Female
Genital Tract
Ovary — source of ova & hormones (estrogen and
during a
pregnancy progesterone
(CL))
Uterine tube:
( Oviduct; “Fallopian tube” )
- Exits laterally from uterine horn (extends
cranially, arcs
ventrally, runs caudally, hooks
dorsomedially)
-
Terminates medial
to ovary in a funnel-shaped infundibulum
that
has fimbriae (villi)
Uterus:
1. Cervix —
short, thick muscular wall & narrow canal
2. Body
— relatively short in carnivores
3. Uterine horns — paired, relatively
long
Vagina:
- extends from the vestibule to a fornix at
the level of the cervix
- displays longitudinal folds when not
expanded
Vestibule:
- extends from vulval cleft to the transverse
fold (hymen) that
marks the vestibulo-vaginal junction
- receives the external urethral opening, on
a tubercle (dog) or in
a slit (cat)
- constrictor vestibuli m. (striated) is in the wall of the vestibule
- the wall contains vestibular glands
(mucous) — a major
vestibular gland in the cat
-
in the dog, the
wall contains an accumulation of erectile tissue = vestibular bulb
Clitoris: homologue of the penis
- located deep (cranial) to the fossa of the
clitoris
- composed of: glans = erectile tissue
body = fat in a connective tissue capsule
crus = scant erectile tissue enclosed in
fibrous c.t.(
right & left crura)
Vulva:
- is
composed of left & right labia which bound a vulval cleft
- constrictor
vulvae m. (striated) is in the wall of each labium
- an
indentation, the fossa of the clitoris, is present ventrally
Ligaments associated with the female genital tract:
1)
suspensory ligament of the ovary — extends from ovary to
dorsal body wall
2) proper
ligament of the ovary — extends
between ovary &
cranial end of uterine horn
3) round
ligament of the uterus — extends from
cranial end of
uterine
horn thru inguinal canal
4) broad
ligament (lateral ligament of
uterus), which has the
following subdivisions:
a) mesometrium; b) mesovarium; c) mesosalpinx
