- Name the sections of broad ligament that supports the female repro tract and which part they suspend.
-
Mesovarium - ovary
Mesosalpinx - oviduct
Mesometrium - uterine horns and body of uterus - List and describe layers of female repro tract.
-
Serosa - outer single cell layer of squamous cells which cover the surface of the repro tract.
Muscularis - double layer of smooth muscle, outer layer is longitudinal and inner layer is circular.
submucosa - layer varying thickness that contains blood vessels, nerves and lymphatics.
mucosa - inner layer consisting of secretory epithelial cells, lines the lumen. - List and define the 5 primary ovarian structures.
-
Primary follicles - oocyte w/ single layer of cuboidal epithelium (follicular cells)
Secondary follicles - oocyte w/ 2 or more layers of follicular cells
antral follicles - characterized by fluid filled cavity
corpora lutea - large yellow colored structure , produces progesterone
corpora albicattia - white scar like structure that replaces CL after regression - What are the three cell layers with in the antral follicle and state their function.
-
Theca externa - primarily loose connective tissue; supports the follicle
Theca interna - production of androgens under the influence of leutenizing hormone.
Granulosa cell alyer - have FSH receptors, produce estrogen, inhibin and follicular fluid also thought to govern the maturation of the oocyte. - What is the cervical seal of pregnancy and what purpose does it serve?
- Viscous pluge that cements the folds of the cervix together during pregnancy, thus isolating the developing fetus from the exterior environment and therefor prevents foreign material from entering the uterus.
- List the three types of uteri and state how they are characterized and a mammalian example
-
Duplex - has 2 cervical canals eg. marsupials
Bicornvate - 2 horns, small body eg. cow, ma re, ewe
Simplex - No defined horns ( just a body ) eg. human - Primary functions of the uterus are:
- Sperm transport, luteolysis and control of cyclicity, environment for pre-attachment embryo, maternal contribution to the placenta, and expulsion of the fetus and fetal placenta.
- Gabriello Fallopius is also credited for inventing what and why?
- Condom. He talked about a "linen sheath" in his book on syphillis called Fallico Liber Absoltrismus.
- The cranial vagina has ______________ and ________________ epithelium and the caudal vagina has _______________ epithelium.
- Columnar; ciliated columnar; stratified squamous.
- Most bird have only a right ovary and oviduct that are functional?
- False, LEFT
- The term vagina denta refers to a vagina with teeth?
- True!
- In the female bedbug, the vagina is not the copulatory organ?
- True!
- The vagina of the bitch contaisn a bulb like structure that protrudes cranially into the vestuble, this structure is called the urethral tubercle?
- False, CAUDALLY
- The oviduct consists of three distinct sections, they are the medulla, ampulla and isthmus?
- False, INFUNDIBULUM, not medulla.
- Briefly state some unique characteristics of the female hyena.
- The female hyenas clitoris is so well developed its hard to tell them from a male. She also has a false scrotum. The female is the dominant sex and produces more testosterone than the male.
- Ovary
- Female gonad.
- Infundibulum
- a hollow funnel-shaped portion of the oviduct adjacent to the ovary.
- Fornix vaginae
- The cranial portion of the vagina that forms a crypt that forms as a result of the cervix protruding into the vagina.
- Myometrium
- the smooth muscle layer of the uterus consisting of an inner circular layer and an outer longitudinal layer.
- Endometrium
- mucosal lining (2 specific layers) of the uterus.
- Caruncles
- in ruminants a button, non glandular protrusions like area of the uterine endometrium that will form the maternal side of the catyledonary placenta.
- stratified squamous epithelium
- irregular flattened cells in multiple layers lining portions of the vagina and covering the glans penis.
- corpus hemorrhagicum
- a small blood clot that results from rupture of the blood vessels during ovulation, fills cavity of ruptured follicle.
- Columnar epithelium
- cells taller than wide, resembling columns.
- Clitoris
- small body of highly innervated erectile tissue located in the posterior extremity of the ventral vaginal floor and is the homologue of the penis.
- uterotubal junction
- site where oviduct joins uterus
- zona pellucida
- thick translucent mucoprotein surrounding the oocyte and early embryo.
- cutaneous bridge
- skin external between the anus and dorsal commissure.
- endometrial folds
- folds in endometrium of uteri of sow's mare contributes to maternal placenta.
- Suburethral diverticulum
- outpocketing of tissue located just beneath the urethra that forms a blind pouch.
- Fimbriae
- firnge like structure at the distal end of the infundibulum of the oviduct with probably no functional significance.
- Ovulatory fossa
- specific site on ovary of mare where ovulation occurs.
