THE TESTIS WILL DEGENERATE. THE SIZEOF IT WILL DECREASE. THE LEYDIG CELL WILL SEIZED FUNCTIONING.

Question 6

WHAT IS THE EFFECT OF THE REMOVAL OF TESTES ON AN INDIVIDUAL.

Answer 6

ANDROGEN LEVELS WILL BE VERY LOW.

Question 7

NEGATIVE FEEDBACK MECHANISM

Question 8

EPIDIDYMIS

Answer 8

convoluted tubule, receives spermatozoa and stores them as they mature

Question 9

DUCTUS (VAS) DEFERENS

Answer 9

muscular (smooth muscle) tube about 40 to 45 cm long, conveys sperm from epididymis to the ejaculatory duct

Question 10

SEMINAL VESICLES

Answer 10

paired tubular glands, posterior to the prostate, about 15 cm long, produce seminal fluid, join the ductus deferens at the ejaculatory duct

Question 11

PROSTATE GLAND

Answer 11

walnut-sized gland, surrounds the urethra as it leaves the urinary bladder, produces prostatic fluid that is added to semen

Question 12

URETHRA

Answer 12

canal that passes through the prostate gland, enters the penis, and conveys the semen for expulsion from the body during ejaculation

Question 13

TESTES (CHARACTERISTIC)

Answer 13

Develop in retroperitoneal abdominal wall and descend into scrotum

Question 14

EPIDIDYMIS (CHARACTERISTIC)

Answer 14

Consist of head, body and tail; functions in maturation and storage of sperm

Question 15

DUCTUS (VAS) DEFERENS (CHARACTERISTICS)

Answer 15

Passes in spermatic cord through inguinal canal to join duct of seminal vesicle (ejaculatory duct)

Question 16

SEMINAL VESICLES

Answer 16

Secrete alkaline seminal fluid

Question 17

PROSTATE GLAND (CHARACTERISTIC)

Answer 17

Surrounds prostatic urethra and secretes prostatic fluid

Question 18

What does hypothalamus hormone produce?

Answer 18

GnRH

Question 19

What does GnRH stands for?

Answer 19

Gonadotropin-releasing hormone

Question 20

What is the two secretion of GnRH?

Answer 20

Follicle-stimulating hormone (FSH)
Luteinizing hormone (LH)

Question 21

What does LH stimulates to secrete TESTOSTERONE?

Answer 21

Leydig cells

Question 22

What is required for spermatogenesis?

Answer 22

testosterone

Question 23

Testicular estrogen

Answer 23

derived by aromatization of testosterone in many testicular cells, could also play an important role in spermatogenesis

Question 24

stem cells that line the basal (outer) layer of the seminiferous tubule germinal epithelium and undergo mitotic division to produce primary spermatocytes

Answer 24

Spermatogonia

Question 25

large germ cells that possess 46 chromosomes and undergo meiosis to produce secondary spermatocytes

Answer 25

Primary spermatocytes:

Question 26

these cells are smaller than primary spermatocytes and undergo a second meiotic division very quickly to produce spermatids

Answer 26

Secondary spermatocytes:

Question 27

• these cells undergo a maturation process (spermiogenesis) • form a head and tail and become spermatozoa • pass from the lumen of the seminiferous tubules to the epididymis for storage and maturation

Answer 27

Spermatids:

Question 28

THESE CELLS UNDERGO A MATURATION PROCESS CALLED SPERMIOGENESIS. • A. Spermatogonia • B. Primary spermatocyte • C. Secondary spermatocyte • D. Spermatids • E. Spermatozoa

Answer 28

D. Spermatids

Question 29

about 20 cm long and descriptively is divided into three parts:

Answer 29

Urethra

Question 30

proximal portion of the male urethra that runs through the prostate gland

Answer 30

Prostatic urethra:

Question 31

short, middle portion that is enveloped by the external urethral sphincter

Answer 31

Membranous urethra:

Question 32

courses through the bulb of the penis, the pendulous portion of the penis and the glans penis to open at the external urethral orific

Answer 32

Spongy urethra:

Question 33

reside in the external urethral sphincter pea-sized glands secrete a clear, viscous alkaline mucus lubricate the lumen of the spongy urethra and neutralize its acidic environment, thus preparing the way for the semen

Answer 33

bulbo-urethral (Cowper’s) glands

Question 34

• prostatic urethra • sympathetic control • closes off the urethra during ejaculation so that semen cannot pass into the bladder and urine into the urethra

Answer 34

internal urethral sphincter

Question 35

membranous urethra • skeletal muscle • innervated by branches of the pudendal nerve • voluntary control

Answer 35

external urethral sphincter

Question 36

What is spermatosis?

Question 37

What do you think is the disadvantage of spermatosis?

Question 38

Spermatozoa

Answer 38

Sperm Cells

Question 39

Testis to epidedymis what will happen to immature sperm

Answer 39

Beforw the sperm cell is release theres a modification happening. Theres an acid that prevents the immature release of the acrusome

Question 40

The lipid coating is removed so that the granules inside the sperm cell is able to reach the nucleus of the egg cell

Answer 40

Capacitation

Question 41

Retrograde ejaculation

Answer 41

The semen goes to the urinary bladder. Ummakyat instead of bejng ejaculated

Question 42

How do you check a retrograde ejaculation

Answer 42

If after sex the urine is hazy. The semen must have mixed in the urine

Question 43

Internal urethral sphincter

Answer 43

It involuntary closes the urine pathway so that it doesnt get diaclosed during semen ejaculation

Question 44

External urethral sphincter

Answer 44

You can control it. Kaya kaya umihi when on purposely wanted to
