Endocrine case study lab

Question 1

Study diagram in lab notes to view the relationship between the hypothalamus, pituitary gland, and gonad involved in producing testosterone

Answer 1

JUST DO IT

Question 2

Hypothalamus actions with testosterone

Answer 2

produces GnRH, the gonadotropin releasing hormone

Question 3

Pituitary gland action with testosterone

Answer 3

produces follicle-stimulating hormone (FSH) and luteinizing hormone (LH)

Question 4

Gonads in actions with testosterone

Answer 4

steroid hormone production (testosterone!)

Question 5

How does testosterone regulate its own production?

Answer 5

signals from the hypothalamus to the pituitary gland, it relays signals to testes to produce testosterone

Question 6

What effect does testosterone regulating its own production have on the hypothalamic and pituitary hormones

Answer 6

there’s a feedback loop that creates a regulation of hormones in the blood

Question 7

In Klinefelter sydrome, testosterone levels are low because the testes themselves produce lower levels of testosterone; this is termed primary hypoandrogenism. In this case , what would be expected of pituitary hormone levels

Answer 7

levels will be low

Question 8

Kallman’s syndrome has low testosterone levels because the hypothalamus does not develop appropriately; what is to be expected of GnRH and LH concentrations?

Answer 8

prediction of low concentrations

Question 9

diagnosis for a patient

Answer 9

preliminary diagonsis (with alternative) with clues of the diagnosis and lab tests that will be ran to confirm it

final diagnosis with explanation of confirmation of the diagnosis from lab tests; explanation of lab test costs

finding a proper way to explain the diagnosis to the patient, such as why the endocrine disorder resulted in their symptoms and what effect is will have on the hormones in their body
