"The corpus luteum synthesizes progesterone, estradiol, and 17-hydroxyprogesterone. The increased progesterone levels affect the thermoregulatory site in the hypothalamus and increase the core body temperature. Negative feedback from the increased release of estradiol and progesterone from the corpus luteum results in decreased serum LH and FSH levels in the luteal phase. If conception has not occurred, FSH levels increase again at the end of the luteal phase as the progesterone and estradiol levels decrease. The decrease in progesterone and estradiol levels results in shedding of the endometrium-i.e., menstruation. LH pulse frequency is high (90 minutes) and of low amplitude in the follicular phase. The pulse frequency and amplitude increase immediately before ovulation".
Progesterone plays a role in feedback mechanisms by interacting with the hypothalamus and anterior pituitary gland to regulate its own production. High progesterone levels inhibit the release of gonadotropin-releasing hormone (GnRH) which in turn decreases the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), ultimately reducing progesterone production. Low levels of progesterone have the opposite effect, leading to increased GnRH release and subsequently higher progesterone levels.

What is the mechanism called when a variation outside of normal limits triggers an automatic response that corrects the situation?
This mechanism is called homeostasis. It involves the body's ability to regulate and maintain stable internal conditions even when faced with external changes or challenges. Feedback loops play a key role in detecting deviations from the normal range and triggering corrective actions to return the body to a state of balance.
Is progesterone a carbohydrate?
No, progesterone is not a carbohydrate. It is a steroid hormone that plays a role in the menstrual cycle, pregnancy, and other bodily functions.
Which hormones are at their highest levels in the blood when the uterine lining is the thickest?
Estrogen and progesterone are at their highest levels in the blood when the uterine lining is the thickest. These hormones play a crucial role in thickening the endometrium, preparing it for potential implantation of a fertilized egg.
What is the target organ for progesterone?
The target organ for progesterone is the uterus in females. Progesterone plays a key role in preparing the uterus for implantation of a fertilized egg and maintaining a healthy pregnancy.
What is a mechanism functioning to maintain a stable internal environment is most likely to involve?
Homeostasis is a mechanism that functions to maintain a stable internal environment in our body. This process involves various physiological processes that regulate factors such as body temperature, blood pressure, and pH levels to keep them within a narrow range conducive to life. Hormones, nervous system feedback mechanisms, and organ systems like the kidneys and liver all play a role in maintaining homeostasis.
What role does the oestrogen and progesterone play in the menstrual cycle?
It causes you to poo out your mouth and have your period out your ear! so painful

Is it impossible to keep your body chemistry in balance without some sort of negative feedback mechanism?
Negative feedback mechanisms are essential for maintaining homeostasis in the body by responding to changes and restoring equilibrium. Without these mechanisms, it would be challenging to regulate functions such as temperature, pH levels, and hormone levels, leading to potential imbalances and health issues. Thus, negative feedback mechanisms play a crucial role in keeping the body's chemistry in balance.

Will progesterone develop secondary sexual organs at puberty in a female?
No, progesterone does not play a significant role in the development of secondary sexual organs in females during puberty. The primary hormones involved in the development of secondary sexual characteristics in females are estrogen and testosterone.
Which hormones regulates the uterine lining?
In the menstrual cycle, estrogen and progesterone are the hormones that play a critical role in regulating the development and shedding of the uterine lining. Estrogen stimulates the growth of the uterine lining, while progesterone helps maintain it and prepares it for a potential pregnancy.
What is the role that feedback from your supervisor plays or will play in your instruction?
Feedback from your supervisor lets you know the areas that you excel in and also, the areas that you need additional instruction in. Negative feedback from a supervisor should not be taken personally, but as a learning tool with ways you can improve your performance.
Is progesterone considered a hormone?
Yes, progesterone is considered a hormone. It is produced primarily in the ovaries (in women) and plays a crucial role in regulating the menstrual cycle and supporting pregnancy.
What is progesterone's target cell?
Progesterone's target cells are primarily found in the reproductive system, such as the uterus and mammary glands. In these cells, progesterone plays a key role in regulating the menstrual cycle, supporting pregnancy, and preparing the body for breastfeeding.
