seminiferous tubules
|
|
spermatozoa =
|
sperm
|
|
sperm pass from seminiferous tubules into this and then into the efferent ductules to complete the maturation process before leaving the testes
|
rete testis

2 scrotal wall muscles
|
dartos and cremaster
|
|
dartos muscle is part of what wall?
|
scrotal wall

|
cremaster muscle is attached to the...
|
spermatic cord
|
|
where are sperm stored before ejaculated?
|
epididymis
|
|
very coiled tube that fits snugly over the upper end of each testis. Sperm from the efferent ductules are stored in the epididymis before it is ejaculated. The total length of this structure is 6 to 7 meters.
|
epididymis
|
|
The separation between the two testes.
|
median septum
|
|
sperm network of canals
|
rete testis
|
|
The area that the rete testis empties into.
|
efferent ductules
|
|
vas deferens =
|
ductus deferens
|
|
a continuation of the epididymis that ascends to the urethra. It passes out of the scrotum and into the abdominal cavity through an inguinal canal. It is part of the spermatic cord that also includes blood vessels, nerves, and a lining, which all function closely with the testis.
|
vas deferens

seminal vesicles, prostate gland, and bulbourethral glands are call the ......glands
|
accessory
|
|
accessory gland secretions and sperm together is called...
|
semen
|
|
glands that are found immediately beneath the bladder; secrete a sticky, alkaline yellow substance that assists in sperm movement and longevity; union of the seminal vesicles and the vas deferens that make up the ejaculatory ducts
|
seminal vesicles
|
|
union of seminal vesicles and vas deferens make up which ducts
|
ejaculatory ducts
|
|
surround urethra at base of bladder; singular gland made up of many small glands and muscle fivers enclosed in a dense connective tissue; secretes a thin, milky substance that assists in sperm motility and is also alkaline. (The alkaline nature of the seminal fluid protects the sperm from the acidic environment of the female vagina.)
|
prostate gland
|
|
pea size glands, located inferior to prostate
|
bulbourethral glands

bulbourethral glands =

Cowper glands

|
an approximately 20 cm long S-shaped tube that connects the urinary bladder and ejaculatory ducts to the outside of the body.

ejaculation
|
|
In response to stimulation of nerves and vasoconstriction of the veins, there is an increase in blood supply which causes an...
|
erection
|
|

After ejaculation is complete, the blood vessels return to their normal caliber, draining excess blood from the penis and returning it to what kind of ?state
|
flaccid state
|
|
A continuation of the epididymis that goes up and into the urethra.
|
vas deferens
|
|
A group of structures that go through the inguinal canal to the testis. The structures include the vas deferens, arteries, veins, lymphatic vessels, and nerves.
|
spermatic cord
|
|
The combination of secretions from the seminal vesicles, prostate gland, and bulbourethral glands with sperm.
|
