Hormones Flashcards
Adrenal medulla releases what in response to sympathetic nervous system
Epinephrine and norepinephrine
Regulates sodium and potassium levels and produces androgen hormones
Adrenal cortex
What two hormones regulate blood glucose levels?
Glucagon and insulin
The kidneys release erythropoietin (EPO) which stimulates what?
Red blood cell production in the bone marrow
Regulation of calcium ion levels in body fluids
Parathyroid Hormone (PTH)
Steroid hormones is cholesterol released by
Reproductive organs
Adrenal glands
Kidneys
Inside the cell in the nucleus (lipids)
Secretes releasing hormones to control anterior pituitary responsible for hormones and posterior pituitary
Hypothalamus
Different zones of the adrenal cortex are
Zona glomerulosa
Zona fasciculata
Zona reticularis
Oxytocin
Released in response to sensory input
Stimulates contractions during labor, ejection of milk
Increase in solute concentration of blood or decrease in blood pressure and volume is
Antidiuretic Hormone (ADH)
Alpha cells release
Glucagon
Beta cells produce
Insulin
Diabetes mellitus type 1, type 2
Type 1- insulin protection from pancreatic beta cells
Type 2-most common form of diabetes mellitus
When pancreas isn’t making insulin it is called
Diabetes mellitus
Calcitonin
Promote absorption of calcium salts for bone deposition
Antagonistic Hormone difference between 1 and 2
1- renin
2- Secretes aldosterone
(Holds on to salt meaning volume)
Supports protein synthesis, cellular growth, assist energy metabolism and storage
Growth Hormone
Secreted by the pineal gland
Melatonin
Melenon
Lateral site stimulating Hormone
GAS
general adaptation syndrome
In larn and in phases
Hyper-secretion of GH before bone fusion
Gigantism
Hypersecretion of GH after bone fusion is
Acromegaly
Difference between adrenal cortex and medulla
Cortex- outer
Medulla- inner
Hormones inside the adrenal cortex are
Mineralocorticoid
Glucocorticoids
Androgens
Capillary system connect by short veins, carry’s neuro s secretions to anterior lobe to pituitary, antidiretic Hormone in oxytocin from posterior pituitary
Hypophyseal portal system
Difference first and second messenger
First message- relaying message to intracelluar intermediary
Second message- affects enzyme activity and chances cellular metabolic reactions
Hypersecretion Of
Hormones
Hypo secreation
Or overproduction
Allows passage of glucose and amino acids across plasma membrane into growing cells
Insulin
Renin activities
(RAAS) renin-angiotensin-aldosterone system
Hyperglycemia
Abnormally high blood glucose levels
Glycosuria
Glucose in urine
Excessive urine production
Polyuria
Regulate activities of gonads
Gonadotropins
FSH
Follicle stimulating Hormone
