1) Describe the steps of a secondary messenger system and characteristics of the system?

2) Also describe how levels of the end stage hormones control secretions of the hypothalamus through a negative feedback homeostatic and how that determine the levels of the stage hormone?

Homework Answers

Answer #1

1)

Secondarymessenger system is the process of how intracellular signalling occurs in response to exposure to extracellular signalling molecules.

Steps is as below:-

2.

Negative feedback occurs when there is increased hormones levels than requirement.

Negative feedback homeostasis is as below:-

You are assessing a patient who presented with intersex genitalia. You find that this individual is genetically male (has one X chromosome and one Y chromosome) and possesses the testis-determining factor (called the SRY gene). Further, they are producing adequate levels of gonadotropin-releasing hormone, follicle-stimulating hormone, and testosterone. What is the most likely explanation for this individual’s intersex genitalia? A.absent or inactive testosterone receptors B.hyposecretion at the level of the hypothalamus C. hyposecretion at the level of the testes D....

What does the follicle-stimulating hormone (FSH) do? A. Follicle-stimulating hormone is secreted by the hypothalamus in response to gonadotropin-releasing hormone sent from the gonads. FSH induces ovulation. B. Follicle-stimulating hormone is secreted by the anterior pituitary in response to gonadotropin-releasing hormone sent from the hypothalamus. FSH induces gamete development. C.Follicle-stimulating hormone is secreted by the posterior pituitary in response to leutenizing hormone sent from the hypothalamus. FSH induces Leydig cell formation.
