The Reproductive System
| Question | Answer |
|---|---|
| Female essential organs | Ovaries |
| Females are born | With eggs for their lifetime. |
| Corpus luteum | Forms after ovulation produces progesterone |
| Oogenesis | Meiotic cell division which produces daughter cells with equal chromosomes but unequal cytoplasm |
| Granulosa cells | Produce estrogen |
| Fimbraie | Fringe-like projections in the uterine tubes |
| Uterus 3 sections | Fundus, Body, Cervix |
| Body | Main part of the uterus |
| Cervix | Narrow lower part where vagina meets the uterus |
| Layers of the uterus | Perimetrium, Myometrium, Endometrium |
| Perimetrium | Thin shiny membrane surrounds the myometrium |
| Endometrium | Layer that sheds during menses and builds back up. |
| Bartholin Gland | Lies between labia major and labia minora and secretes mucus like lubricating fluid. |
| Breasts | Lie over the pectoral muscles, size is determined by fat content and has lactiferous ducts that drain at the nipple. |
| External Genitalia | Mons pubis, labia majora, labia minora, clitoris, hymen |
| Menstrual cycle | 28 days |
| 1st phase | Day 1-5, endometrial lining sheds off. |
| 3rd phase | Day 14-ovulation, FSH and LH secreted |
| 4th phase | Day 15-28 Secretory phase between ovulation and next menses, endometrium thickens. |
| PMS | Pre-menstrual syndrome- headaches, bloating, cramping, fatigue |
| Dysmenorrhea | Painful menses |
| TSS | Toxic Shock Syndrome-Infection caused by lack of changing tampon at least every 4 hours. |
| PID | Pelvic inflammatory disease |
| Yeast Infection | AKA vaginitis-occurs after taking antibiotics, wearing tight underwear |
| Fibromyoma | Benign tumors of the uterus called fibroids. |
| Ovarian Cyts | Benign fluid filled enlargements-painful |
| Ovarian Cancer | Most often a metastasis from somewhere else (breast or uterus) |
| Cervical cancer | Caused by HPV virus |
| Breast Cancer | Treated with lumpectomy or mastectomy. |
| Male essential organs | Testes |
| Testosterone | Made in the interstitial cells and is a masculinizing hormone that develops hair growth, low voice, muscle definition. |
| Sperm | Made in the semi nephrous tubules |
| Flagella | Tail of the sperm used for motility. |
| Semen | Fluid that allows the sperm to survive |
| Bulbourethral gland | Cowpers gland, size of a pea and empty their secretions into the penile portion of the urethra and contribute less than 5% of seminal fluid volume. |
| Prostate gland seminal fluid | Thick milklike fluid and acts as a lubricant for sperm helping to maintain their motility |
| Bulbourethral gland seminal fluid | Mucus-like secretions decrease friction damage to the sperm at the time of ejaculation. |
| Ejactulary duct | Urethra |
| Penis columns | One corpus spongiosum-surrounds the urethra, two corpora cavernosa-lie above |
| Foreskin | End of the penis |
| Sterility | No chance of reproducing |
| Oligospermia | Low sperm count, leading cause of infertility. |
| Inguinal Hernia | Protrusion of abdominopelvic organs through the inguinal canal into the scrotum |
| Benign Prostatic Hypertrophy | BPH-Enlarged prostate, stays soft, frequent urination at night (male) |
| Nocturia | Frequent urination at night |
| Phimosis | Tight foreskin-non circumcised |
| Paraphimosis | Foreskin gets stuck-non circumcised |
| Impotence | Erectile Dysfuction-unable to achieve erection |
| Hydrocele | Scrotal swelling, water blister on inside |
| Hypospadius | Opening is underside (male) |
| Epispadius | Opening is upperside (male) |
