hormones are the organic compound of varying structural complexity .these substance directly pour into the blood with out effecting the receiving cell .their function is to control enzymes or reinforce another chemical substance . basically hormone are different types according to the composition

1) proteins glucagon & insulin

2) amino acid adrenaline & non adrenaline (epinephrine & norepinephrine )

3)peptides & poly peptides vasopressin , oxytycin ,antideurtic hormones

4) steroids cortisole , testosterone and ostrogen

hypothalmus
it is the part of forebrain , it produces primary hormones . it is here many sensory stimuli is converted into harmones. it is believed oxytacin ,vasopressin and anti deurtic hormones produced in this part and stored . laterly , released upon the stimulus .
pituitary gland it is called master gland its produces primary hormones along with the trophin hormones , this gland has three parts anterior , median and posterior .

anterior part secretes the folowing hormones

somatotrophin hormones

somatotrophin releasing factor (SRF) is secreted trough out the life it primary function is growth , after maturity , this particular hormones involve in protein synthesis ,

deficiency
if it is secreted in less , under production this condition is dwarfism

over production
if it is over produced then abnormal development of hands , feet and jaw takes place it is dwarfism

thyroid stimulating hormone (tsh)
release of the tyrotrophin releasing factor (SRF) stimulate the production of thyropin in the blood . if it is under condition tsh increses in production . it hormone release during the time of growth and maturation .
it acts directly on the cell of thryod galand , increases its number and activity

adrenocorticio stimulating hormonres
release of he cortico releasing factor boost the product of cortico steroid hormones . these hormones increases the steroid , in he situation of fear , pain and emergency its production increases and rises .

gonandotrophin hormones gh

these are follicle stimulatng hormone , luitenizing hormones , interstitial cell stimulating hormones ,
these hormones give secondary sexual character and in women brings pregnancy , the follicle stimulating hormones helps in release of egg from ovum . in male testosterone activates the epithelium layer of the germinal .cell , in female prolactin hormones brings milk production , buckling , lh and fsh acts to bring leutinzation , yellowing of the corpus leutum .

median lobe following hormones secretes by median lobe
melanophore stimulating hormones . it stimultes melanocytes in the pregnancy , its bring dark brown pigments in the face of women after it pregnancy ,
