| Question | Answer |
|---|---|
| Each ovarian follicle consists of? | An oocyte encased by follicle cells or granulos cells (if many). |
| At what stage does follicle bulge from surface of ovary? | As a mature vesicular follicle - Graafian follicle. |
| What happens at ovulation? | When ripe follicle ejects its oocyte from ovary. |
| What does follicle become after ovulation? | Corpus luteum - left over glandular structure. |
| Where does fertilization usually occur? | In the ampulla of the fallopian (uterine) tubes. |
| Mesosalpinx | Mesentery that covers uterine tubes |
| 3 layers of uterus wall | out to in - perimetrium, myometrium, & endometrium. |
| The vagina is lubricated by the __. | cervical mucous glands, not the vaginal mucosa. |
| What gland moistens external vestibule of vagina? | Greater vestibular glands. |
| Breast cancer usually arises from __. | epithelial cells of the smallest ducts, not alveoli. |
| Where in meiosis is female oocyte "stalled"? | Late Prophase I |
| In the follicular phase of ovarian cycle __. | a primordial follicle becomes a vesicular follicle (Day 1 - 14). |
| LH stimulus causes __. | ovulation |
| Blood levels low in __ can delay puberty. | leptin |
| mittelschmerz | pain during ovulation |
| FSH exerts its main effects on ovary __. | follicle cells |
| __ exerts its main effects on ovary thecal cells. | LH - prompts these cells to produce androgens. |
| High estrogen levels cause __ surge, which stimulates the dominant follicle __. | LH - to complete first meiotic division |
| After ovulation __ levels decline. | Estrogen - due to rupture of dominant estrogen-secreting follicle. |
| Why is LH called a "luteinizing hormone"? | Because LH surge also transforms ruptured follicle into corpus luteum. |
| What is the hormone situation at beginning of menstrual cycle? | Ovarian hormones are at lowest normal levels & gonadotropins are beginning to rise endometrium detaches. |
| By day 5 __ are starting to produce more estrogen. | growing ovarian follicles |
| The corpus luteum releases __. | progesterone |
| Rising estrogen levels cause __. | epiphyseal closure |
| The source of progesterone & estrogen during most of pregnancy is __. | the placenta, not the ovaries. |
| Which hormone at root for female sex drive? | DHEA |
| Gonorrhea invades what? | The mucosae of reproductive & urinary tracts. |
| Symptoms of gonorrhea | Painful urination & discharge of pus from penis |
| Symptoms of syphilis | Chancre - lesion at site of bacterial invasion - ulcerates - pink rash all over body - fever & joint pain. |
| Most common bacterial STD. | chlamydia |
| Symptoms of chlamydia | urethritis, discharge, inner abdominal pain, arthritis, UTI |
| Gene on 4 chromosome that initiates testes. | SRY gene |
| In embryo, the genital tubercle can become __. | glans penis or glans clitoris |
| cryptorchidism | failure of testes to drop |
| gynecomastia | development of breast tissue in male |
| orchitis | inflammation of testes |
| salpingitis | inflammation of uterine tubes |
