MICROANATOMY

Detailed explanation-1: -Growth hormone levels are increased by sleep, stress, exercise and low glucose levels in the blood. They also increase around the time of puberty. Growth hormone release is lowered in pregnancy and if the brain senses high levels of growth hormone or insulin-like growth factors already in the blood.

Detailed explanation-2: -Pubertal growth results from increased sex steroid and growth hormone (GH) secretion. Estrogens appear to play an important role in the regulation of pubertal growth in both girls and boys.

Detailed explanation-3: -Children with precocious puberty experience early growth spurts because of the abnormally early rise in sex hormone levels in their bodies. Initially this causes these children to grow taller than other kids their age, but their skeletons mature more rapidly.

Detailed explanation-4: -Kids actually tend to grow a bit faster in the spring than during other times of the year! A major growth spurt happens at the time of puberty, usually between 8 to 13 years of age in girls and 10 to 15 years in boys. Puberty lasts about 2 to 5 years.
