QuestionAnswer
Epinephrine (adrenaline) Norepinephrine (noradrenaline/Levophed) Adrenal medulla Increases heart rate increases force of cardiac muscle contractions increases breathing rates increases blood pressure decreases digestive activity
Aldosterone Adrenal cortex causes water retention maintains blood volume and blood pressure
Cortisol Adrenal cortex increases blood glucose levels affects protein and fat metabolism
Androgens Adrenal Cortex Stimulate the early development of reproductive organs Supplement primary sex hormones from the gonads
Growth Hormone (GH) Anterior Pituitary (blood) Increases size and division of cells
Prolactin (PRL) Anterior Pituitary (blood) Sustains milk production afterbirth
Thyroid Stimulating Hormone (TSH) Anterior Pituitary Controls secretion of thyroxin from thyroid gland
Adrenocorticotropic Hormone (ACTH) Anterior Pituitary Controls cortical secretion from the adrenal gland Negative feedback loop Circadian (24hr) pattern
Follicle Stimulating Hormone (FSH) Anterior Pituitary Females: development of follicles in ovaries Males: development of sperm
Luteinizing Hormone (LH) Anterior Pituitary Females: Controls hormones that promote release of eggs
Antidiuretic Hormone (ADH) Posterior Pituitary Causes kidneys to conserve water Increases blood pressure
Oxytocin Posterior Pituitary Contracts muscles in the uterine wall
Insulin Pancreas Decrease blood sugar levels
Glucogon Pancreas Raises Blood sugar levels
Parathyroid Hormone (PTH) Parathyroid Gland Increases blood CALCIUM levels Decreases blood PHOSPHATE levels Affects bones, kidneys, intestines
Thyroxine (T4) Thyroid Increases energy release from cells Increases growth rate Stimulates nervous system
Triiodothyoronine (T3) Thyroid Same as T4 but 5x stronger!!! Increases energy release from cells Increases growth rate Stimulates nervous system
Calcitonin Thyroid Lowers blood Calcium and Phosphate
PRIMARY DYSFUNCTION Disorder with the ENDOCRINE GLAND
SECONDARY DYSFUNCTION Disorder with the PITUITARY
TERTIARY DYSFUNCTION Disorder of the HYPOTHALYMUS
SIADH Posterior Pituitary Dysfunction Hypersecretion of ADH ADH is released despite normal or low plasma osmolarity. Inappropriate free water retention results in hypoosmolar state with dilutional hyponatremia
Diabetes Insipidus Hyposecretion of ADH or lack of response of kidney to ADH Too little ADH results in loss of free water, dehydration. Decreased water reabsorption in renal tubules. Decreased intravascular fluid volume leads to increases serum osmolality (hypernatre
