Lecture 22: Reproductive System II Flashcards
What are the functions of the female reproductive system?
- Production of female gametes and sex hormones
- Reception of male gametes
- Site for fertilization
- Transport of fertilized zygote to uterus
- Site of development
- Mechanism of parturition
- Provision of nutrition for the newborn
What are the female sex hormones?
Estrogen and Progesterone
What are the male gametes that the female reproductive system receives?
Spermatozoa
What are the female gametes?
Ova
What are the gonads in the female reproductive system?
The ovaries
What are the ovaries responsible for?
Production of gametes and sex hormones (estrogen and progesterone)
What are the ducts of the female reproductive system?
- Fallopian (uterine) tubes
* Uterus
What is the function of the fallopian (uterine) tubes?
Transport of ovum and fertilization
What is the function of the Uterus?
Implantation and development of foetus
What happens in the uterus if no fertilization occurs?
Menstrual cycles
What is female organ copulation?
Vagina
Which organ is the birth canal?
The vagina
What are the accessory glands of the female reproductive system?
- Pituitary gland
* Mammary gland
What does the pituitary gland stimulate in the female reproductive system?
Oogenesis and ovulation
What is the function of the mammary glands?
Nutrition of newborn
What are the ovaries equivalent to in the male reproductive system?
Testes
What is the difference between the gamete formation between ovaries and testes?
Female gametes are once a month and the ovaries alternate which one produces the gamete
What kind of glands are the ovaries?
Endocrine glands
What do Fallopian (uterine) tubes do?
Take the gamete and bring it to the uterus
Why does the uterus add a new layer every month?
To provide an environment for the development of a foetus
What do the accessory glands in the male reproductive system do?
Produce seminal fluid
What lies over the pelvic cavity in males?
The parietal peritoneum
What separates the abdominal cavity from the pelvic cavity in males?
The parietal peritoneum
What does the parietal peritoneum do to the ovary and uterine tube?
Completely envelopes it
What is it called when there are two layers of peritoneum?
A mesentery
What does a Mesentery do?
Helps anchor something to the body wall or provides vasculature and innervation to the organ
What does the parietal peritoneum going over the uterus do?
Anchors it down and provides vasculature
What does a gamete have to do as a consequence of the ovary being covered by the parietal peritoneum?
The ovum has to pierce through the parietal peritoneum in order for the infundibulum to sweep it over to the uterine tube in order to take it to the uterus
What is the Vestibule the entrance to?
Both urinary and the genital part of the female
What is the end of the uterus?
The cervix
What is different about the cervix part of the uterus?
It is made of a more fibrous tissue
What is the point of protection of the uterus?
The cervix
How does the cervix protect?
If there are any pathogens it ensure that it does not enter the uterus
What is the pouch in the pelvis in males called?
The rectovesical pouch
What are the two pouches in the pelvic cavity of a female?
- Vesicouterine pouch
* Rectouterine pouch
What forms the Vesicouterine pouch?
Between the urinary bladder and the uterus
What forms the Rectouterine pouch?
Between the rectum and the uterus
Where in the body are the ovaries and the fallopian tubes?
They are always posterior
What does the fornix do?
Cups the uterus
What happens at the fornix in terms of semen?
The coagulated semen goes toward the fornix and stays there and gets liquified
When is the Parietal Peritoneum called the Broad Ligament of the uterus?
When it drapes over the parietal reproductive tract including the uterus, the fallopian tubes and the ovaries
What does Ligament mean in terms of parietal peritoneum?
It mean thickening of parietal peritoneum
Why do the ureters need to go deep?
Because they need to go under the broad ligament in order to get to the urinary bladder
Where do the ovaries come from in terms of development?
The abdomen, just like the testes in males
Where does the vasculature of the ovary originate?
In the abdominal aorta
What artery from the abdominal aorta supplies the ovaries?
The ovarian arteries
What do the end of the Ovarian Arteries and Vein need to pierce through and why?
Through the peritoneum in order to access the ovarian
Why do the Ovarian arteries and veins become known as suspensory ligament?
Because they have to pierce the parietal peritoneum
What is the Suspensory Ligament?
The Ovarian Artery and Vein that pierce the parietal peritoneum to get to the ovary
What is found within the suspensory ligament?
Ovarian arteries and veins
What is found within the ovarian ligament?
Nothing it is just a thickening
What anchors the ovary to the uterus?
The Ovarian ligament
What are the projections on the Infundibulum?
Fimbriae
What do the Fimbriae do?
Swoop the gametes into the tube
Where does the Vas Deferens enlarge?
At the ampulla
What is the enlargement of the Fallopian tube known as?
The ampulla
What is the Ampulla the site for in the female reproductive system?
Fertilization
What is the Isthmus?
The part of the fallopian tube that gets closer to the uterus
What is the Intramural?
The part of the fallopian tube that enters the uterus
Where does the Round ligament connect?
From the uterus to the anterior abdominal wall
What are the three divisions of the Broad Ligament?
- Mesosalpinx (Tube)
- Mesovarium (Ovary)
- Mesometrium (Uterus - Endometrium)
What is the Broad Ligament called when it is covering the uterine tube?
Mesosalpinx
What does the Mesosalpinx cover?
The Uterine tube
Which part of the Broad ligament covers the ovary?
The Mesovarium
What is the broad ligament called when it covers the ovary?
The Mesovarium
What is the Broad ligament called when it covers the uterus - endometrium?
The Mesometrium
What is the Mesometrium?
The part of the broad ligament that covers the uterus - endometrium
Where do the Suspensory ligaments of the ovary come from?
The come from the Aorta and the inferior vena cava
What do the Suspensory Ligaments anchor?
The part of the ovary that is associated with abdominal wall
Where in terms of position is the round ligament?
Anterior
What does the round ligament anchor?
The uterus to the anterior abdominal wall
What does the Transverse Ligament do?
Anchors the uterus the lateral walls
What vasculature is found in the Transverse ligament?
The uterine vessels
What does the Ureteral Sacral ligament connect to?

What anchors the uterus posteriorly?
The Uterosacral ligament
