NEET PG DENTAL EXAM

Detailed explanation-1: -This process involves the replacement of hyaline cartilage with bone. It begins when mesoderm-derived mesenchymal cells differentiate into chondrocytes. Chondrocytes proliferate rapidly and secrete an extracellular matrix to form the cartilage model for bone.

Detailed explanation-2: -Endochondral ossification is the process of bone development from hyaline cartilage. Long bones lengthen as chondrocytes divide and secrete hyaline cartilage. Osteoblasts replace cartilage with bone. Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones.

Detailed explanation-3: -Enchondral Ossification 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. Lengthening of the bone occurs in the epiphyseal growth plate.
