Grave's Disease |
autoimmune disease causes hypersecretion of thyroid hormones |
|
estrogen and testosterone |
major sex hormones |
|
Antidiuretic Hormone (ADH) |
secreted in response to underhydration |
|
Parathyroid Hormone (PTH) |
hormone released by parathyroid to increase Ca+ absorption; goes to kidneys; increases osteoclasts and inhibits osteoblasts |
|
Pituitary Gland |
Gland in sella turcica |
|
Type I Diabetes |
Diabetes type caused by lack of insulin production |
|
Thyroid Stimulating Hormone |
Causes release of thyroid hormones T3 and T4 |
|
Thyroid Gland |
Butterfly-shaped gland |
|
Adipocytes |
Secretes leptin that controls appetite |
|
Insulin |
Hormone causes fat to be stored |
|
Anterior Lobe |
Portion of pituitary gland that released melanocyte stimulating hormone |
|
Posterior Pituitary |
Aka neurohypothesis |
|
Cortisol (long term), Epinephrine (short term) |
Released in response to stress |
|
Pituitary Gland |
Disorder in this gland leads to diabetes insipidus |
|
Alpha Cells |
Glucagon is produced by these cells |
|
Beta Cells |
Insulin is produced by these cells |
|
Growth Hormone (GH) |
Gigantism is caused by an oversecretion of |
|
Glucagon |
Hormone that increases blood sugar |
|
ANH/ANP atrial natriuretic hormone |
Hormone released by the heart (lowers BP) |
|
Erythropoietin (EPO) |
Hormone signals to bone marrow to produce more red blood cells |
|
Hypothyroidism |
Decreased metabolism and weight gain |
|
Pancreatic Islets |
Where alpha and beta cells are found |
|
Epinephrine |
Hormone often released at the same time as glucagon (angry!) |
|
Direct Communication |
cell to cell |
|
Paracrine Communication |
Within one tissue. ie pancreas |
|
Autocrine Communication |
Cell talking to itself. ie smooth cells of digestive system |
|
Endocrine Communication |
sends hormones across the body |
|
Glucagon and Insulin |
controls energy balance |
|
Amino acid, peptide, and lipid derivitives |
Classes of hormones |
|
Amino Acid Derivitives |
tyrosine derivitives; building block for protein; ex. adrenaline |
|
Peptide Hormones |
Chain of amino acids, form proteins. ex. oxytocin for smooth muscle contraction |
|
Lipid Derivitives |
Steroid hormones (cholesterol and reproduction estrogen/testosterone) or Eicosanoids (fat/oil) |
|
Protein synthesis, membrane permeability, genetic activity |
hormones alter |
|
Humoral Stimulus |
body measures fluid to determine if hormones need to release (pancreas) |
|
Hormonal Stimulus |
cascade effect, 1 hormone triggers multiple (TSH) |
|
Neural Stimulus |
neurons signal glands (adrenaline) |
|
ADH and Oxytocin |
posterior pituitary hormones |
|
Oxytocin |
Causes smooth muscle contraction, positive feedback loop during delivery, nourishment of infants through milk ejection, adrenaline inhibits oxytocin |
|
Thyroid Stimulating Hormone (TSH) |
causes thyroid gland to release hormones; increases metabolism; cascade |
|
Adrenocorticotropic Hormone (ACTH) |
Increase in secretion leads to release of cortisol by the cortex |
|
Addison's Disease |
Adrenal cortex unresponsive and doesn't produce enough cortisol; leads to an increase in ACTH |
|
Cushing's Disease |
Tumor in anterior pituitary; increase in ACTH and cortisol; abdomen is large as a result |
|
Follicle Stimulating Hormone (FSH) |
reproductive, impacts follicles in males and females, where ovocytes and causes cells to mature |
|
Luteinizing Hormone (LH) |
causes ovulation, triggers egg to be released; triggers release of cells to increase testosterone |
|
Prolactin (PRL) |
produces milk |
|
Growth Hormone (GH) |
increases membrane permeability, widespread growth of cells in the body; can resuly in gigantism and acromaglia; can be a carcinogen |
|
Melanocyte Stimulting Hormone (MSH) |
skin tone (minor), causes linea nigra in pregnant women |
|
Calcitonin |
increases bone growth, delivers calcium to bones, inhibits osteoclasts; produced by thyroid gland |
|
Thyroid Gland |
produces T3, T4, and calcitonin |
|
Parathyroid Gland |
parathyroid hormone (PTH), increases osteoclast activity and inhibits osteoblasts |
|
Alpha and Beta Cells |
Alpha releases glucagon, Beta releases insulin |
|
Type I Diabetes |
Beta cells can't fx, high blood sugar is corrosive to tissues as it cuts vessels |
|
Type II Diabetes |
B cells are fine but all cells become desensitized to insulin; cells can't "hear" insulin; not genetic |
|
Epinephrine (fight or flight); Norepinephrine (neurotransmitter) |
Medulla Hormones |
|
Aldosterone- decreases Na loss, goes to kidneys. Cortisol- stress hormone, released over longer periods of time under chronic stress. |
Cortex Hormones |
|
Pineal Gland |
attached to epithalamus; secretes melatonin (sleepy hormone) |
|
Complete Androgen Insensitivity Syndrome |
No testosterone receptors, high testosterone levels |
|
