I really have no clue but gonna give it a shot
1) A problem with the hypothalamus has caused it to reduce the signals sent to the anterior pituitary to instigate the secretion of the growth hormone , causing less growth hormone to be secreted.
2) the child may have low glucose blood levels due to malnutrition causing the majority of the growth hormone to follow the chemical pathways which results in an increase in blood glucose levels, hence, less growth hormone follows the pathway in which cartilage growth and bone and tissue growth is instigated causing the child to have growth deficiencies
3) idk lol no clue
most of this was BS but i would like to see if i hit some targets
.
First answer is one the money. Second isn't a bad idea, but hormones really don't have a lot of choice in what they do. If it's increasing blood glucose, it's also increasing growth.
1)The boy has high stress and cortisol levels resulting In the hypothalamus not triggering the release of GH by anterior pituitary gland
2)The boy is malnutrition(ed?) and does not eat enough resulting in the hypothalamus not triggering the release of GH by anterior pituitary gland
3)Receptors on some or most bone and muscle cells responsible for attaching to growth hormone and initiating the 'growth' response are not properly shaped complementory to the growth hormone, thus causing the inability of the 'growth' response
Full guessed but hopefully i hit at least 1 of the marks.
1. Good
2. Malnourished is the way to say it :p not a bad idea, not sure if it's right though. Malnutrition causes these issues because you simply don't have enough energy to grow.
3. Really good too (and a common cause of problems with growth hormone; it even has a name: Laron Dwarfism).
Other options:
-too much somatostatin
-IGF-1 doesn't work
-anti-GH antibodies are circulating
-hypothalamus isn't producing GHRH
