- uterus (horn, body, cervix)
Which portions of the female reproductive system live in the pelvic cavity?
- vagina
- vestibule
Which portions of the female reproductive system live in the perineum?
- vestibule
- vulva
What are the female gonads that are located caudal to each kidney?
ovary
Which organ normally has an oval shape but the size and the surface can change according with the female cycles?
ovary
The endocrine portion of the ovary produces what hormones?
- estrogen
- progesterone
What organ produces the ova (eggs)?
Ovary
Since the ovary is a solid organ, it lacks what?
a lumen
Is the ovary surface covered by a visceral peritoneum?
No
What is expelled during ovulation and passes into the peritoneal cavity and then travels inside the infundibulum of the uterine tube?
Oocyte
The ovaries are held by what ligament?
suspensory ligament
What is the anatomical structure similar to the uterine tube?
colon
What is the narrow membranous tube with an abdominal opening which receives the ova?
uterine tube (salpinx)
What are the three main portions of the uterine tube?
- infundibulum with fimbriae
- ampulla
- isthmus
The uterine tube connects with which end of the uterine horn?
most cranial end
Describe the path an oocyte takes once ovulated.
- ovulates from ovary
- passes abdominal ostium
- caught by the infundibulum with fimbriae
- passes through ampulla
- fertilization occurs at ampulla/isthmus junction
- passes through isthmus
- passes through tubouterine junction into uterine horn
The uterus is formed by three main layers of tissue. List them.
- perimetrium (visceral)
- myometrium (smooth muscle)
- endometrium (mucosa)
The uterus is formed by four main parts. List them.
- cervix
- uterine body
- two uterine horns (right and left)
Is the uterine body short or long in carnivores?
Short
The uterine body caudally communicates with what structure?
cervix
What is the duct that connects the uterus with the vagina?
cervical canal
What is the exit of the cervical canal oriented toward the body of the uterus?
internal uterine ostium
What is the exit of the cervical canal oriented toward the vagina?
external uterine ostium
What is the double plica of the peritoneum which maintains ovary, uterine tube, and uterus in postision?
Broad ligament
What are the three layers of the broad ligament?
- mesosalpinx
- mesovarium
- mesometrium
What is the peritoneal sac that encloses the ovary and is formed by extensions of the mesovarium and mesosalpinx?
ovarian bursa
Does the opening of the ovarian bursa lie medial, lateral, cranial, or caudal?
Medial
What are the ligaments of the ovary and uterus?
- suspensory ligament of the ovary
- proper ligament of the ovary
- round ligament of the uterus
What ligament connects the ovary to the abdominal wall in proximities to the caudal pole of the kidneys?
suspensory ligament
What short and dense ligament connects the caudal pole of the ovary with the cranial extremity of the uterine horn?
proper ligament
What band of connective tissue extends from the ovary to the inguinal canal?
Round ligament
What structure lies between the cervix and urethral tubercle?
