| When the graffian follible is developed it is now referred to as an _ _ _ _ or _ _ _ _ _ _ _ _ _ follicle | vesicular or graatian follicle |
| Define ovulation | when a mature egg ruptures from the ovary |
| Oh average how often does ovulation occur in terms of days? | 28 days |
| What is the covering of the ovum called? | corona radiata |
| How is this covering broken down? | (blank) |
| Define capacitation-why is it important? | it is the last step of sperm maturation that leads to the fertilization of the egg after ejaculation |
| List 3 stages of the ovarian follicle development | follicular; ovulation; luteal |
| Name 3 ligaments that support the ovaries | suspensory ligaments-secure ovary to lateral wall of the pelvis ovarian ligaments- attach to the uterus broad ligament- a fold of the peritoneum, encloses suspensory ligament |
| What are fimbriae? Why are they important? | finger like projections at the distal end that revieve the oocyte |
| Fertilization is to the ____ as implantation is to the uterus | fallopian tubes |
| Define an ectopic pregnancy | a pregnancy that occurs in the fallopian tubes |
| 5 facts about gonorrhea | females: causes yellowish discharge, bleeding during intercourse males: yellowish greenish discharge, pain urinating Leads to Pelvic inflamatory disease and scarring or closing of the fallopian tubes which leads to ectopic pregnancy |
| Uterus or ____ | womb |
| List 3 functions of the uterus | 1. recieves a fertilized egg 2. retains the fertilized egg 3. nourishes the fertilized egg |
| List the 3 walls of the uterus | endometrium-inner layer, allows for implantation of egg, sloughs off if no pregnancy occurs myometrium-middle layer of smooth muscle serous layer- outer visceral peritoneum (perimetrium) |
| Where does the cervix lead? | the vagina |
| HPV vaccine-What is it? | guardacil |

| Define menopause | the end of reproductive ability |
| What two key hormones regulate the "menstrual" cycle? | estrogen and progesterone |
| What are the three stages of the menstrual cycle? | menses-functional layer of the endometrium is sloughed proliferation-regeneration of functional layer secretory-endometrium increases in size and readies for implantation |
| What is the key function of estrogen? | enlargement of accssory organs, development of breasts, appearance of pubic hair, increase in fat beneath the skin, widening and lightening of pelvis, onset of menses |
| What is the key function of progesterone? | helps maintain pregnancy |
| Mammary glands are modified _____ | sweat glands |
| List 4 stages of pregnancy and development | 1. fertilization 2. embryonic development 3. fetal development 4. childbirth |
| Define zygote | first cell of a new individual result of fusion of DNA from sperm and egg |
| define cleavage | rapid cell development of the zygote |
| Define morula | solid sphere of 16 or more cells |
| Define blastocyte | 100 or more cells |
| zygote-time frame: from ___ to ___ | 12 hours |
| Embryo-Time frame: from ___ to ___ | start of cleavage-ninth |
| Fetus-Time frame: from ___ to ___ | (blank) |
| What is the function of the placenta? | 1. forms a barrier between the mom and embryo 2. delivers nutrients and oxygen 3. removes waste from embryonic blood 4. becomes an endocrine organ and takes over the corpus luteum-etrogen, progesterone, and other hormones |
