female reproductive system
| Question | Answer |
|---|---|
| ovaries,uterine tubes,uterus(womb),vagina,external genitalia | principle organs of the female reproductive system |
| produce female gametes(ova),secrete sex hormones,secrete inhibin | ovaries |
| mesentary that stabilizes each ovary | broad ligament, pair of supporting ligaments |
| encloses uterine tubes and uterus | mesentary |
| ovum production,begins before birth,accelerates at puberty,ends at menapause. | oogenesis |
| stem cells in ovaries, complete mitotic division before birth | oogonia |
| between 3rd and 7th month of fetal development they begin meiosis up to prophase 1 then stop | primary oocytes |
| how many oocytes survive out of the 2million at birth? | 400,000 |
| process where primary oocytes degenerate | atresia |
| the ovary does not release a mature gamete instead it releases a? | secondary oocyte |
| when is the second meiotic division occur? | after fertilization |
| sites of oocyte growth and meiosis 1 of oogenesis? | ovarian follicles |
| clusters of primary oocytes surrounded by a layer of follicle cells? | primordial follicles |
| oviduct/uterine tube, 5inches | fallopian tube |
| end closest to ovary, expanded funnel,has fingerlike projections that extend into pelvic cavity | infundibulum |
| the projections are called ? and are carpeted with cilia | fibria |
| involves combination of ciliary movements and peristaltic contractions by smooth muscles in the walls of uterine tubes | oocyte transport |
| how many days it takes for the oocyte to travel from infundibulum to uterine cavity | 3-4 days |
| cells in the epithelium lining the uterine tubes | ciliated,peg cells, mucin-secreting cells |
| project into the lumen of the uterine tube and secrete a fluid that both completes the capacitation of spermatozoa and supplies nutrients | peg cells |
| muscular chamber that provides mechanical protection and nutritional support for the developing embryo and fetus | uterus |
| 2 regions of the uterus | body,cervix |
| largest division of the uterus | body |
| rounded portion of the body | fundus |
| body of the uterus ends at the | isthmus |
| inferior portion of the uterus projects into the vagina | cervix |
| repeating series of changes in the structure of the endometrium | uterine cycle/menstrual cycle |
| first uterine cycle occurs with the ? | menarche |
| average length of the uterine cycle | 28days/can range 21-35 |
| menses,proliferative,secretory | 3 phases of the uterine cycle |
| degeneration of the superficial functional zone of the endometrium | menses |
| what is triggered by a decline in progesterone and estrogen levels as the corpus luteum disintegrates? | menses |
| lost of functional zone last 1to7days 1.7oz blood lost | menstruation |
| uterine inflammation,myometrial contractions, | painful menstruation or dysmenorrhea |
| follows completion of menses cells multiply and spread across endometrium | proliferative phase |
| uterine glands enlarge, endometrium prepares for the arrival of a developing embryo. begins at ovulation persist as the corpus luteum remains intact | secretory phase |
| elastic muscular tube extending between the uterus and the vestibule,3 to 3in long | vagina |
| shallow recess surrounding the cervical protrusion | fornix |
| elastic epithelia fold partially blocks the entrance to the vagina | hymen |
| inflammation of the vaginal canal | vaginitis |
| muscular floor of the pelvic cavity includes anus and external genitalia | perineum |
| perineal region enclosing the female external genitalia | vulva/pudendum |
| vagina opens into the ? central space bounded by the? | vestibule,labia minora |
| extensions of the labia minora that encircle the body of the clitoris | prepuce |
| prominent bulge formed by adipose tissue | mons pubis |
| encircle and partially conceal the labia minora | labia majora |
| specialized organs of the integumentary system controlled by hormones of the reproductive system and placenta | mammary glands |
| the most important estrogen | estradiol |
| coitus/copulation | sexual intercourse |
| occurs under sympathetic stimulation | emission |
| occurs by powerful contractions in the ichiocavernosus and bulbospongiosus muscles | ejaculation |
| subsidence of erection | detumescence |
| during sexual arousal leads to engorgement of erectile tissue | parasympathetic activation |
