Anatomy 2 Exam

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
