| Question | Answer |
|---|---|
| What is the location of the myoid cells of the testes? | They surround the seminiferous tubules. |
| What is the function of the myoid cells in the testes? | Contracts rhythmicalLy to propel sperm and testicular fluids theough the tubes. |
| What organ that delivers semen to the female reproductive tract? | Penis |
| Where is the site of sperm and testosterone production? | Testis |
| What is the passageway for conveying sperm from the epididymis to the ejaculatory duct? | Ductus deferens |
| What conveys both sperm and urine down the length of the penis? | Urethra |
| What 4 organs contribute to the formation of semen? | Bulbo-urethral glands, prostate, seminal glands, testis |
| External skin sac that houses the testes | Scrotum |
| Tubular storage site for sperm; hugs the lateral aspect of the testes | Epididymis |
| Cuff of skin encircling the glans penis | Prepuce |
| Surrounds the urethra at the base of the bladder; produce a milky, slightly acid fluid | Prostate |
| Produces over half of the seminal fluid | Seminal gland |
| Empties a lubricating mucus in the urethra | Bulbo-urethral gland |
| Connective tissue sheath enclosing the ductus deferens, blood vessels, and nerves | Spermatic cord |
| What is the pathway of sperm from the testis to the urethra | Seminiferous tubule-> rate testis -> epididymis -> ductus deferens -> ejaculatory gland |
| Spongy tissue that is engorged with blood during erection | Corpus cavernosum and spongiosum of the penis |
| Portion of the duct system that also serves the urinary system | Urethra |
| Structure that provides the ideal temperature conditions for sperm formation | Scrotum |
| Structure cut or cauterized during a vasectomy | Ductus deferens |
| Gland whose secretion contains sugar to nourish sperm | Seminal gland |
| What cells aid in this process by disposing of excess cytoplasm and providing nutrition to the mature sperm? | Sustenocytes |
| Chamber that houses the developing fetus | Uterus |
| Canal that receives the penis during intercourse | Vagina |
| Usual site of fertilization | Uterine tube |
| Becomes erect during sexual stimulation | Clitoris |
| Duct through which the ovum travels to reach the uterus | Uterine tube |
| Membrane that partially closes the vaginal canal | Hymen |
| Primary female reproductive organ | Ovary |
| Move to create fluid currents to draw the ovulated âeggâ into the uterine tube | Fimbriae |
| Forming part of the primary follicle of the ovary | Prima oocyte |
| In the uterine tube before fertilization | Secondary oocyte |
| In the antral, or graafian, follicular of the ovary | Secondary oocyte |
| In the uterine tube shortly after perm penetration | Ovum |
| Promotes growth of ovarian follicles and production of estrogen | FSH |
| Triggers ovulation | LH |
| Inhibit follicle-stimulating hormone (FSH) release by the anterior pituitary _______&_________ | Estrogen and progesterone |
| Stimulates luteinizing hormone (LH) released by the anterior pituitary | High concentration of estrogen or GnRH |
| Converts the ruptured follicle into a corpus luteum and causes it to produce progesterone and estrogen | LH |
| Maintains the hormonal production of the corpus luteum | LH or hCG |
