Hormones are organic molecules derived from |
Lipids or proteins |
|
Are secreted by endocrine tissues |
Hormones |
|
Affected cells which hormones take its effect |
Target cells |
|
Specific to organ and hormones |
Receptors |
|
Slows or stop secretion when the metabolic changes triggered in the target cells become evident |
Negative feedback mechanisms |
|
Tends to decrease blood glucose concentration |
Insulin |
|
Less commonly observed, results in an increased hormone secretion when the metabolic changes becomes evident or blood hormone levels increase. |
Positive feedback |
|
Trigger uterine contraction, whick pushes the baby and stretch the birth canal. |
Oxytocin |
|
Cyclic rises and falls in the secretion of several hormones related to reproduction |
Biological clock |
|
Secreted from embryonic tissue in a structure called |
Chorion |
|
Secreted during the early stages of development in the womb |
Human chorionic gonadotropin |
|
Release of a mature ovum |
Ovulation |
|
Hormones that promote the conditons necessary for successful development of the offspring |
Estrogen and progesterone |
|
Thickens and becomes more vascular |
Endometrium |
|
Stimulates ovary's secretion of progesterone and estrogen preventing the decrease of hormones |
hCG |
|
It develops and it begins to secrete its own progesterone and estrogen |
Placenta |
|
Very high hCG levels during pregnancy |
First trimester |
|
Common form of pregnancy testing |
hCG urinalysis |
|
More convenient hCG test uses |
Monoclonal antibodies |
|
Help ensure that the results are valid and not due to a side reaction or an experimental error |
Control tests |
|
Produced by the corpus luteum |
Progesterone |
|
Produced only in the ovaries |
Estrogen |
|
Certain drugs that contain hcg |
Profasi, pregnyl, novarel |
|
Anterior pituitary hormone that stimulates the secretion of sex hormones by the gonads |
Luteinizing hormones |
|
Conserves water; constricts blood vessels |
Antidiuretic hormones - posterior pituitary in kidney |
|
Increases uterine contraction, increase milk from mammary gland |
Oxytocin - posterior pituitary in uterus, mammary gland |
|
Increases gene expression, breakdown lipids, increase blood glucose levels |
Growth hormone - Anterior pituitary in most tissues |
|
Increase thyroid hormone secretions in T3 and T4 |
Thyroid-stimulating hormone - anterior pituitary in thyroid gland |
|
Increase secretion of glucocorticoid hormones such as cortisol |
Adenocorticotropic hormone |
|
Increase melanin production in melanocytes |
Melanocyte-stimulating hormones |
|
Promotes ovulation and pregosterone production |
Luteinizing hormone |
|
Promotes follicle maturation and estrogen secretion in ovary, sperm cell production. |
Follicle stimulating hormone |
|
Stimulates milk production prolongs progesterone secretions following ovulation |
Prolactin |
|
Increase Metabolic rates essential for growth |
Thyroid hormones |
|
Decrease rate of bone breakdown |
Calcitonin |
|
Increase rate of the bone breakdown by osteoclasts |
Parathyroid hormones |
|
Increases cardiac output, increase blood flow |
Epinephrine |
|
Increase rate of sodium transport |
Aldosterone |
|
Increase lipids and protein breakdown |
Cortisol |
|
Inhibits secretion of gonadotropin releasing hormone |
Melatonin |
|
Promotes immune system, development and functions |
Thymosin |
|
Increase uptake and use of glucose and amino acids |
Insulin |
|
Increase breakdown of glycogen and release of glucose |
Glucagon |
|
Aids in sperm cell production, maintenance of functional reproduction |
Testosterone |
|
Mediate inflammatory responses, increase uterine contraction and ovulations |
Prostaglandins |
|
Inhibits secretion of gonadotropin-releasing hormone |
Melatonin |
