Also known as the Semenal Vessel, it stores
spermatozoa in preparation for ejaculation into the
Urethra.
The external opening of the
digestive
tract for expelling solid waste.
Membraneous sack that serves as the recepticle
for
urine. A valve at its base restricts semen from being
`backwashed' into it.
The hollow muscular organ in the female in
which the
fertilzed ovum normally becomes embedded and in which
the developing embryo and fetus is nourished. It is
supported by direct attachment to the Vagina and by
indirect attachment to various other nearby pelvic
structures.
The enlarged proximal part of the Corpus
Spongiosum
found between the two crura of the penis. The crura
are a continuation of each Corpus Cavernosum,
diverging posteriorly (at the back) to be attached to
the pubic arch. Muscles here help to drive urine or
semen down and out of the Urethra. These muscles are
responsible for the "flagging" of a stallion's tail
during ejaculation.
The neck or constricted part of the Uterus
connecting
to the Vagina. In periods of Heat it is relaxed and
open, otherwise it is tightly closed. During pregnancy
it seals itself with a mucus "plug" that is removed
shortly before delivery of the foal.
The canal or hollow depression containing the clitorus.
When the mare "winks" the clitorus is briefly projected
out of the vulva beyond the vaginal opening.
A small thumb-like structure situated in the base of
the vulva. It is the female equivalent to the male
glans and it's role in females is purely that of stimulation.
When the mare "winks" the clitorus is briefly projected
out of the vulva beyond the vaginal opening.
A column of erectile tissue that forms the
urethral
surface of the penis, and in which the urethra is
found; its distal expansion forms the glans penis.
Elongated cord-like structure along the
posterior
border of the Testis, whose elongated coiled duct
provides for storage, transit, and maturation of
spermatozoa and is continuous with the Ductus (Vas)
Deferens. It is often seen as a "lump" on top or
behind the Testis.
Membraneous and semi-muscular opening which
conveys
urine or semen to the exterior of the body.
A long slender tube that extends from the upper
lateral horn of the Uterus to the region of the Ovary.
The cap-shaped expansion of the Corpus
Spongiosum at
the end of the penis, or "head", where the Urethra
exits. When sufficiently sexually exited, this area
becomes engorged with blood expanding the Glans into a
flared or bell shape up to ten times its normal
surface volume. This helps to prevent ejaculated semen
from exiting the Vagina during copulation and is
thought to help stimulate the mare's reproductive
system into being more receptive.
A covering fold of skin that protects the penis.
A fibrous and semi-muscular gland that produces
fluid
that neutralizes urine, lubricates the urethra and
contributes to the liquefaction of coagulated semen.
Also known as the Gracillus muscle, allows the
penis
to be voluntarily extended and retracted from the
Prepuse/sheath.
A narrow tube extending from the body of the
Uterus to
the Fallopian Tube in which the ova travel on their
way to the Uterus.
Excretes urine and regulates the balance of
electrolytes in the bloodstream.
One of the two sexual organs in the female
which the
ova, or eggs, are formed.
Either of the paired egg-shaped glands normally
situation in the scrotum; each contains the
seminiferous tubules, wherein the spermatozoa are
produced. Specialized interstitial cells (Leydig
cells) secrete Testosterone.
The pouch or sack of skin that contains the
Testis and
their accessory organs. The skin can contract or
expand to regulate the temperature of the Testis in
order to efficiently produce spermatozoa.
Also known as the Vas Deferens, a fibromuscular
tube which conveys spermatozoa from the Epididymis to the
Ampulla of Vas Deferens/Semenal Vessel.
Fibromuscular tube that conveys urine from the
Kidney
to the Bladder.
Membraneous and semi-muscular canal which
conveys
urine or semen to the exterior of the body.
The canal in the female, extending from the
Vulva to
the Cervix, which receives the penis in copulation.
Produces a nourishment-rich mixture for
spermatozoa
and is expelled at the moment of ejaculation into the
Urethra.
The space or cavity at the entrance to the
vaginal
canal.
The region of the external genital organs of
the
female, including the clitorus, vestibule of the
vagina, greater and lesser vestibular glands, and
vaginal orifice.
