normal growing up.the person has stopped growing and the bone is being laid down in the growing parts of the bone,so no more growing
Yes, epiphyseal plates are cartilaginous joints located near the ends of long bones in children that are involved in the process of bone growth and ossification.
Long bone growth in length occurs at the growth plate, also known as the epiphyseal plate. This is a cartilaginous area at the ends of long bones where new bone tissue is formed, leading to longitudinal bone growth.
The femur is formed through the endochondral ossification process. This is where bone replaces the cartilage. There are six steps in this type of ossification and they are as follows; one the development of cartilage model, two the growth of the cartilage model, three the development of the primary ossification center, four the development of the medullary cavity, five the development of the secondary ossification centers, and six the formation of articular cartilage and the epiphyseal plate.
No the overproduction of growth hormones can cause pituitary gigantism. The over production of Sex hormones( estrogen /testosterone) can cause premature ossification;estrogen more so than testosterone.
The region you are referring to is called the ossification or metaphysis zone of the epiphyseal plate. In this area, new bone tissue is formed as osteoblasts replace the hyaline cartilage. This process helps in the longitudinal growth of bones during childhood and adolescence.
After ossification, cartilage remains in the articular cartilage at the ends of long bones. This cartilage provides a smooth surface for joint movement and helps reduce friction and absorb shock. Additionally, small amounts of cartilage can also be found in the growth plates, or epiphyseal plates, which are responsible for bone growth during childhood and adolescence.
The epiphyseal plate is a section of hyaline cartilage that seperates the epiphysis from the diaphysis in long bones. The growth and ossification of the epiphyseal plate is responsible for the bone growing longer. Articulate cartilage is similar, however, it is found on the outside layer of the epiphysis. It grows and resorbs allowing for the remodelling of the bone. The epiphyseal line is the remains of the epiphyseal plate once it has stopped growing.
Bones grow in length by endochondral ossification. It begins with cartilage that acts like a model of the bone that will grow. The bone grows in length and diameter(appositional). the structure that allows this is the epiphyseal cartilage that seperates the epiphysis from the diaphysis. When the bone is fully grown this cartilage will become bone and simply the epiphyseal line.
The chondrocytes of the epiphyseal cartilage enlarge and divide, which increases the thickness of the cartilage. On the shaft side, the chondrocytes become ossified, and "chase" the expanding epiphyseal cartilage away from the shaft.
The flexible connective tissue found in the immature skeleton epiphyseal plate and on joint surfaces is called hyaline cartilage. It provides cushioning and support for the bones during movement and growth. Over time, hyaline cartilage can be replaced by bone tissue in a process known as ossification.
The region of longitudinal growth in a child is the epiphyseal plate, commonly known as the growth plate. This area is located at the ends of long bones and is responsible for bone lengthening during childhood and adolescence by the process of endochondral ossification. Once growth is complete, the growth plate closes and becomes a bony structure known as the epiphyseal line.
The sequence of processes during bone elongation at the epiphyseal plate includes: proliferation of chondrocytes, hypertrophy of chondrocytes, calcification of the cartilage matrix, death of chondrocytes, invasion of blood vessels and osteogenic cells, and finally ossification of the cartilage leading to bone formation.
