Portage A&P1 Module 6 Exam
Explain two reasons why a woman with low levels of LH would not be able to
become pregnant.
(1) LH acts on the ovary to cause ovulation to occur. (2) LH causes progesterone
release to facilitate potential fertilization of the egg and pregnancy. Progesterone
is a key hormone for the maintenance of pregnancy.
We have an expert-written solution to this problem!
Would you expect a female to have testosterone in their bloodstream? Explain
why or why not.
(1) Yes. Both male and female bodies produce "all" the sex hormones. However,
the ratios are different.(2) The adrenal glands are largely responsible for
producing this "opposite" hormone that the ovaries would not.
Label the endocrine glands (A-D)
A: ______________B: ______________C: ______________D: ______________
A. thyroid gland
B. adrenal gland
c. kidney
d. pancreas
,Explain the concept of positive feedback. Give an example of a hormone that
works through positive feedback.
1- Positive feedback is the action of a hormone increasing the production of that
hormone. (This is the opposite of negative feedback).
2- One example is the action of oxytocin causing the uterus to contract during
labor. Oxytocin enhances the effect of the uterus contractions, causing more
oxytocin to be released. The positive feedback loop is stopped once the baby is
born and the uterus no longer needs to contract, stopping the production of
oxytocin.
This type of hormone is derived from cholesterol:
Steroid hormones
Growth hormone:
Is produced by the anterior pituitary gland
Neurosecretory cells are a part of what endocrine organ?
Hypothalamus
Which hormone production is increased with sunlight?
MSH (melanocyte stimulating hormone)
,The posterior pituitary stores these two hormones:
ADH and Oxytocin
List the hormone(s) that best describes the statement below:
I promote the reabsorption of water at the collecting ducts of the kidneys.
ADH
List the hormone(s) that best describes the statement below:
I am secreted by the pituitary and stimulate the gonads.
FSH & LH (gonadotropic hormones)
List the hormone(s) that best describes the statement below:
I am secreted by the pituitary to stimulate the adrenal cortex.
ACTH
List the hormone(s) that best describes the statement below:
, I cause blood glucose to rise and breakdown stored nutrients.
Glucagon
Answer the following question.
Explain why it would be harmful to have an increased secretion of ACTH in
someone who is diabetic.
ACTH controls the secretion of cortisol from the adrenal cortex. Increased levels
of ACTH would cause increased levels of cortisol within the blood.
Cortisol increases blood glucose levels which will decrease the effectiveness of
insulin treatments.
Where is the thyroid stimulating hormone produced?
Anterior Pituitary gland
Which cells mature in the thymus?
T cells
Iodine is needed to produce which hormone/s?
E. B & C
