| Question | Answer |
|---|---|
| Aromatase | an enzyme that converts androstenedione to estrogen. |
| Granulosa cells | a group of cells lining the ovarian follicle which become part of the corpus luteum after ovulation. |
| Ovarian cycle | a series of changes in the ovary that results in maturation of a follicle, shedding of the ovum, and development of the corpus luteum. |
| Edometrium | a mucous membrane that lines the uterus and thickens during the menstrual cycle in response to progesterone and in preparation for implantation of an embryo |
| Corpus luteum | an endocrine structure that develops in an ovary in response to luteanizing hormone after an ovum has been discharged but degenerates after a few days unless pregnancy has begun. |
| Follicular phase | phase of the ovarian cycle during which follicles in the pvary mature. This phase ends with ovulation. |
| Luteal phase | phase of the ovarian cycle during which corpus luteum is formed in response to a rise in lutenizing hormone and progesterone. |
| Oestrogen | a sex hormone that regulates many bodily functions and behaviors including production of eggs, development of follicles, secondary sexual characteristics, and estrus. |
| Progesterone | a steroid sex hormone produced by the corpus luteum in order to prepare the uterus for conception. During pregnancy, it protects the embryo and fosters growth of the placenta. |
| Atresia | breakdown of the ovarian follicles, which consist of an oocyte surrounded by granulosa cells and theca cells. |
| Human chorionic gonadotropin (hCG): | is a placental hormone that binds to LH receptors in the corpus luteum and stimulates luteal cells to produce oestradiol and progesterone. |
| Oocyte | a cell from which an egg or ovum develops by meiosis; a female gametocyte. |
| Ovulation | release of a secondary oocyte from the graafian follicle. |
| Relaxin | a hormone produced by the corpus luteum and the placenta during pregnancy. It facilitates birth process by softening and lengthening the pubic symphysis and cervix. |
| Theca cells | In response to luteinizing hormone, produce androstenedione that is converted by aromatase into 17β estradiol to supply the granulosa cells with estradiol. |
| Zona pellucida | the transparent, noncellular, secreted layer surrounding an ovum. |
| ZP3 | receptor in the zona pellucida which binds sperm at the beginning of fertilization. |
| uterine/menstural cycle | cyclical changes in the endometial lining of the uterus in response to hormones to preparing for zygote implantation. |
