Hormones of the anterior Pit Flashcards
1
Q
where is the anterior pituitary located?
A
located in the brain beneath the hypothalamus- which will control the release of its hormones with releasing and inhibitory hormones of its own
2
Q
Which hormones does the anterior pit release?
A
1) hGH ( human growth hormone)
2) ACTH ( adrenocorticotropin)
3) TSH - thyroid stimulating hormone
4) FSH- follicle stimulating hormone
5) LH: leutonizing hormone
6) Prolactin
3
Q
HGH (Human growth hormone)
A
- peptide
- stimulates growth in almost all cells of the body . ( inc mitosis, inc cell size, inc protein synthesis rate, moving fat stores, dec use of glucose)
4
Q
ACTH ( adrenocortico tropic hormone)
A
- peptide
- stimulate the ADRENAL CORTEX to release glucocorticoids via secondary messenger system using CAMP.
5
Q
TSH ( thyroid stimulating hormone)
A
- is a peptide
stimulate the thyroid to release T3 and T4
T3 and T4 concentrations have a negative feedback effect on TSH release, both at the anterior pit and the hypothalamus
6
Q
Prolactin :
A
peptide promotes lactation (milk production) by breasts.
7
Q
Which other two peptide hormones are also made by the anterior pit?
A
FSH and LH
