30
Sertoli cells tissue
Tall columnar irregular epithelia)
31
sertoli cells inside structure
Ovoid or triangular euchromatic nuclear, prominent nucleolus, abundant ser some rer, developed Golgi complexes, numerous mitochondria, lysosomes
32
Sertoli cells function
Nourish thespermanogenic cells, divide the seminiferous tubules into two compartments& give metabolic & physical support to spermanogenic linage
33
Junctions between sertoli cells
Tight occluding & gap
34
Where are tight junctions found
BasOlateral membranes
35
What's the tightest blood tissue barrier in mammals
Sertoli tight junction
36
Gap junction function
help regulate the transient changes in the occluding junctions and synchronize activities in the spermatogenic cells.
37
spermatocytes, spermatids, and developing sperm are connected to plasma proteins and nutrients
false, they’re isolated by the blood-testis barrier.
38
What does sertoli cells secret
Androgen binding protein, inhibit B & mallerian inhibiting substances
39
Androgen bindingprotein funaction
ConcentraTe testosterone to a level required for spermiogensis
40
Inhibin B effect
Feed back to anterior pituitary gland & suppress fsh synthesis and release
41
Mallerian inhibiting substances is found in
Male embryo
42
Name the intrAtesticular ducts
The straight tubules, the rete testis & efferent ducbules
43
Straight tubules lining
Simple cuboidal epithelium
44
When does sertoli cells begin to disappear
Beginning of straight tubules
45
Where is the rate testis found

46
How many efferent ductless
20
47
Efferent ductless lining
Non ciliated cubodial & taller columnar cilliated
48
Scalloped appearance
Efferen-ductules
49
How does the efferent ductless aid in sperm movement
1 -a thin layer of circular oriented smooth muscles 2- ciliary activity
50
Name the excretory ducts
Epididymis, ductus deferent & urethra
51
Epididymis tissue
Pseudostratified columnar epithelium
52
Columnar principle cells
Epididymis
53
Characterstic of epididymis
Long stereocilia cells, small round stem cells & basal cells
54
Principle cells role in the epididymis
Remove water & residual bodies entering the epididymis& secrete various products

56
Ductus deferent lining
Pseudostratified columnar
57
Ductus deferens muscular

65
Where does ducts from individual glands empty
Prostatic urethra
66
Major zones of prostate
Peripheral, central & transition
67
Peripheral zone of prostate gland
70% of the organ’s tissue, contains the prostate’s main glands with the longest ducts into the prostatic urethra.
68
Central zone of prostate gland
25% of the gland’s tissue and contains the periurethral submucosal glands with somewhat shorter ducts.
69
Transition zone of prostate gland
5% of the prostate volume, contains the periurethral mucosal glands, and like the central zone surrounds only the superior portion of the urethr

primarily deposited glycoproteins and keratan sulfate
72
corpora amylacea _____ with age
Increase
73
Seminal vesicles secretion include
Fructose, prostaglandin & fibrinogen
74
What does elevated levels of circulating psa indicate

Where does bulboureohral glands empty
Penile ureohra
76
Bulbourethral glands lining
Simple columnar epithelium
77
Bulbourethral gland is_____ dependent
Testosterone
78
Bulbouretbra) funaction
During erection, the bulbourethral glands, as well as numerous, very small, and histologically similar urethral glands along the penile urethra, release a clear alkaline mucus-like secretion, which coats and lubricates the urethra in preparation for the imminent passage of sperm.
79
Penis cylindrical masses
Two corpora cavernous (dorsal) & one corpora spongiosum (ventral)
80
Penile urethra lining

Nutritive arterioles & small coiling helicine arteries
82
Hydrocele
An excessive accumulation of serous fluid in one or both sides of the scrotal sac, termed a hydrocele, is the most common cause of scrotal swelling and a condition easily corrected surgically.
83

The failure of one or both testes to descend from the abdomen, occurs in about 4% of male neonates
84
Common features of poor semen
oligospermia (ejaculate volume >2 mL), sperm cell density less than 10-20 million/mL, abnormal sperm morphology, and flagellar defects that impair sperm motility.
