corpora cavernosa
26
which muscle pushes blood to maintain and errection
2xischiocavernosa
27

which fascia holds all 3 connective tissue of the penis together
deep (bucks) fascia
31
what is the nickname for the most external fascia
colles
32
where does the suspensory ligament go to and from
erectile bodies to the pubic smyphsis
33
what is the fundiform
the sling that attaches to the pubic symphhysis
34
where were the testes originally located in development
the posterior abdo wall but descends down through the inguinal canal
35
where does sperm travel in the testis
seminiferous tubule, rete teste, epididymis
36
what is the tunica abulginea
it travels into the testicle between the seminiferous tubules
37
what is the tunica vaginalis
it covers the testes
38
where does the vas deferens travel between
the epididymis to the ampulla
39
tell me about the route of the spermatic chord
it starts at the deep ring, passes down to the superifical ring and at that point goes down into the scrotum
40
where is the deep iloinguinal ring sitated
half way between the ASIS and the pubic terbercule
41
where is the superficial ilioinguinal ring situated
next to the pubic terbercule
42
where is the inguinal canal
between the deep and superficial rings
43
where is the seminal vesicle located
between the bladder and the rectum
44
what makes up the ejaculatory duct
the vas deferens and the seminal vesicle duct
45
what do the first fractions of the seminal vesicle produce
spermatozoa and prostatic secretions
46
what is the remaining volume of seminal vesicle secretions made up of
testicular spermatozoa, prostatic secretions and mucus from the bulbourethral glands
47
what things are in the prostatic secretions from the seminal vescicle
alkali fluid fructose prostaglandins clotting factor
48
what does the prostate secrete and why
proteolytic enzymes into the semen to break down the clotting factors so remains a fluid
49
where does the enzymes from the prostate leave the prostate
via prostatic ducts that open into the prostatic part of the urethra immediately before ejaculation

what is contained in the central zone of the prostate and what percentage of the overall prostate is this zone
ejaculatory duct and 25%
51
what is contained in the transitional zone of the prostate and what percentage of the overall prostate is this zone
urethra and 5-10%
52
what is contained in the peripheral zone of the prostate and what percentage of the overall prostate is this zone
65% and is the main body
53
how would you describe the bulbourethral gland
a pea shaped exocrine gland
54
what is the function of the bulbourethral gland
secretes lubricating mucus secretions
55
where is the bulbourethral gland found
in the deep perineal pouch superior to the bulb of penis
56
where does the bulbourethral gland open into
proximal portion of the spongy urethra
57
what are the 3 parts to the male urethra
prostatic, membranous and penile bulbous
58
what muscle covers the spermatic chord

the ureter
61
what is the mnemonic for the layers of the scrotum from superficial to deep
Some Damn Englishman Called It The Testis
62
what are the layers of the scrotum from superficial to deep

testicular, ductus deferens, cremasteric
64
contents of the spermatic chord: 3 veins
genital branch of the genito femoral, cremasteric and autonomic
65
contents of the spermatic chord: 3 other things
