Hormone Secretion Regulation:
Normally the secretion of hormones is regulated so there is no overproduction of hormones. Various conditions result if this does not occur.
Types of Negative Feedback Systems:
1. levels of chemicals in the blood
2. nerve impulses
3. Chemical secretions from the hypothalamus
Nerve Impulses
stimulate endocrine glands such as the adrenals to release epinephrine/norepinephrine
Releasing hormones
stimulates the release of hormones from the blood
Inhibiting hormones
prevents the release of hormones from the blood
Pituitary Gland
called the "master gland," is a small round structure attached to the hypothalamus, consists of anterior and posterior.
4 of the 7 hormones secreted by Pituitary gland
Human Growth Hormone, Thyroid Stimulating hormone, Follicle stimulating hormone, melanocyte stiumlating hormone
Posterior Pituitary
stores and releases hormones made elsewhere including Oxytocin and Antidiuretic hormone
oxytocin
involved in birth process
Thyoid Gland
located just below larynx and in front of the trachea. Produces calcitonin
Parathyroid Gland
posterior of throid gland
Parathyroid Hormone
controls the level of ca++ and phosphate levels in a different way than calcitonin
Adrenal Glands
two glands located superior to each kidney. outer part= adrenal cortex. inner part= adrenal medulla. produces important hormones
Mineral Corticoids
control the homeostasis of water, sodium, and potassium
Aldosterone
helps regulate blood pH, blood volume, and blood pressue
Glucocorticoids
concerned with metabolism and resistance to stress. increase the availability of PTH
Gonadocorticoids
adrenal sex hormone including estrogen and androgens
Eprinephrine and Norepinephrine
aka adrenaline and noradrenaline. primary hormones of flight-or-fight
Pancreas
both endocrine and exocrine, located slightly below the stomach, and contains cell clusters called Islets of Langerhans
Alpha cells
secrete glucagon hormone
Beta Cells
secrete inculin hormones
Glucagon
increases your body glucose level to make blood sugar levels rise
Insulin
decreases blood sugar levels when too high by speeding up conversion of glucose into glycogen
Type I diabetes
more common under 21, pancrease is destroyed by antibodies and can't make insulin, will always be dependent on insulin, high sugar levels
Type II diabetes
multifactorial, fewer receptors to br ing insulin/glucose across cell membrane which wears out pancreas. Insulin is not made correctly
Ovaries
female gonads, produce estrogen and progesterone
Teste
produce testosteron, controls many behaviors and characteristics
Pineal Gland
makes melatonin in responses to light/dark cycle exposure
Thymus gland
Found located behind sternum and between lungs. Makes some cells produce antibodies and helps T-cells mature
stressor
any disturbance which stimulates the hypothalamus to initiate changes to respond to it
