Side ASide B
What is the head of the penis called?
glans
The long and smooth portion of the penis is called the
shaft or body
The foreskin (skin that covers the penis when it is not erect) of the penis is called
prepuce (male equivalent of female clitoral hood/prepuce)
The sac of skin and muscle that holds the male testis is called
scrotum (male equivalent of female labia majora)
What structure divides the testes?
raphe
Erectile tissue of the penis that runs along the inferior portion of the shaft of penis (bulb...
corpus spongiosum
Where is the corpus spongiosum located?
surrounding urethra
What helps to prevent the urethra from closing during an erection (to allow for sperm flow)?
corpus spongiosum
Twin pair of erectile tissue that run along the superior portion of the shaft of the penis
corpora cavernosa
What tissue is responsible for the male erection?
corpora cavernosa
In females, corpora cavernosa comprises the
clitoris
Male primary sex organ is the
testes (male equivalent of female ovaries)
The system of small veins that run alongside the ductus deferens to cool the blood flowing...
pampiniform plexus
The temp required by the sperm to develop is:
1 degree cooler than the body tem (97.6°F)
A muscle that covers the testes
cremaster muscle
What is the function of the cremaster muscle?
to raise and lower the testes for thermal regulation
A bluish-white fibrous sac covering just superficial to the testes is called the
tunica albuginea
A serous membrane that covers the tunica albuginea is called
tunica vaginalis
The tunica vaginalis is filled with
serous fluid
The site of sperm maturation is called the
epididymis
What does the epididymis connect?
the efferent ductules from the posterior testes to the vas deferens (ductus deferens)
Where are sperm formed?
in the testes in ther seminiferous tubules
Where do the sperm mature?
in the epididymis
How are the sperm carried to the urethra from the epididymis?
ductus (or vas) deferens
Life cycle of sperm:
spermatogonia (primordial cells), spermatocytes, spermatids, sperm
Where are interstitial cells (Leydig cells) located?
between seminiferous tubules
What secretes fluid to lubricate the urinary canal and raise the pH to an alkaline level?
bulbourethral gland
What secretes fluid that contains enzymes to help with pH and to help break down fluids in...
prostate gland
Please list the pathway of spern ejection.
(testes) seminiferous tubules ---> epididymis ---> ductus (vas) deferens ---> addition...
Designate the difference between sperm and semen.
semen = all fluid + sperm (bulbourethral fluid, seminal vesicle fluid, prostate fluid)
