GENERAL HISTOLOGY

Detailed explanation-1: -Natural levels of growth hormone fluctuate during the day, seemingly influenced by physical activity. For example, levels rise when we exercise. Growth hormone levels increase during childhood and peak during puberty. In this phase of development, growth hormone promotes the growth of bone and cartilage.

Detailed explanation-2: -Auxin promotes cell division and meristem maintenance and also plays an important role in the establishment of cellular patterning.

Detailed explanation-3: -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-4: -Growth hormone (GH) promotes stem cell activation, cell proliferation, differentiation and survival, either directly or through the induction of IGF-1. GH acts via its cell membrane receptor to initiate a range of signalling pathways, with JAK2 kinase activation of STAT5 being the most important.

Detailed explanation-5: -Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development.
