The ___________ is the funnel end of the oviduct that captures the oocyte after ovulation
The surface of the infundibulum is covered with many velvety, finger-like projections called fimbriae, which increase the surface area of the ovary near the time of ovulation. Fimbriae then pass the egg to the ostium of the ampulla
Fertilization almost always occurs at the ___________
What species does this belong to? Note the corkscrew appearance to the cervix.
The __________ is the part of the female reproductive tract that serves as the major barrier to sperm transport.
This part of the female reproductive tract is common to both the urinary and reproductive tract:
Placentomes are seen with which type of placentation?
In what species can we see placental scars if the animal has ever been gravid?
There are four types of follicles present within the ovary. The smallest, most immature follicles are the __________
The oocyte (egg) within the primordial follicle is surrounded by a single layer of flattened (squamous) cells. The primordial follicle will develop into a slightly more advanced follicle called the primary follicle.
The __________ follicle is characterized by having an oocyte that is surrounded by a single layer of cuboidal epithelium or follicular cells
Females are born with a lifetime supply of primordial and primary follicles. Primary follicles either develop into a more advanced secondary follicle or they degenerate.
A __________ follicle is characterized by having two or more layers of follicle cells, but without an antrum or cavity.
In general, the oocyte within a secondary follicle is characterized as being surrounded by a relatively thick translucent layer called the zona pelucida.
The __________ follicle is characterized by a fluid-filled cavity called the antrum
The corpus luteum produces __________ and is essential for the maintenance of pregnancy
The infundibulum leads directly into a thick portion of the oviduct called the __________
The ampulla occupies 1/2 or more of the oviductal length and merges with the isthmus of the oviduct.
Ovulation in the mare occurs in a specific anatomical location called the __________
Which animal has a cervix that requires this specialized AI pipette?
The cow, sheep, goat, mare, dog and cat all have a what anatomical type of uterus?
In which species do we expect to see a bicornuate uterus with highly developed uterine horns?
Dogs, Cats, Pigs
The __________ serves as a storage organ for spermatozoa prior to ejaculation
tail of the epididymis
Which of the following is true of the male accessory sex glands?
- Bulls, Stallions, & Small Ruminants have prostate, vesicular gland, and bulbourethral gland
- Cats don’t have an ampulla or vesicular glands
- Boars don’t have an ampulla
- Dogs only have a prostate
- All of the above
All of the above
The __________ are enlargements of the ductus deferens that open directly into the pelvic urethra
The enlargement is the result of a dramatic increase in the mucosa within the ampulla.
The testicular veins in the spermatic cord branch into an elaborate network called the __________
This plexus eventually forms a single vein that runs into the caudal vena cava.
In most mammals, the testes must be ______ ˚C cooler than the body in order for spermatogenesis to occur
The complex, intimate network of the spermatic artery and the spermatic veins forms a countercurrent heat exchanger
In what species do we see a fibroelastic penis?
Bulls, boars, rams
In species with a fibroelastic penis, there is an S-shaped configuration along the shaft of the penis called the sigmoid flexure
In what species do we see a musculovascular penis?
Stallion, dog, men
The shaft of the penis has an area of spongy, erectile tissue known as the ___________ that makes up the majority of the penile interior
In the ventral portion of the penis immediately surrounding the penile urethra, there is another spongy erectile tissue called the corpus spongiosum
The glans penis of the ________ contains a single stiff spiny appendage called the cartilaginous process
The function is not known but this modification can cause damage to the cervix and uterus if excessive copulation is allowed.
The third or final phase of spermatogenesis is the __________
No further cell divisions take place during this phase.
The duration of spermatogenesis varies between species. How long is spermatogenesis in the bull?
The duration of spermatogenesis varies between species. How long is spermatogenesis in the stallion?
The duration of spermatogenesis varies between species. How long is spermatogenesis in the ram?
The duration of spermatogenesis varies between species. How long is spermatogenesis in the boar?
