are chemical messengers secreted into the blood stream and stimulate the cells of another tissue or organ. They affect only cells that have receptors for them which is how they are controlled (no master control center)
has an anterior and posterior portion
is also known as adenohypophysis
Anterior Pituitary Gland
is known as the neurohypophysis, not considered a true gland; it is a mass of neuroglia and nerve
fibers that actually arise from bodies in the hypothalamus.
Posterior Pituitary Gland
cell bodies synthesis hormones that will be transported down the infundibulum and stored in the posterior pituitary. Two hormones stored there are antidiuretics hormone and oxytocin but are produced in hypothalamus
Hypothalamic or Hypothalamus
prevents dehydration by increasing water retention. It is also known as vasopressin. This causes vassal constriction to increase the blood pressure
is a hormone released during childbirth causing smooth muscles of uterus to contract causing contractions. (positive feedback). signal will cause signal causing more hormone to be produce which will increase contractions, stimulates muscles around the mammary
glands forcing milk to flow to nipple , release in surges during sexual arousal and orgasm.
is a releasing hormone that promotes TSH & PRL
TSH or Throtropin
is a releasing hormone that promotes ACTH
CRH or Corticotrophin
is a releasing hormone that promotes FSH & LH
GNRH or Gonadotropin
is a releasing hormone that promotes prolactin
PRH or Prolactin
is a releasing hormone that promotes GH secretion
GHRH or Growth Hormone
is an inhibiting hormone that inhibits prolactin PRL
PIH or Prolactin
is a inhibiting hormone that inhibits GH & TSH secretions
is a stimulating hormone for gonadotropins (sex organs). In the female it stimulates egg development
and in the male it produces sperm production
FSH or Follicle
is a stimulating hormone for gonadotropins.
If females it stimulates ovulations and stimulates the egg to produces estrogen and progesterone. In the male it stimulates interstitial cells of the testes to secrete testosterone.
LH or Luteinizing
is a stimulating hormone. It stimulates growth of the thyroid and secretion in thyroid hormones (T3 and T4)
TSH or Thyroid
is a stimulating hormone. It stimulates the adrenal cortex to secrete hormones particularly cortisol.
ACTH or Adrenocorticotropic
is a stimulating hormone, not tropic. In
the female these rise during pregnancy, has no effect until after pregnancy and stimulate milk production. In the male it makes the testes more sensitive to the luteinizing hormone producing more testosterone.
PRL or Prolactin
promotes tissue growth of bones, muscle and cartilage, 1000 times more produced than any other hormone in the body, stimulates the liver to produce growth factor or stimulates.
GH or Growth Hormone
is going to have control hormones that are released to anterior pituitary 2 of which are inhibiting. None of the 7 released here will have a direct affect yet. It is basically a control mechanism that will cause the release of other hormones.
releases sleep hormone called melatonin (sleepy). It also secretes serotonin (happy).
patients suffer severe depression with not getting enough sunlight
SAD or Seasonal Affective Disorder
can be helped with a couple hours of sun light or photo therapy
is an important component of serotonin. This might be a great alternative over Prozac, along with omega 3 from
fish and exercise 3-4 times per week
is present in turkey causing you to get sleepy
is an amino acid that moves into the follicle
is the training ground for your t-lymphocytes and pertains to your immune system. It secretes 2 hormones;
thymopoietin and thymosin. They stimulate t-lymphocytes development and activation
weighs 2/3 of ounce and secretes T3 and T4, primary function is to increase the metabolic rate. Function will increase during colder weather to keep you warmer. It accelerates the catabolism of fats, carbs and proteins for the use of fuel. Proper functions will help with alertness and increases the increase the secretion of growth hormones, and regulates blood cholesterol levels.
would have decreased energy, decreased alertness, colder extremities, weak nails and weight gain
is secreted by thyroid. It is secreted when blood calcium levels are too high. This will cause bone deposition (driving calcium back into the bone)
will drive the thyroid into hypothyroidism. Men can suffer from estrogen dominance as well. This can be caused by synthetic exposure to estrogens, eggs, red meat, milk, and soy. It can increase the chance of breast and/or thyroid cancer
produces one hormone called the parathyroid hormone. It activates vitamin D, promotes intestinal
calcium absorption, and inhibits urinary excretion of calcium. It overall purpose is to regulate the calcium
in the blood. Opposite effect of Calcitonin
has two halves; adrenal medulla and the adrenal cortex
consists of neurons. It is referred to as the sympathetic nervous system. (fight or flight). They are called epinephrine and norepinephrine.
is also known as adrenalin. It also inhibits insulin secretion sharpening thinking ability making muscles use alternative fuel. They use gluconeogenesis. This is produced by fat and proteins. It increases blood pressure and air flow. It will accelerate the breakdown of glycogen. Dopamine is also released
has 3 layers; Zona Glomerulosa, Zona Fasciculata, and the Zona Reticularis
is the outer layer of the adrenal cortex. It produces a hormone called aldosterone. This hormone acts on the kidneys to control electrolyte balance and promotes sodium retention
