Reproductive System - E3

Question 1

Perineum

Answer 1

diamond-shaped area containing external genitalia plus anus and external urethral orifice

Question 2

Primary sex organs

Answer 2

gonads - testes and ovaries
produce gametes (sex cells) - sperm and ova

Question 3

Accessory sex organs

Answer 3

Ducts - store and transport

Glands & Organs - mucus production, viscosity levels

Question 4

Male reproductive system

Answer 4

scrotum
testes
penis
accessory sex organs

Question 5

Scrotum

Answer 5

“bag”
out pocketing of abdominal wall
helps lower temp. for sperm production

Question 6

Dartos & Cremaster muscles

Answer 6

dartos - smooth muscle (wrinkling)
cremaster - skeletal muscle (can pull up scrotum)
both allow temp. control

Question 7

Testes

Answer 7

paired oval glands
develop in abdominal cavity but descend into scrotum
covered by tunica albuginea
subdivided into lobules
each lobule divided into 1-3 seminiferous tubules

Question 8

Tunica albuginea

Answer 8

dense, white fibrous c.t.

Question 9

What are leydig cells

Answer 9

interstitial cells that make testosterone in the testes

Question 10

Duct system of male reproductive system

Answer 10

1. seminiferous tubules
2. ductus epididymis
3. ductus (vas) deferens
4. ejaculatory duct
5. urethra

Question 11

Tissue component and function of:

1. ductus epididymis
2. vas deferens

Answer 11

pseudostratified columnar epithelia

1. sperm maturation; coiled
2. peristalsis; not coiled

Question 12

Semen

Answer 12

fluid + sperm

Question 13

Accessory sex glands

Answer 13

produce enzymes/buffers for female receptivity
seminal vesicles (2)
prostate
bulbourethral (2)

Question 14

Female reproductive system

Answer 14

1. Ovaries
2. Fallopian tubes
3. Uterus
4. Vagina
5. Vulva

Question 15

Ovaries

Answer 15

paired, flat ovals
produce ova and hormones
also has tunica albuginea

Question 16

Follicles

Answer 16

ovum + supporting cells

located in cortex of ovaries

Question 17

Uterus

Answer 17

womb
“metri”
“hyster-“

Question 18

Layers of uterus

Answer 18

1. perimetrium - serosa; visceral peritoneum
2. myometrium - smooth muscle
3. endometrium - simple col. epi.; c.t.; inner layer shed each month, outer retained

Question 19

Vagina

Answer 19

birth canal
tubular, fibromuscular organ
mucosa lined with strat. squamous epi.
rugae allow for expansion and stimulation

Question 20

Clitoris

Answer 20

erectile tissue w/prepuce

Question 21

Labia majora vs minora

Answer 21

Majora - lateral fold, fat, hair

Minora - medial enclosed vestibule, no fat, no hair

Question 22

Alternate names for uterine tubes

Answer 22

Fallopian tubes

Oviducts

Question 23

Uterine tubes

Answer 23

not directly attached to ovary

infundibulum w/fimbriae surrounds ovary

Question 24

How does the uterine tubes transport ova to the uterus?

Answer 24

1. Cilia lining the tubes - inward current

2. Smooth muscle - peristalsis

Question 25

How do the testes and ovaries compare?

Answer 25

• Both covered in tunica albuginea
• Both gonads
• both paired
• both produce gametes
• both develop internally, retroperitoneal
