarium (skull) and the scapula] and foci of woven bone are formed by intramembranous ossification. In this process, bone is laid down directly in the mesenchymal collagenous matrix rather than by transmutation of a preformed cartilage model.

Detailed explanation-4: -Flat bones are made up of a layer of spongy bone between two thin layers of compact bone. They have a flat shape, not rounded. Examples include the skull and rib bones. Flat bones have marrow, but they do not have a bone marrow cavity.

Detailed explanation-5: -Endochondral ossification involves the replacement of hyaline cartilage with bony tissue. Most of the bones of the skeleton are formed in this manner. These bones are called endochondral bones.
