What is the major stimulus for the release of parathyroid hormone from the parathyroid gland


Parathyroid Hormone

Demineralizes bone and raises blood calcium levels


Depression of the CNS and lethargy

Antidiuretic Hormone

Secreted in the posterior pituitary


Secreted in the Adrenal Medula


Secreted in the thyroid gland


Stimulates sodium retnention

Thyrotropin releasing hormone is produced by which area of the diencephalon


The venous conncection between the hypothalamus and the adenohophysis is called the

Hypophyseal Portal System

The connection between the hypothalamus and the neurohypophysis is the

Hypothalmo-hypophyseal tract

LH and FSH

Gonadoptropins secreted by the adenohypophysis

The most common form of diabetes

Type 2 Diabetes Mellitus

Non hormonal material secreted through dicts onto internal and external body surfaces

Exocrine glands

The most common mechanism for hormonal activity on target cells

Hormones stimulate messenger activation or deactivation which affect other cell events

Bind to intracellular receptors within hte cell nucleus and stimulate gene activation

Steroid hormones

Bind to specific receptros on the surface of the cell and function by way of a second messenger system

Amino Acid hormones

Enzyme link between a first messenger and a second messenger in a cell activated by an amino acid hormone

Adenylate cyclase

When stimulated by FSH, follicle cells in the ovary produce large quantities of which femal hormone


During pregnancy, the corpus luteum, a structure on the ovary, secretes what hormone


Produced in heart cells, promotes sodium loss, suppresses ADH secretion, reduces blood pressure by decreasing blood volume

Atrial Natriuretic Peptide Hormone

Hormone produced in the kidneys that increases the number of red blood cells released from bone marrow


Caused by excess secretion of growth hormone prior to puberty, body features are normal but very large


Hormone secretion that would be affected by damage to the superotpic nucleus of the hypothalamus


Hormone deficiency that causes diabetes insipidus



Will lower blood calcium by excreting it in the kidneys and depositing calciumin bones.

Damage to the cells of the zona fasciculate of the adrenal cortex would result in

decreased glcogenesis and the ability to convert lipids to glucose

A rise in angiotensin 2 levels would result in

Fluid retention because of angiotensin stimulating release of aldosterone


85% epinephrine 15% norepinephrine = adrenaline

Adult GH Hypersecretion



Lipid hormones; eicosinoids

Important anablic hormone

Growth hormone

Involved in water balance causeskidney to conserve water

Anti diuretic hormone or aldosterone

Stimulates milk production


stimulates milk letdown


increases uterine contractions during bitrth


Major metabolic hormone

TH (T3 & T4)

Causes reabsorption of sodium ions by kidneys


Tropic hormone that stimulates thyroid gland to secrete thyroid hormone


Hormone secreted by neurohypophisis

ADH and oxytocin

steroid mineralcorticoid hormone


ductless gland, through which hormones are released into the blood stream and effects other glands


Renin angiotensin

Major mechanism for the regulation of aldosterone

Parathyroid Hormone

Hormone secreted by the parathyroid gland responsible for increasing plasma calcium levels

Graves disease

an autoimmune disease where the body produces antibodies which act like TSH and leads to increased basal metabloic rate, weight loss, sweating, etc.

Hormone produced by the heart that lowers blood pressure


Physiologic doses of this hormone cause gluconeognesis. Pharmacologic doses depress the immune system

Corticosteroids, glucocorticoids

Name the mechanism systems for steroid hormone action

Gene Activation

The mechanism systems for amino acid hormone action


the hormone that is relesased in response to low blood sugar



the condition caused by excessive clinical adminstration of cortisone or glucocorticoids characterized by persistent hyperglycemia, losses of muscle and bone protein, water and salt retention, resulting in mooned face


excessive urine output


excessive thirst


excessive appetite

Humoral stimuli

Hormones secreted in direct response to changing blood levels of specific ions and chemicals

Neural stimuli

Nerve impulses (AP's) stimulate hormone release

Hormonal Stimuli

One hormone promotes the release of another hormone

Mineralo corticoids

Mineral and water balance; sodium retention; aldosterone


Gluconeogenesis; Energy metabolism, anti inflammatory,immune suppression


Sex hormones
