| Question | Answer |
|---|---|
| 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 |
