Bone Growth

The process of bone growth at the epiphyseal plate

How Does Bone Growth at the Bone marrow Work?

During the period when a person is growing up, the epiphyseal plate – which is a structure at the back of the thigh, right below the tail – contains lots of bones. Whenever a body part has to grow, it grows through the help of the epiphyseal plate. This process of bone growth at the epiphyseal plate is known as intramembranousization. When the growing process takes place at the level of the bone – as it does during the development of the breast, finger, and toenails – the process of bone growth at the epiphyseal plate goes through two distinct processes. the method of bone growth at the epiphyseal plate is understood as intramural growth and therefore the process of bone growth at the dermal layer is named dermal matrix expansion.

The reason why the skin and tissues grow faster

 

The reason why the skin and other tissues grow faster than the bones during the period of early development is that the connective tissue of the body forms a protective layer over the bones. There are various reasons for the quick growth of the connective tissues. one among them is that the bone marrow provides the essential materials that are necessary for the assembly of the connective tissues which also help within the production of the hormones that are liable for the fast development of the cells.

Growth plates are present at the base of the hairs and at the base of the teeth in humans. The epiphyseal plate is present at the back of the thigh. In the period of rapid growth at the age of puberty, the growth plate becomes very big in size and extends across the whole of the thigh. In such a situation, the muscles and ligaments in the thigh begin to expand and stretch in response to the growing pressure created by the new size of the bone marrow. This can happen when young adolescents begin to exercise vigorously. It is believed that the process of bone growth at the epiphyseal plate is similar to the process of skeletal accretion in response to the growth in weight experienced by the children after puberty.

 

In the period of rapid growth

In the period of rapid growth at the age of puberty, the bone marrow produces a large amount of HGH and other hormones responsible for the stimulation of growth plates. These hormones are secreted from the pituitary gland under the influence of the thyroid and are then transported to the bone marrow. The growth plates are stimulated and expand rapidly and in due course of time to reach the epithelium, the outer covering of the bone that undergoes a metamorphosis.

epithelium hardens it forms a solid structure

As the epithelium hardens it forms a solid structure known as osteoid tissue. Osteoid tissue is a fissured mass of the bone termed as cranium, which is made up of a cancellous matrix. the expansion of the adult bones is facilitated by the method of bone growth at the epiphyseal plate. During the early growth period of children, the process of bone accretion takes place at the osteoid tissue. As the children get older, the process of bone accretion is inhibited by the effects of the HGH produced in the body. This inhibits the growth of the bone till the stage of adolescence.

The process of bone growth at the epiphyseal plate

It is interesting to note that the process of bone growth at the epiphyseal plate is a dynamic process. It is not a simple process like the process of accretion of bones during childhood or the process of accretion of bones during adulthood. Adults usually have skeletal growth spurts between two and five years after puberty. During this period, the growth plates at the osteoid tissue experience rapid growth and rupture. In the process of this growth and rupture, the fibrin is secreted inside the osteoid tissue which forms the cartilage that serves the purpose of bone in the grown adult human body.

 

the Bone Growth

 

The adult human body continues throughout its lifetime

The growth of the adult human body continues throughout its lifetime. The main mechanism for the growth of the body is the stimulation of the human growth hormone. Human growth hormone is secreted in the human pituitary gland and stimulates the growth of the cells throughout the human body. There are various pituitary glands in the body and each secretes different types of HGH. While some secrete a specific type of HGH, the others stimulate the production of the various other hormones and consequently initiate the process of bone growth at the bone marrow.

Many different factors

There are many different factors that affect the process of bone growth in the bone marrow. They include age, gender, ethnicity, and nutrition. For the healthy and normal growth of bones, it is important to keep yourself fit and active. Apart from exercise and physical activity, there are certainly other things you can do to keep your bones strong and healthy. It is important to have a well-balanced diet and eat a balanced amount of food on a daily basis.
