The Hypothalamus is the
a. master gland
b master control center
c master organ
master control center
The pituitary is the
a master gland
b master control center
c master organ
master gland
Posterior pituitary produces 2 hormones true or false
false- It releases 2 hormones ADH and OT, but does not produce any hormones.
What does the endocrine system secrete
hormones
The nervouse system has a
fast response time
slow response time
fast
The endocrine system has a
fast response time
slow response time
slow
what does the endocrine system do
maintains blood comositions
cntrl reproductive activities
regulate development growth and metabolism
control the digestive process
is the endocrine system localized or wide spread
widespread
What are the major endocrine glands
pituitary gland (attached to the hypothalamus) pineal gland (attached to the thalamus) thyroid gland(in Neck) parathyroid gland (In neck) adrenal gland(attached to kidneys)
Organs that contain endocrine cells
hypothalamus Skin Thymus Heart Stomach Kidney Ovaries, testes and Placenta
What is a tropic hormone
hormones that stimulate other endocrine glands or cells to secret other hormones.
anterior pituitary hormones
TP-FLAG Thyroid stimulating hormone TSH- Prolactin- PRL Follicle stimulating hormone FSH Adrenocorticotropic hormone ACTH Growth Homrnone GH Melanocyte stimulating hormone MSH
TSH
Thyroid stimulating hormone
regulates the release thyroid hormone
PRL
prolactin-regulates mammary gland growth, milk production
FSH
Follicle stimulating hormone regulates hormone synthesis by the gonads
ACTH
adrenocorticotropic stimulates the adrenal cortex to produce and secrete glucocorticoids
GH
Growth hormone cell growth and cell division and this affects most body cells
MSH
melanocyte stimulating hormone regulates the distribution of melanocytes in the skin
What are the 3 types of hormones
Steroid
Protein
Biogenic amines (monomines)
Do steroid proteins need a carrier protein
yes, they are hydrophobic
Protein hormones
chains of amino acids
most hormones are in this group
Hydrophillic
Do protein hormones need a carrier protein
no, their half life is short
Are protein hormones able to enter the target cell
no, they must bind to the receptors in the cell membrane of the target cell and this initiates the appearance of a 2 messanger in the cytoplasm
What are biogenic amines derived from
tyrosine or tryptophan.
What hormones do the hypothalamus produce?
TRH, PRH, PIH, GnRH, CRH, GHRH Anpit
OT and ADH are store in the post pit
