Ions, small solutes, lipid solubule materials use gap junctions for this type of communication |
direct |
|
This type of communication is used by ions, small solutes, lipid soluble materials |
Direc |
|
This communication occurs through extracellular fluid and involves paracrine factors |
paracrine |
|
This communication is limited to a local area, where paracrine factor concentrations are relatively high. Target cells must have appropriate receptors |
Paracrine |
|
This communication occurs through the blood stream and involves hormones |
Endocrine |
|
This communication targes cells primarily in other tissues and organs and must have appropriate receptors |
Endocrine |
|
This communication occurs across synapses via neurotrasmitters |
Synaptic |
|
This communication is limited to a very specific area, target cells that have appropriate receptors |
synaptic |
|
Three types of hormones are: |
Amino acid peptide Lipid Derivatives |
|
Examples of amino hormones |
Tyrosine and Tryptohan |
|
Examples of peptide hormones |
glycoprotiens and short polypeptides |
|
Examples of Lipid protiens |
Eicosanoids and Steroid hormones |
|
What three mechanisms does the hypothalmus use to control endocrine system |
Production of OXT and ADH Secretion of regulatory hormones Control of Synpathetic output to adrenal gland |
|
This ________ is an endocrine gland with _________ and _______ lobes and is called _________. |
anterior posterior hypophysis |
|
The anterior lobe of the pitutary gland is _________ and has three regions called ________, ___________ and ____________. |
adenohypophysis Pars tuberalis Pars intermedia Pas distalis |
|
The capillaries in the median eminence of the hypothalmus are supplied by the _________ |
fenestrated capilliaries |
|
Blood vessels that link two capillary networks are called_________. The hypothalmus portal system is called ______________. |
portal Hypophyseal |
|
What are the two hypothalmic regulatory hormones called______________ |
Release and inhibiting hormones |
|
What type of Hypothalmic hormone stimulates production by other glands |
releasing |
|
TSH |
Thyroid Stimulating Hormone aka Thyrotropin |
|
TRH |
Thyrotropin-releasing hormone |
|
TSH is relased in response to what form the hypothalmus |
TRH |
|
ACTH |
Adrenocorticotropic hormone aka Corticotropin |
|
This stimulates the release of steroid hormones by the adrenal gland_____________ and targests _____________ that affect glucose metabolism. ___________ from the hypothalmus stimulates this steroid hormone. |
ACTH glucocorticoids Corticotropin releasing hormones |
|
This _____________ regulates the gonads. |
Gonadotrophins |
|
The hypothalamus releases the hormone _________ which stimulates production of (GnRH) |
Gonadotrophin |
|
Low production of Gonadotrophin is called |
Hypogonadism |
|
Children with Hypogonadism do not mature ________ and adults cannot produce functional __________. |
Sexually Sperm |
|
The two gonardotropins are |
Follicle Stimulating Hormone (FSH) Luteinizing Hormone (LH) |
|
LH |
Luteinizing Hormone |
|
FSH |
Follicle Stimulating Hormone |
|
PRL |
Prolactin |
|
TSH, ACTH, FSH, LH, GH, PRL and MSH are released are controlled by the ___________ and are released from what lobe of the pituitary gland _________ and are considered what type of hormones. |
hypothalmus anterior lope releasing |
|
This hormone induces ovulations and promotes secretion of what two hormones |
LH estrogen progestrogen |
|
Male sex hormones stimulated by LH are called |
adrogens |
|
This stimulates mammary gland development and stimulates milk production |
PRL aka prolactin |
|
GH |
growth hormone aka somatrtropin |
|
This hormone stimulates growth and repair by acceleration the rate of protien synthesis. |
GH |
|
This stimulates breakdown of adipocytes, Stem cell division and in liver breakdown of Glycogen |
GH |
|
Production of GH is regulated by |
Growth releasing hormone (GHRH) and growth inhibiting hormone (GHIH) |
|
The posterior lobe of the pituitary gland is called the ____________ contains axons of ______________ |
Neurohypophusis hypothalmic neurons |
|
Neurons of the posterior pituitary manufacture what two hormones ______ |
Antidiuretic hormone (ADH) Oxytocin (OXT) |
|
ADH is aka |
vasopressin (VP) |
|
alcohol inhibits __________ release |
ADH |
|
This stimulates idoine transport into folicle cells and stimulates release of thyroid hormones |
THS |
|

T4 |
|
alled About 75% of T4 molecules and 70% of T3 Molecules enter the blood stream and become attached to transport protiens |
