Reproductive structures in either sex, male or female, typically include the following basic structures:

Gonads, accessory glands and organs, external genetalia

2

What are gonads?

organs that produce gametes (sperm/egg) and hormones
-testes
-ovaries

3

Structures of the perineum that collectively are known as

external genitalia

4

Each _____ produces sperm and hormones

testis

5

Each ______ is the site of sperm maturation

epididymis

6

Each ____________ (sperm duct) conduct sperm between the testis and prostate gland

ductus (vas) deferens

7

Each _________ secretes fluid that makes up most of the volume of semen

seminal vesicle

8

The _______ secretes fluid and enzymes

prostate gland

9

The ___________ secrete mucus

bulbourethral glands

10

The ______ conducts semen to the exterior

urethra

11

The ____ contains erectile tissue, produces pleasurable sensations during sexual activity, and transports sperm.

penis

12

The _____ surrounds the testes

scrotum

13

The testis is divided into lobules that contain the coiled _______ ______, where sperm production occurs

seminiferous tubules

14

The ________ is a coiled tube through which sperm pass while completing functional maturation. It has a head, body, and tail

epididymis

15

The production of sperm and the endocrine secretion of _________ from the testis is controlled by follicle stimulating hormone (FSH) and luteinizing hormone (LH) produced by the anterior lobe of the pituitary gland

testosterone

16

The production of sperm and the endocrine secretion of testosterone from the testis is controlled by _________ and _____________ produced by the anterior lobe of the pituitary gland

follicle stimulating hormone (FSH)
luteinizing hormone (LH)

17

________ stimulates bone and muscle growth, establishes and maintains secondary sex characteristics, maintains the glands and organs of the male reproductive tract and has effects on libido (sexual drive)

Testosterone

18

Each ________ ascends to enter the abdominal cavity through the superficial inguinal ring. The ductus deferens transports sperm from the epididymis

ductus deferens

19

The _____ includes the ductus deferens and blood vessels, nerves and lymphatic vessels that supply the testis

spermatic cord

20

The ductus deferens enters the abdominal cavity and passes posterior to the urinary bladder to reach the ________

Prostate gland

21

The ________ passes behind the urinary bladder to reach the prostate gland

ductus deferens

22

The ________ also are located posterior to the urinary bladder. They produce roughly 60% of the volume of seminal fluid

seminal vesicles

23

The _________ encircles the proximal portion of the urethra as it leaves the urinary bladder. It produces roughly 30% of the volume of seminal fluid.

Prostate gland

24

The __________ also empty into the urethra. They secrete a thick mucus that helps neutralize acids that remain in the urethra and it also lubricates the tip of the penis

bulbourethral glands

25

_______ includes sperm and the secretions of the structures of the rest of the male reproductive tract

semen

26

The _____ consists of a layer of skin and underlying superficial fascia.

scrotum

27

The left and right _______ cavities are separated by a septum of fascia.

scrotal

28

The _____ functions to conduct urine and semen to the exterior.

penis

29

The _____ surrounds the external urethral orifice

glans

30

The _____ or foreskin is a fold that surrounds the tip of the penis

prepuce

31

What makes up the axial musculature of the urogenital triangle

-ischiocavernosus

-superficial transverse perineal

32

The penis consists of ______ cylindrical columns of well-vascularized erectile tissue.

three

33

The paired _____________are located on the dorsal side of the penis and the ______________ surrounds the urethra.

corpora cavernosa
corpus spongiosum

34

The penis expands at the end to form the ______

glands

35

The 3 phases associated with male sexual response

-Arousal
-Emission
-Ejaculation

36

Arousal is caused by which part of the nervous system

parasympathetic (point)

37

Emission and ejaculation are caused by which parts of the nervous system

sympathetic and somatic (shoot)
