Chapter 25 Reproductive System Flashcards

1
Q

Sex organs/genitalia

A
  • primary sex organs (gonads)- produce sex cells (gametes): in males: testes produce sperm; in females: ovaries produce an ovum (egg)

Accessory sex organs- all other aspects of the repro anatomy that nourish and transport the gametes + external genitalia

Q

Scrotum

A
  • testes are housed in scrotum, a sac-like structure of skin and superficial fascia
  • dartos muscle- layer of smooth muscle which crinkles scrotal skin to increase thickness
  • cremaster muscles- bands of skeletal muscle that extend inferiorly from internal obliques and elevate testes

Cremaster muscles elevate testes in cold and descend in hot
Dartos muscle uncrinkles in hot (for cooling) and wrinkles in cold

Q

Accessory Glands

A
  • Seminal vesicles-posterior and superior to urinary bladder; duct meets with ampula of vas deferens to become ejaculatory duct (which dumps into prostatic urethra); source of ~60% of seminal fluid
  • Prostate- encircles first part of urethra just inferior to urinary bladder; source of ~30% of seminal fluid
  • Bulbourethral glands- pea-sized glands inferior to prostate; lubricates urethra and neutralizes acidic urine in urethra

Q

Penis

A
  • external genitalia: penis/scrotum
  • Parts of penis:
    Root- attached to body; formed by the crus- attachment of corpora cavernosa to pubic bones
    free body- not attached to body
    glans penis- enlarged tip of shaft

Q

Internal erectile tissue of penis

A
  • Cylindrical bodies of erectile tissue: CT tube filled with sponge-like network of smooth muscle, CT, and vascular spaces
  • Corpus spongiosum (unpaired-ventral): surrounds the spongy urethra; forms the glans penis distally; forms the bulb of the penis (middle of root)
  • Corpus Cavernosum (paired-dorsal)- form the crura/crus (lateral parts of root)

Q

Walls of Uterus (3 layers)

A
  • Perimetrium - outer, serous membrane (peritoneum)
  • myometrium- bulky, middle layer of smooth muscle tissue
  • endometrium- mucosal lining of uterine cavity that is a functional layer nearest the lumen (shed during menstruation) with a basal layer that forms a new functional layer after menstruation

Q

External genitalia (vulva)

A
  • mons pubis- rounded fat pad over the pubic symphysis
  • labia majora- fatty, hair-covered skin folds extending posteriorly from mons pubis
