Answer 11

sustentacular cells

Question 12

what is the interstitial endocrinocytes?

Answer 12

it is located between the coils of the semineferous tubules they are cells that secrete hormones into the blood

Question 13

Answer 13

they are a set of tubes that take sperm from the teste to the outside world

Question 14

what are the ducts in the teste?

Answer 14

testicular ducts

Question 15

what takes sperm out of semineferous tubules and leads to the rete testis?

Answer 15

the straight tubules

Answer 20

it is the most inferior portion and it joins the ductus deferens

Question 21

what is the efferent ducts?

Answer 21

it leads from the rete testis to the ductus epididymis

Answer 22

the ductus epididymis

Question 23

what leads from the tail of the epididymis exits out of the scrotum (in spermatic cord) and enters body cavity through lower abdominal muscles and back into pelvic cavity, over top of bladder, ends at inferior posterior of bladder then joins the ejaculatory duct?

Answer 23

the ductus deferens

Question 24

what is the ejaculatory duct?

Answer 24

it is a short tube that joins the urethra in the prostate gland

Question 25

what leads from the ejaculatory duct to the outside world? it has 3 parts.

Answer 25

the urethra

Question 26

what is the prostatic urethra?

Answer 26

it is the first part of the urethra through the prostate gland

Question 27

Answer 27

membranous urethra

Question 28

what is the penile (spongy) urethra?

Answer 28

runs through section of penis called corpus spongiosum, ends at external urethral orifice

Question 29

what are the seminal vesicles?

Answer 29

two glands on posterior/inferior of bladder. they empty fluid into ejaculatory duct, fluid allows sperm to swim, it contains alkaline chemicals, enzymes, and fructose(food)

Question 30

what is a donut shaped gland around the urethra, inferior to bladder, adds more fluid to the semen, citric acid(food), and more enzymes?

Answer 30

prostate gland

Question 31

what is the bulbourethral gland?

Answer 31

at the root of the penis (inside), puts an alkaline liquid into the urethra before the sperm arrives (neutalizes acid in penis so sperm dont burn and die)

Answer 32

penis

Question 33

what are the bands of connective tissue to hold the penis in place?

Answer 33

ligaments of the penis (2)

Question 34

what is continuous with the fascia of the penis and supports weight of the penis?

Answer 34

fundiform ligament

Question 35

what is the suspensory ligament?

Answer 35

helps support penis like fundiform ligament

Question 36

what is the body(shaft) of the penis?

Answer 36

most of the mass of the penis above the skin. wrapped in smooth muscle, connective tissue, and skin. made of 3 cylinders of erectile tissue.

Question 37

what is the corpus spongiosum of the body of the penis?

Answer 37

it is the inferior mass of erectile tissue contains the urethra.

Question 38

what is the 2 superior masses of erectile tissue ?

Answer 38

corpora cavernosa

Question 39

what is the root of the penis?

Answer 39

it is the part that is deep in the body
