ENDOCRINE
Diseases associated with endocrine system
Homeostatic mechanisms of hormone regulation
Negative feedback systems
control hormone release
when hormone level rises, hormone exerts its affects further secretion is inhibited by negative feedback and hormone secretion decreses
Control Hormone secretions
Negative feedback controls release of hormones from hypothalamus controls secretions
Steroid vs Non-steroid hormone
steroid
derived from cholesterol
lipid soluble(pass through cell membrane)
non-steroid
no cholesterol mainly amino acids
hormone called first messenger
Major Endocrine Glands and Organs
Glands
Adreneal gland
Testis
Pituitary gland
Anterior pituitary
releases inhibits hormones, control secretion for anterior. Growth hormones
posterior pituitary
stores hormones, releases hormones in blood (order by hypothalamus)
Target Organs
Adrenal cortex, testis and ovaries
Ovaries
Pancreas
Thymus
Thyroid gland
Hypothalamus
Heart
Thymus
(organs)
Stomach
2 types exocrine and endocrine
Major functions of endocrine system
Maintain Homeostasis
secreting hormones and sending them into the bloodstream
hormone is sent through bloodstream to get to a target cell to send message/ make difference
negative and positive feeback
