Anatomy and physiology of femalegenitaliathe 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 functionIn 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 shapeThere are no carancles in mares.the endometrial surface is composed
of longitudinal folds
Canine uterus
Yin shape , Bipartate, Length of body 10-12 cm ,length of horn 12-15 cm situated in abdominal cavity .
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.
Ovine cervix
Similar to bovine but small , 4-6 cm in length , 2-3 cm in diameter, 5-7 cervical rings (anullar rings).
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.
