MICROANATOMY

Detailed explanation-1: -The pituitary gland is a structure in our brain that produces different types of specialised hormones, including growth hormone (also referred to as human growth hormone or HGH). The roles of growth hormone include influencing our height, and helping build our bones and muscles.

Detailed explanation-2: -Testosterone, growth hormone (GH), and insulin-like growth factor (IGF-1) increase strength and stimulate muscle growth. Other hormones, such as cortisol, epinephrine, norepinephrine, and glucagon, increase the availability of glucose, your body’s primary source of fuel.

Detailed explanation-3: -Both GH and IGF-I play significant roles in the regulation of growth and bone metabolism and hence are regulators of bone mass. Bone mass increases steadily through childhood, peaking in the mid 20s.
