Bone formation?

Question

In bone formation, a dificiency of growth hormone will cause:

Answer 1

Growth hormone deficiency, as the name implies, is the absence or deficiency of growth hormone produced by the pituitary gland to stimulate the body to grow. Growth hormone deficiency may occur during infancy or later in childhood. Without treatment, most children with growth hormone deficiency will not reach a height of 5 feet.

Growth hormones are produced by the pituitary gland, which is attached to the hypothalamus (a part of the brain that affects the pituitary gland) located at the base of the brain. Sometimes referred to as the master gland of the endocrine system, the pituitary gland controls the functions of the other endocrine glands through the secretion of certain hormones, and also produces human growth hormone. When the pituitary gland or the hypothalamus are malformed or damaged, growth hormone deficiency may result. Damage to the pituitary gland or hypothalamus may occur as a result of abnormal formation of these organs before a child is born (congenital, or present at birth), or as a result of damage that occurred during or after birth (acquired).

Researchers have found that growth hormone deficiency may also be part of a genetic syndrome. However, in some cases, the cause of growth hormone deficiency is unknown (idiopathic).

Symptoms:

The primary symptom of growth hormone deficiency is a noticeable slow growth (less than two inches per year), although the body has normal proportions. The child with growth hormone deficiency may also have:

an immature face, meaning he/she looks much younger than his/her peers

a chubby body build

It is important to note that growth hormone deficiency does not affect the child's intelligence, and each child experiences symptoms differently. The symptoms of growth hormone deficiency may resemble other problems or medical conditions. Always consult your child's physician for a diagnosis.

Answer 2

In the deficiency of Growth Hormone, the osteocytes are NOT formed from the osteoblasts, and further bone formation stops.

hence, during childhood, deficiency of Growth Hormone causes:   dwarfism.
