What is the primary female sex organ?
Which type of follicle has an antrum?
What type of uterus is present in a cow?
What is the corpus albicans?
a white, scar, like structure that forms on the ovary after a corpus luteum degenerates.
What is the inner most layer of cells in a tertiary follicle?
What is the main function of the uterus?
- muscle contractions for transport of sperm and expulsion of fetus/placenta
- absorption and phagocytosis of cells
- site of sperm capacitation to prep for fertilization
- provide environment for embryonic/fetal growth
- produce hormones
What is the main function of the cervix?
- transport, barrier, and reservoir for sperm
- block bacterial invasion of uterus
- birth canal
What is the main function of the vagina?
- copulatory organ
- secretes lubrication
- birth canal
- secretes pheromones
What is the significance of the germinal epithelium of the human ovary?
site of ~85% of ovarian cancers
In the chicken, which follicle will ovulate in 2 days?
the 2nd largest tertiary follicle
Which of the oolong animals is easiest to artificially inseminate: Cow, mare, ewe, or pig?
In which species foes ovulation occurs at only one place on the surface of the ovary?
To which part of the uterus does the endometrium belong?
mucosa and submucosa
What is the main function of the infundibulum?
to capture the ovulated oocyte
What is the fornix of the vagina?
a pocket-like area where he anterior vagina connects to the cervix, it's the site of semen deposition in some species
When are the cell types of the epithelium of the vaginal mucosa?
posterior: stratifies squamous
Name all parts of the female reproductive tract.
vulva, labia, clitoris, vagina, cervix, uterine body, uterine horns, oviduct, ovary
Define primordial follicle.
oocyte surrounded by a layer of flattened pre-granulosa cells
Define primary follicle.
oocyte surrounded by a single layer of cuboidal granulosa cells
Define a secondary follicle.
oocyte surrounded by more than one layer of cubical granulose cells
Define a tertiary follicle.
oocyte surrounded by multiple layers of granulose cells and theca cells, presence of an atrium, highly vascularized, only follicle capable of ovulation
What re the cell layers of a tertiary follicle.
granulosa, theca interna, theca externa
Name all the parts of the oviduct.
infundibulum, ampulla, ampullary-isthmus junction, isthmus, utero-tubal junction
What are the 3 layers of the uterus?
endometrium, myometrium, perimetrium
Describe the broad ligament.
connective tissue sheet which supports and suspends the reproductive tract
Describe the mesometrium.
portion of the broad ligament that connects and supports he uterus
Describe the mesovarium.
portion of the broad ligament that connects to and supports the ovaries
Describe the mesosaplinx.
portion of the broad ligament that connects to and supports the oviducts
What are the layers of a tubular reproductive organ?
mucosa, sub mucosa, circular smooth muscle, longitudinal smith muscle, serosa
What is the difference between the ovaries of a ruminant and a mare?
Ruminant ovaries feature he cortex on the outside and medulla on the inside and ovulation can occur anywhere on the ovary.
In mares, the optical and medullary layers of the ovary are inverted and normal ovulation can only occur at the ovulation fossa
What are the three types of uteri?
Duplex; bicornuate; simplex
Describe a duplex uterus according to the species.
2 uterine horns; 2 cervices, 1 (rabbit, mouse) or 2 (opossum) vaginas
Describe a bicornuate uterus according to the species.
1 vagina, 1 cervix, 1 uterine body, 2 uterine horns (ewe, cow, sow, mare bitch, queen)
Describe a simplex uterus according to the species.
1 vagin, 1 cervix, 1 large uterine body, no uterine horns (women)
Describe a bovine cervix.
composed of thick connective tissues and has 4-5 annular rings which must be maneuvered through during the AI process. Mucus is secreted near the time of breeding and ovulation.
Describe a mare's cervix.
cervix has longitudinal folds that makes AI easy
Describe a sow's cervix.
has this interdigitating pads which makes AI difficult and there is no vaginal fornix.
What is the importance of proper implantation of the vulva and external genitalia?
The vulva and external genitalia act as a barrier to the rest of the reproductive tract. Poor conformation can lead to the introduction of air, feces, and other contaminants which lead to infection.
What are the parts of external genitalia in women?
labia majora, labia minora, hymen, clitoris, urethra, vaginial orifice
What is the importance of the stratified squamous epithelium of the vagina.
It protects the vagina during copulation and thickens during estrus which helps prevent microorganisms from entering the submucosa.
What are the parts of the avian female genital tract.
ovary, oviduct (infundibulum, magnum, isthmus), uterus (shell gland), vagina, cloaca
The avian reproductive organs are only developed on the ___ side.
What is the primary sex organ of the male?
What are layers of the coverings found around the testes?
tunica albuginea, visceral tunica vaginalis, parietal tunica vaginalis
What are the functions of the scrotum?
thermosensor, radiator, protective sac
What structures are located within the testicular parenchyma and mediastinum?
seminiferous tubules, rete testis
List the three parts of the epididymis.
caput (head), corpus (body), caudal (tail)
What is the path of the sperm beginning with the seminiferous tubules through ejaculation?
-seminiferous tubule, rete testis, vas efferentia, caput epididymis, corpus epididymis, cauda epididymis, vas deferens, ampulla, colliculus seminalis, pelvic urethra, penile urethra
What makes up the spermatic cord and what are its functions?
-pampiniform plexus, cremaster muscle, vas deferens; contains vascular, lymphatic and nerves,
-acts as heat exchanger, houses cremaster muscle
What is the pampiniform plexus?
It is a part of the spermatic cord composed of arteries, veins, and nerves that keeps the testes a few degrees cooler than the rest of the body through a counter current exchange mechanism/system.
What is the function of the tunica dartos?
smooth muscle that contracts or relaxes to bring the testes closer to or further away from the body (androgen dependent)
What is the functions of the guabermaculum?
keeps the testes in the proper position within the scrotum
