corona:
The 'crown,' a ridge of
flesh demarcating where the head of the penis and the shaft
join.
corpa cavernosa: The corpora cavernosa are the two
spongy bodies of erectile tissue on either side of the penis
which become engorged with blood from arteries in the penis,
thus causing erection.
cowper's
glands: The Cowper's glands secrete a small amount ofpre-ejaculate
fluid prior to orgasm. This fluid neutralizes the acidity
within the urethra itself.
ejaculatory
ducts: The path through the seminal glands which semen
travels during ejaculation.
epididymis:
The epididymis is a 'holding pen' where sperm produced by
the seminiferous tubules mature. The sperm wait here until
ejaculation or nocturnal emission.
foreskin,
prepuce: A roll of skin
which covers the head of the penis in uncircumcised men.
frenulum,
frenum: A thin strip of flesh on the underside of the
penis that connects the shaft to the head.
glans:
The glans is clearly visible in illustration (A) as the head
of the penis. The glans in uncircumcised men is usually
covered by the prepuce. The glans is highly sensitive, as is
the corona, the ridge of flesh that connects the glans to the
shaft of the penis.
prostate gland: Also produces a fluid that makes up the
semen. The prostate gland also squeezes shut the urethral duct
to the bladder, thus preventing urine from mixing with the
semen and disturbing the pH balance required by sperm.
scrotum:
The scrotum is a sac that hangs behind and below the penis,
and contains the testes, the male sexual glands. The scrotum's
primary function is to maintain the testes at approximately 34
C, the temperature at which the testes most effectively
produce sperm.
seminal
vesicles: The seminal vesicles produce semen, a fluid that
activates and protects the sperm after it has left the penis
during ejaculation
smemga:
A substance with the texture of cheese secreted by glands on
each side of the frenulum in uncircumcised men.
testes, testicles: The male sexual glands, the two
testes within the scrotum produce sperm and testosterone.
Within each testis is a kilometer of ducts called the
seminiferous tubules, the organs which generate sperm. Each
testicle produces nearly 150 million sperm every 24 hours.
urethra, meatus: The opening at the tip of the penis to
allow the passage of both urine and semen.
vas
deferens: The ducts leading from the epididymis to the
seminal vesicles. These are the ducts that are cut during the
procedure known as vasectomy. |
