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 a??egga?? 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
