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 ,

hormones are the organic substance of varying structural complexity , hormones does not initiate new biochemical reaction but tey reached the target cell through blood , it has teh ability to control its influence trough enzymes or producing its impact . hormones are different substances

protein insulin and glucagon

amino acid thyroxin , vasopressin and oxytcin
polypeptides epinephrine , non epinephrine , anti deurtic hormones
steroids cortisone , adrenaline , non adrenaline

hypothalmus
it is the main part of forebarain , it possess the part where sensory stimuli are converted into the hormonal responses , it is believed anti deuratic andoxytacin are secreted from the hypothalmus , where these hormones released upon stimulus , and stored in posterior lobe

pituitary gland
pituitary gland is the main part of hypothalmus . in pituitary gland three parts or lobes are important because it releases the trophin hormones in additional to primary hormones

anterior lobe
anterior lobe secreted different hormones
somatotrophin hormones
somatotrophin releasing factor secreted through out the life , its excess secretion during period of rapid growth , this hormones after maturation synthesis protein
over secretion
if it is excessive secreted during early period ,i nlater stage abnormal development of hands , feet and jaws happens .
under secretion
if it is secreted in under quantity dwarfism produces ,with small development and growth of an individual

tryroid stimulating hormones
thyrotrophin releasing factors releases thyroxin hormones in the body . it primary function is on growth and development
if thyroxin is less then its concentration increases and vice versa
it also act on the thyroid glans its increases its number and excretory power

adrenocorticotrophin hormones
release of the corticotrophin releasing factor from the adrenaline increases te concentration of steroid in emergency , fear and flight situation , excess nad deficiency affects the normal function of adrenaline

lh , icsh and lth gondotrophin hormones
these are follicle stimulating hormones fsh , leutinizing hormones lh , leutotrophin hormones lth

follicle stimulating hormones basically stimulates teh producton of eggs from the ovum , the prolactin hormones shares the common hypothalmic stimuli , and it is inhibited by prolactin inhibiting factor. the fsh nad leutinizing hormoes acts synergentically to produce eggs nad in male it also mature the epithelium tissues if testes fsh acts with conjuction of lth and releases oxytacin to produce from ovum ,prolactin stimulaes te milk production . in male the testosterone is released by the leutotrophin hormones . basic functioni sthe male and female secondary sex characters

median lobe ' the median lobes secreted the following hormones
melanophore stimulating hormones
the hormones affects the melanocytes in teh skin cell , in the skin dark patches formed due to the excess secretion of the hormones , but this hormoes over affects during addison disease distinguish by over excretion

posterior lobe
vasopressin or antideurtaic hormones
vasopressin releases to maintain the blood osmotic pressure , water volume and eh electrolytes concentration . these hormones released upon the osmo receptors in the hypothalmus , in dry weather , this hormones conserves the water and maintain the body hydration , excess sweating to maintain homo esthasis

thyroid gland
