Exam 4 - Female Reproductive System Flashcards
Vulva
External genitalia; vestibule for entry to vagina
Vagina
Site for delivery of sperm, birth canals for delivery and sheath for penis during copulation
Cervix
Powerful smooth muscle sphincter
Uterine body
Site for developing fetus
Oviduct
Site of fertilization
Ovary
Site of Oogenesis and steriodogenesis
Uterine horns
Where fetuses are in litter bearing species
Ovaries are suspended from the body wall by a
reflection of this serous membrane, the ____________
mesovarium
Portion supporting uterine tubes is __________
mesosalpinx
Uterus suspended bilaterally via ____________
Mesometrium
Tunica albuginea
The dense connective tissue capsule around the ovaries
Most vascular part of the ovary (also inner part)
Medulla
_________ of the ovary consists of largely dense, irregular connective tissue interspersed with follicles and contains ____________ cells that have _________ function
Cortex; interstitial; endocrine
Primary follicles
Established prior to birth
Tertiary follicle
Distinguished by a antrum; encased in a tissue developed from theca cells
Follicles contains the ____ and produce _______
Egg; estrogen
Corpus lueteum
Produces progesterone; develops from cells of ovulated follicle
Infundibulum
Thin‐walled, funnel‐shaped structure with a highly complex series of fimbriae at the opening, net-like
Uterus
A body, cervix (neck), and two horns in domestic mammals
__________ on the edges of infundibulum of the oviduct position the infundibulum over the follicle
Fimbriae
Examples of a duplex uterus
Wallaby, rabbit
Examples of a bicornate uterus
Pig, cow, horse
Example of a simplex uterus
Human
Uterine body consists of three layers: ________, ________, ___________
Perimetrium; myometrium; endometrium
Perimetrium
Outside the uterus, covered by the visceral peritoneum
Myometrium
middle muscular layer; grows as the fetus grows, responsive to hormones of the ovaries
The Myometrium smooth muscle wall, _________ tone/relaxes with _________ and _________ tone/contracts with ________
Decreases with progesterone; increase with estrogen
Contraction of this allows expulsion of the fetus
Myometrium
Endometrium
Innermost mucosal layer, highly glandular tissue, varies in thickness and vascularity with hormonal changes
The _________ provides site of attachment for placental membranes
Endometrium
Placenta
Embryo attachment in the uterus is a delayed process,
generally occurring 5-7 days after the embryo reaches the uterus
Animal who has a cotyledonary placenta
Cow
Animal who has a diffuse placenta
Horse
Animal who has a diffuse placenta
Pig
Animal who has a zonary placenta
Dog
Animal who has a discoidal placenta
Primates
Cervix is tightly closed except during ______ and _________
Estrus; parturition
The vagina has glandless ________ _________ epithelium in most species
Stratified squamous
Vestibule
Between vagina and external genitalia, external urethral i common to both urinary and reproductive tracts
Vulva
External genitalia for female, right and left labia, meeting at the ventral and dorsal commissures
Clitoris
Like the penis: consists of two crura, or roots, a body, and a glans; only the glans is visible externall
Blood supply to vagina
Very branched, with all named vessels being bilateral
_______ artery arises from the aorta caudal via the renal arteries
Ovarian
Primary blood supply to the uterine body and horns is the ________ artery that is derived from the ______ artery
Uterine; vaginal
_______ artery is the primary blood supply to the _______ in the region of the developing fetus
Uterine; uterus
