Hormone:is a substant as massenger secreated from gland to blood ( directly or in the duct)
_in the body present tow type from gland: 1_Endocrine(secreated product to blood directly) 2_Exocrine (secreated product in the duct)
Classification of hormone 1_according chemical *protein_poly peptid as insulin glucagon *amino acid derived as thyroid *steroid as sex hormone 2_according solubility *water soluble *fate soluble 3_according mechanism action 4_ according site action
What is the dynamic test? - endocrine secreated excessive or deficient hormone causing abnormality may be primary or secondary can be diagnosis by exogenous hormone as 1_stimulation( in the case hypo) 2_supperation(inthe case hyper)
Inthe pitutary gland tow lobes 1_anterior 2_posterior
posterior secreation hormone •ADH(vasopressine or arginine vasopressine)synthesized from in the supraoptic nuclei of the hypothalamus (ADH)acting water reabsorption from collecting duct of kidney •Oxytocine hormone synthesized in the paraventricular nuclei of hypothalamus also synthesized in the posterior neurophysine acting control ejection milk from lactating breast and uterin contraction
