Human growth
hormone(HGH) is a substance produced by a gland in the brain
called the pituitary gland. This gland is often called the
master gland, because it controls many of the other glands
in the body. It is about the size of a pea and it lies above
the roof of the mouth, beneath the brain. human growth
hormone is a protein and is made of 191 building blocks
called amino acids. It is also called somatotropin or
somatropin which are the Greek words for body growth.
Human
growth hormone(HGH) travels through the
blood and stimulates the liver to produce a
protein called insulin-like growth factor
#1(IGF-1). IGF-1 helps the cartilage cells
located at the ends of long bones called the
growth plates to multiply, which is where bone
growth occurs. During puberty age, this leads to
growth in the length of the bones and increases
one's overall height.
