Endocrine System

slower, longer commuincation
cell signal by release
Gland group of cellls that secrets chemicals into surroundings
Ductless: secrete Directly inton blood stream
regulated by postive and negative feedbacl loops

Nonsteriod: Protein or AA, first messenger that binds to receptor at the target cells to memebrane and than triggers 2 nd messenger with in cell that cause activity
Steroid: lipid soluble can pass through membrane and influnce gene expression in nucleus

Master Gland
- it will secret hormones that will force other glands to secrete hormones

Hypothalams controlls hormome secretion of Pituitary Gland

-produces/ releases 6 hormones controlled by hypothalamus, growth, cortasol, TSH, FSH & LH PR2

Hormones produced by hypthalamus itself & release @ poster pituitart
- 2 Hormones released Antidiuretic, Oxytocin

Secrete T3&T4 stimulate metabolism, calcitonin CT, decrease concentration of Ca with in blood keeping it stored in bone

increase in Ca by breaking down of bone

Aldostrone: efffects blood Na levels by controling kidney fuction
glucocorticoid: cortisol --> stress, bad
sex hormone --> development of sex organs

Epinerphrine and Norepinephrine
stress response

Insulin: by bara cells
Glucagon: alpha cells

Overies: estrogen
Testes: testostron

Thymosin: Body immuse system
Stomach, intestine, heart, secrete hormones

too much growth Hormones by anterior pituitary

too littler growth hormone

too little ADH kidney cannot retain water

Cretinsim: too littler during formative years effecting metabolsim
Goiter: Iodine deficiency enlarged thyroid gland abnormal hormone release

Diabetes Mellitis: chronic high blood sugar, sugar in peee
