1

Primary sex organs are called

gonads

2

Primary sex organs of female are

ovaries

3

Primary sex organs of male are

testes

4

Female produces ______ oocytes monthly

1

5

Male produces _____ of sperm daily

100,000,000s

6

Sperm are stored and mature in

epididymis

7

If sperm aren't expelled from the body within a certain period, they are ____

resorbed

8

_____ produce large amounts of sex hormones which affect maturation, development, and changes in the activity of the reproductive system organs.

Gonads

9

Sex hormones in females

estrogen and progesterone

10

Sex hormones in males

androgens (testosterone and dihydrotestosterone)

11

Both males and females have accessory reproductive organs including ______ to carry gametes away from the gonads toward the site of fertilization

duct systems

12

Epididymis, Ductus (vas) deferens, Ejaculatory duct, and Urethra make up the ______

efferent duct

13

The seminal vesicles, prostate, and bulbourethral glands make up the

3 accessory glands

14

_______ are the primary gonads that produce and synthesize sperm and hormones

testes

15

is a fibromuscular cutaneous sac, located between the penis and anus.

scrotum

16

the site of sperm & testosterone production.

Testis

17

functions as a storage reservoir for sperm & site of sperm maturation.

Epididymis

18

a collection of muscle fibers, vessels, nerves and ducts that run to and from the testes.

Spermatic cord

19

What are the 3 paired structures of the scrotum?

testis, epididymis, and the spermatic cord

20

What are the muscle fibers within scrotum?

dartos and cremaster

21

_____ muscle is a sheet of smooth muscle, situated immediately underneath the skin. It acts to help regulate the temperature of the scrotum, by wrinkling the skin –this decreases surface area, reducing heat loss

dartos muscle

22

Originally, the testes are located on the ________

posterior abdominal wall

23

T/F: As the testes descend through the inguinal canal to the scrotum, they carry their neurovascular supply with them

True

24

During embryonic development they descend down the abdomen, and through the _______ to reach the scrotum.

inguinal canal

25

Arterial supply to the testes and epididymis is via the paired _____ arteries

testicular arteries

26

Lymphatic drainage to the testes is to the ________ nodes

lumbar lymph and preaortic nodes

27

Network of nerves derived from the renal and aortic plexi that innervate the testis

testicular plexus

28

The ______ is a network of veins, responsible for the venous drainage of the testes, acts as a heat exchanger, cooling the arterial blood before it reaches the testes.

pampiniform plexus

29

As it travels through the inguinal canal, the pampiniform plexus condenses into a

single testicular vein

30

The right testicular vein drains into the

inferior vena cava
