There are two I could not find. Are those that I have so far correct?

1. Name the hormone that triggers development of a primary follicle. I had no idea. . .

2. The corpus luteum releases progesterone in the luteal phase.

3. Oestrogen and progesterone are two hor mones that cause the uterine lining to increase.

4. Luteinizing hormone spikes cause ovulation?

5. Days 16 to 28 are the secretory phase.

6. Upon pregnancy, progesterone and estrogen levels are high and this provides negative feedback to the ( fill in the blank?) to prevent future ovulation.

7. The developing follicle releases the hormone estrogen.

Im sure this is in the book on this section..

but i think (not sure) FSH is 1.

On #6, what part picks up on negative feedback and sends out the command to stop ovulating?

To check the accuracy of your statements, let's go through each one individually:

1. Name the hormone that triggers the development of a primary follicle.
The hormone that triggers the development of a primary follicle is follicle-stimulating hormone (FSH). FSH is secreted by the pituitary gland and plays a crucial role in the growth and maturation of ovarian follicles.

2. The corpus luteum releases progesterone in the luteal phase.
This statement is correct. The corpus luteum, which forms from the remains of the follicle after ovulation, secretes progesterone in the luteal phase of the menstrual cycle. Progesterone helps prepare the uterus for possible implantation of a fertilized egg.

3. Estrogen and progesterone are two hormones that cause the uterine lining to increase.
This statement is also correct. Estrogen and progesterone work together to promote the growth and maintenance of the uterine lining, also known as the endometrium. Estrogen stimulates the growth of the endometrial lining, while progesterone helps prepare and maintain the endometrium for pregnancy.

4. Luteinizing hormone spikes cause ovulation.
Yes, this statement is accurate. Luteinizing hormone (LH) surges trigger ovulation. The LH surge stimulates the release of the mature egg from the ovary, allowing it to be available for fertilization.

5. Days 16 to 28 are the secretory phase.
This statement is correct. In a typical 28-day menstrual cycle, the secretory phase occurs from approximately day 16 to day 28. During this phase, the endometrium prepares for implantation by increasing in thickness and becoming more vascularized.

6. Upon pregnancy, progesterone and estrogen levels are high, providing negative feedback to the (fill in the blank?) to prevent future ovulation.
In pregnancy, high levels of progesterone and estrogen provide negative feedback to the hypothalamus and pituitary gland, specifically the production of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH). This negative feedback prevents future ovulation and the development of a new follicle.

7. The developing follicle releases the hormone estrogen.
This statement is correct. As the follicle matures, it releases increasing amounts of estrogen. Estrogen plays a vital role in the menstrual cycle, influencing the growth of the uterine lining and regulating the production of other reproductive hormones.

Overall, your statements appear to be accurate based on the information provided.
