growth hormone functions
increases the glucose levels in the blood by lipolysis of adipocytes and decreasing the insulin level. Increases the amino acid level in the blood
prolactin is also known as
mammotropic hormone, luteotrophin,
the degeneration of the anterior lobe of the pituitary causes a disease called
Simmonds disease or acromicria
functions of melatonin
the biological clock, maintains body temperature, metabolism, pigmentation, and defense mechanisms of the body. it inhibits ovarian functions and delays sexual maturity
