16
Q

what is the architecture of the flagellum

A

micortubular axoneme (as in cilia)

17
Q

Leydig cells are stimulated by what hormone

A

LH

18
Q

lining of the straight tubule

A

mix of (microvillus) simple cuboidal ans sertoli

19
Q

efferent ductules merge to form the epididymus. what are the cell types of the efferent ductules

A

simple cuboidal (reabsorbs 90 % of the testicular fluid), ciliated columnar (create current)

20
Q

three important functions of the epididymus

A

STORAGE (12 ft long), transport (smooth muscle), maturation (secretions)

21
Q

cell types of the epididymus AND vas deferens

A

pseudostratified columnar with stereocilia. epididymus: BASAL and PRINCIPAL cells

22
Q

most defining feature of the vas deferens

A

three smooth muscle layers (long., cir., long.) necessary for ejaculation

23
Q

beginning and ending structure of the vas deferens

A

the ductus epididymus, the ampulla

24
Q

what is the purpose of the seminal vesicle

A

to make the 70% of ejaculate composed of yellow fructose-rich fluid

25
Q

cell types of the seminal vesicle

A

pseudostratifed columnar with microvilli and a SINGLE FLAGELLUM

26
Q

structure of the prostate gland

A

3 layers of alveolar glands that have separate ducts to the urethra

27
Q

the 3 layers of prostate glands starting from the periphery

A

main (largest), submucosal, mucosal

28
Q

prostatic concretions

A

concentric figures on the lumen made from calcified glycoproteins

29
Q

purpose of the bulbourethral gland (Cowper’s)

A

produces lubricating mucous prior to ejaculation

30
Q

lining of the bulbourethral gland

A

simple cuboidal to columnar

31
Q

muscle layer of the bulbourethral gland

A

both types

32
Q

how are the corpora cavernosa different from the corpus spogiosum

A

they have an incomplete median septum and a VERY thick fibroelastic tunica albuginea

33
Q

erectile tissue definition

A

large endothelium-lined spaces separated by CT trabeculae and smooth muscle

34
Q

vasculature of the penis

A

deep and dorsal arteries and deep dorsal vein

35
Q

what initiates the erection

A

parasympathetic stimulation-> contraction of smooth muscles of the AV shunt -> NO release to dilate helicine arteries

36
Q

what initiates ejaculation

A

sympathetic stimulation > contraction of gland sm mus -> sphyncter of bladder contracts ->bulbospongiosus mus. spasm at the corpus spongiosum

37
Q

what initiates detumescence

A

stop of parasym stimulation-> AV shunt opens
