CH. 27; REPRODUCTIVE SYSTEM (FINAL EXAM) QUESTIONS AND
ANSWERS.
What are the primary sex organs? - ANSWER: Gonads: Testes, and
ovaries.
What do Gonads produce? - ANSWER: Sex cells (gametes)
What do Gonads secrete? - ANSWER: Steroid sex hormones
What are the steroid sex hormones for males? - ANSWER: Androgens
What are the steroid sex hormones for females? - ANSWER: Estrogens
and Progesterone
What are accessory reproductive organs? - ANSWER: Ducts, glands, and
external genitalia
What do Sex Hormones play roles in? - ANSWER: Development and
function of the reproductive organs, sexual behavior and drives, and
growth and development of many other organs and tissues.
Where are the testes located? - ANSWER: Within the scrotum
What is the function of the testes? - ANSWER: Produce sperm.
,How are sperm delivered to the exterior? - ANSWER: Through a system
of ducts (Epididymis, ductus deferens, ejaculatory duct, and the urethra)
What are the accessory glands of the Male Reproductive System? -
ANSWER: Seminal vesicles, prostate, and bulbourethral glands.
What do the accessory glands do? - ANSWER: Empty secretions into the
ducts during ejaculation.
What are the testes surrounded by? - ANSWER: Two tunics.
What are the two tunics surrounding the tests? - ANSWER: Tunica
vaginalis, derived from peritoneum; and Tunica albuginea, the fibrous
capsule
What divides the testis? - ANSWER: Septa divide testes into 250 - 300
lobules, each containing 1 - 4 seminiferous tubules.
Where is the site of sperm production? - ANSWER: Seminiferous tubules
What are Sperm conveyed through? - ANSWER: Seminiferous tubules,
tubulus rectum, rete testis, efferent ductules, and the epididymis.
What is the blood supply of the testes? - ANSWER: Testicular arteries and
veins.
What encloses nerve fibers, blood vessels, and lymphatics that supply
the testes? - ANSWER: Spermatic cord.
, What is the scrotum? - ANSWER: Sac of skin and superficial fascia that
hangs outside the abdominopelvic cavity, contains the pair of testes
What is the temperature difference in the scrotum? - ANSWER: 3* lower
than core body temperature
Why is temperature regulation important? - ANSWER: Temperature
necessary to sperm production
Temperature is kept constant by what two sets of muscles? - ANSWER:
Smooth muscle that wrinkles scrotal skin (dartos muscle), and bands
of skeletal muscle that elevate the testes (cremaster muscles)
What is the male external genitalia? - ANSWER: Scrotum and penis
What is the male copulatory organ? - ANSWER: The penis
What does the penis consist of? - ANSWER: Root and shaft that ends in
the glans penis, prepuce, or foreskin, crura, the spongy urethra and
three cylindrical bodies of erectile tissue.
What is circumcision? - ANSWER: The surgical removal of the foreskin of
the penis
What is the crura? - ANSWER: The proximal end surrounded by
ischiocavernosus muscle; anchors penis to the pubic arch
What is the spongy urethra? - ANSWER: Spongy network of connective
tissue and smooth muscle with vascular space
