Female Anatomy & Physiology

Menstrual Cycle

1.a Describe the how the structures of the endocrine system trigger different changes across the cycle.

1.b  What hormones are involved and where are these hormones produced?  

2. How do levels of estrogen and progesterone change across the menstrual cycle and why do they change?

3.a How do level of luteinizing hormone (LH) and follicle stimulating hormone (FSH) change across the menstrual cycle?

3.b What are the consequences of these changes?

4. When does ovulation occur in this cycle?

5. How does a woman's basal body temperature as well as cervical and vaginal fluid change during the menstrual cycle?

6. Mons veneris, clitoral gland, labia majora, labia minora, anus, vaginal opening, urethral opening, Prepuce of clitoris, vagina, fallopian tube, ovaries, uterus, cervical canal, fimbriae, and isthmus.

Understand the function and composition of the above structures:  what they are, where they are located, where they are produced, what they do > for all the above structures.

Explanation / Answer

1a. Endocrine and nevos system are involved in menstrual cycle. Gonadotropin hormone causes release of follicle stimulating hormone (FSH) and leutinizing hormone (LH) from pituitary gland. FSH stimulates development of maturing ovarian follicle and controls ova production. LH stimulates the ovaries to produce estrogen and progesterone. Estrogen helps in maturation and release of ovum. Progesterone helps in preparing the endometrium for the development of fertilized ovum.

1b. FSH and LH are produced by pituitary gland in brain. Estrogen is produced by ovaries and progesterone b corpus luteum in ovaries.

2. During follicular phase, pituitary gland will produce FSH and LH. During luteal phase, corpus lutem will poduce preogesteone and small amount of estrogen and in menstrual phase, corpus luteum will degenerate and progesterone levels will decrease.

3a. IN follicular phase of menstual cycle, LH and FSH were produced by pituitay gland and in luteal phase progesteone inhibits further release of FSH and LH.
