الجهاز التناسلي األنثوي هو الجهاز المسؤل عن االخصاب والحمل والوالدة في
اإلناث يتكون من مبيض أيمن ومبيض أيسر( يكون األيمن أكثر نشاطا في االبقار
واأليسر أكثر نشاطا في الخيول) المسؤلة عن إنتاج البويضات و الهرمونات
الجنسية (االستروجين و
البروجسترون).
قناة البيض المسؤلة عن نقل البويضة من المبيض الى الرحم ونقل النطف من قرن
الرحم الى المنطقة الوسطى من قناة البيض حيث يحدث االخصاب وتتكون من
ثالثة أجزاء(القمع قرب المبيض والحويصلة
والبرزخ).
الرحم وهو الجزء المسئول عن تغذية الجنين والحمل والوالدة وإنتاج وإفراز
هرمون ) )PGF2άالبروستوكالندين ويتكون من جسم الرحم والقرنين والعنق
وشكله يختلف من نوع حيوان ألخر(أفراس ,أبقار ,نعاج ,كالب ,قطط ,خنازير) .
Anatomy and physiology of
femalegenitalia
the female G.S consist of
1- ovaries.
2-oviduct.
3- uterus.
4- vagina.
5- vestibule.
6- vulva.
Ovaries:
the ovaries perform exocrine oogenesis
and endocrine function steroidogenesis
in female, the ovaries varies in size
&shape according to spp. , estrous
cycle,age of female, breed and presence
or absence of pathological condition,
the structural &functional unit of the
ovary is the follicle
Internal structure and function
In most domestic animals the ovaries
consist of a peripheral parenchymatous
zone(cortex) containing various stage of
follicular and luteal gland development
surrounding a central vascular zone
(medulla)
comprising
collagenous
connective tissue rich in blood vessels.
*What's the main function of ovary
Uterine tube(oviduct)
They are tubular ,tortuous structure situated
bw ovary and tip of uterine horn (utro-tubal
junction ).The oviduct derived from
mesonephric duct.The length of oviduct in
mare &cow 20-30 cm ,in ewes & doe 15-20
cm ,in sow 15-30cm
Why cannot palpated oviduct in
rectal palpation ?
.
The oviduct consist of 3parts joint together ,
the 1stinfundibulum adjacent the ovary , its
free end &it's usually have fimbria to pick up
ova ,the 2nd part is the larger part called
ampulla , site of fertilization especially in
ampulla isthmus junction ,3rd part is
shorter& narrow part called isthmus ,the
junction bw isthmus and tip of uterine horn
called utro-tubal junction or ostium uterine
tube
*What's the main function of oviduct
Uterus
Bovine Uterus
*Bicornuate uterus with relatively long uterine
horn .
*coiled in shape like ram horn.
*the length of uterine horn in cow (20-25cm)
*the length of uterine body (4.5-5 cm).
. the endometrium have special structure called
carancles
What deferent between bov .uter &mare
uter?
Mare uterus
Like T shape
There are no carancles in mares.
the endometrial surface is composed of
longitudinal folds
Ovine uterus
Like in bevies but small in size and little in
number of carancles
Canine uterus
Yin shape , Bipartate, Length of body 10-12
cm ,length of horn 12-15 cm situated in
abdominal cavity .
Swine uterus
Intestinal in shape ,length of body 5 cm length of horn
40-100 cm
Cervix
In all cases the caudal portion consist of
cervical a thick walled segment with a
narrow lumen that act as
sphincterregulating the flow of maternal to
from the uterus.Situated bw the uterus
&posterior part of vagina which called the
vaginal part of uterus or portiovaginalis of
the cervix.
Bovine cervix
8-10 length ,2-4 cm in diameter , the cervix
in bovine consider the guide to the female
gentilia by rectal palpation , because
presence of cervical rings 3-5 rings , it has
cartilaginous in consistency but there is no
cartilage, the cervix have longitudinal fold
interrupted by circular mucosal folds.
Mare (equine) cervix
5-7.5 cm length , 2.5-5 cm diameter have
longitudinal folds .
Ovine cervix
Similar to bovine but small , 4-6 cm in
length , 2-3 cm in diameter, 5-7 cervical
rings (anullar rings).
Canine cervix
0.5-5 cm in length , 0.5-0.75 cm in diameter
has longitudinal folds
Swine cervix
It has spiral lumen to fit the boars penis
The vagina
It make up a major portion of anatomic
connection bw the uterus & external
environment .
Extend from fornix to the external urethral
orifice & hymen
Vestibules
Extend from vulval cleft to the hymen ,that
make up the vestibule-vaginal junction
&urethral orifice.It resample the terminal
part of genital tract and belonging to both
the urinary and genital sys
The vestibule have minor &major glands
The vulva is just caudal to the vestibule
&consist of two labia and clitoris.
