To draw: A diagram illustrating hormone interactions during the preovulatory phase.
Introduction: Reproductive system (or genital system) is involved in sexual reproduction. The normal sex cycle including the ovarian follicle development, rupture of follicle, ovum discharge, and formation and regression of corpus luteum is called the ovarian cycle. The timing of the maturation of oocyte is controlled by this cycle. The ovarian cycle consists of three phases, namely the preovulatory phase, late preovulatory phase, and postovulatory phase.
To determine: The specific actions of FSH.
Introduction: Reproductive system (or genital system) is involved in sexual reproduction. The male and female reproductive systems’ function is to propagate the species. The normal sex cycle including the ovarian follicle development, rupture of follicle, ovum discharge, and formation and regression of corpus luteum is called the ovarian cycle.
To determine: The specific actions of estrogens.

- In Modules 2 and 3, we have discussed many different hormones and the mechanisms in which these hormone levels are regulated. Many hormones, including FSH, LH, progesterone, and estrogen are controlled through a negative feedback system. Although higher levels of estrogen in the follicular stage suppress the secretion of FSH and LH in the anterior pituitary, there is an LH spike at day 14 (ovulation).Can you provide an explanation as to why an LH/FSH spike may occur using the estrogen feedback loop?arrow_forwardDoes the following table properly summarize negative feedback loop of each tropic hormone? If not, place the correct answer beside each box.arrow_forwardName three anterior lobe hormones that have reproductive functions and three that have nonreproductive roles.What target organs are stimulated by each of thesehormones?arrow_forward

- Compare and contrast how the endocrine and neural systems do long- distance communication within the mammalian body. State and be able to recognize the roles of neurons and various types of glia (astrocytes, oligodendrocytes, Schwann cells, microglia). Give two mechanisms for how different target cells exposed to the same hormone can respond in different ways. Predict how perturbations to the hypothalamus, pituitary gland, thyroid, the hormones they secrete, or iodine levels will affect hormone levels, thyroid size, metabolic rate, and intelligence in children. Distinguish between asexual and sexual reproduction. Discuss how the environment, sex chromosomes, sex- determination genes, hormone levels, and anatomical features can contribute to sex determination in people or other organismarrow_forwardWhich of these assertions about hormones is not accurate? Which of these assertions about hormones is not accurate? A.)Hormones produced by the hypothalamus are considered neurohormones. B.) Cortisol is released in response to the release of ACTH from the pituitary. C.) Hormonal changes during puberty and pregnancy are forms of endocrine disruption. D.)
