The Reproductive System and Human Development
| Question | Answer |
|---|---|
| Homologous structures of the male and female reproductive systems | testis/ovaries, vas deferens/uterine tube, scrotum/labia majora, glans penis/clitoris |
| Layers of the uterus from innermost to outermost | endometrium, myometrium, perimetrium |
| Secondary oocytes are frozen in | meiosis I |
| Functional tissue of the myometrium | smooth muscle |
| At about the 14th day of a woman's ovarian cycle | LH spikes promoting ovulation |
| The ovarian cycle always preceeds the uterine cycle by | 7 to 10 days |
| Phases of the ovarian cycle | follicular phase, ovulation, luteal phase |
| Weak contractions that are often mistaken for labor | Braxton Hicks contractions |
| The greater and lesser omentums are to the digestive system as this is to the reproductive system | mesosalpinx |
| To survive, an egg must be fertilized within ___ to ___ hours of ovulation | 12/24 |
| Amount of days sperm remains viable after ejaculation | 7 days |
| The "window of opportunity" | a few days before ovulation to 14 hours after |
| When the sperm encounters an egg, it undergoes an __________ reaction | acrosomal reaction |
| The conceptus is most vulnerable to stress, drugs, and nutritional deficiencies during | the first trimester |
| Spherical stage consisting of 16 or more blastomeres | morula |
| Single diploid cell formed by the union of egg and sperm | zygote |
| In the United States, the average life span for men and women | 75/81 |
| If an XX egg is fertilized by a Y-bearing sperm the result is an XXY combination | Klinefelter Syndrome |
| Embryological arrangement of the blastomeres into 3 primary germ layers during implantation | embryogenesis |
| The period from implantation through week 8 | trophoblastic phase |
| The degeneration that occurs in an organ system after the peak age of functional efficiency | senescence |
| The three stages of labor | dilation, expulsion, placental |
| Cells that secrete a layer of glycoprotein gel | granulosa cells |
| The linea _______ becomes the linea _______ due to an increase in melanocytes | linea alba/linea nigra |
| ______ prepares the uterus for pregnancy while _____ suppresses FSH secretion | progesterone/inhibin |
| Degeneration of glands, stroma and blood vessels | occurs during the premenstrual phase |
| During pregnancy, a woman’s levels of thyrotropin, prolactin and ACTH | increase |
| Factors does not increase the chance of having breast cancer | carcinogenic chemicals, smoking, menstruating earlier in life |
| Human chromosomes contain ___ pairs of autosomes and ___ pair of sex chromosomes | 22/1 |
| Carry sperm from the testis to the urethra | spermatic ducts |
| Hormone secreted by the hypothalamus at puberty | gonadrutropin releasing hormone (GnRH) |
| Site of sperm maturation that stores and conveys spermatozoa to the vas deferens | epididymis |
| The conversion of spermatids to spermatozoa | spermiogenesis |
| Secreted by the prostate gland into semen | alkaline secretion to aid the survival of sperm in the acidic atmosphere of the female reproductive tract, acid phosphatase,thin liquid that helps sperm become motile |
| When semen is discharged, about ______________ of the volume is made up of spermatozoa | 10% |
| Testosterone production is carried out by the ________ cells after being stimulated by ___________ | interstitial/luteinizing hormone |
| The entire process of spermatogenesis, from production of primary spermatocyte to release on immature cells | takes 68-74 days |
| Pathway that sperm follow when leaving the male body | Epididymis; ductus (vas) deferens; ejaculatory duct; prostatic urethra; membranous urethra; spongy urethra; urethral orifice |
| Gene that codes for the production of primary male hormone | SRY gene |
| Failure of the testes to descend | Cryptorchidism |
| The distal end of the phallux is called | glans penis |
| The regions of the urethra from posterior to superior are | penile urethra, membranous urethra and prostatic urethra |
| spermatogenesis takes place in | seminiferous tubules |
| The four things found in the spermatic cord are | Ducuts deferens, blood vessels, lymphatic vessels and testicular nerves |
| During which time period can you determine the sex of the baby | 5-6 weeks |
