Femal Reproductive System Flashcards
What type of organ is the breast?
Accessory organs
What type of gland is the breast compared with?
Breasts are like modified sweat glands that produce milk instead of sweat.
What is the mammary gland divided internally into?
Lobes (about 15-20)
What do the lobes of the breast contain?
Sacks, individual little bundles called lobules.
What do the lobules of the breast contain? What do they produce?
Alveolar. The cells within the alveolar produce breast milk.
Where else in the body can you find alveolar?
In the lungs
How is the milk created by the alveolar cells collected?
All the breast milk is collected into lactiferous ducts.
Does every lobe have a lactiferous duct?
Yes every lobe has a duct that connects it to the external environment.
What is the breast made mainly of?
Adipose tissue
What is connect to the lactiferous duct? What is the function of this structure?
The lactiferous duct is connected to a lactiferous sinus. It will carry the milk produced by the lobes to the nipple.
What is the function of the nipple?
The nipple has the openings for the lactiferous sinuses.
What is the areole?
Darkened area surrounding the nipple doesn’t play a part in releasing milk.
On non pregnant women how is breast sized determined?
Adipose tissue determines breast size. (Glands in the breast are small don’t affect size in non pregnant women)
Which hormones are involved in increasing the size of the breast and the start of the grandular tissue?
During pregnancy the hormones involved in making the mammory gland tissue to become active are PROLACTIN and HUMAN PLACENTAL LACTOGEN.
What hormone is involved in breastfeeding?
When the infant is feeding on the breast oxytocin is real released.
What releases oxytocin?
Pituitary gland
What does oxytocin do?
Triggers the contraction of smooth muscle in the walls of the lactiferous ducts and sinuses so that it can help eject milk through the nipple.
Draw the location of the uterus in the female.
You should have the uterus in between the bladder and the rectum. So bladder then rectum posterior to it (aka behind it) and anterior to the rectum. (Aka the rectum is behind the uterus or you can say the uterus is in front of the rectum)
Where is the ENTIRE reproductive tract located?
Inside the pelvis.
In a female what is the urogenital diaphragm and what does it tell us?
The urogenital diaphragm is a landmark between what’s considered external genitalia and what’s considered internal.
The ovaries in a women are equivalent to what in a male?
Gonads
Where are the ovaries located?
Lateral to the uterus.
Where is the vagina located?
Inferior to the uterus.
In a female what is considered external genitalia?
Labia majora, labia minora, part of the clitoris
What is the clitoris?
Erectile tissue
What occurs in a male with his reproductive organs that does occur in women.? (Think in the context of the abdominal wall)
In a male a lot of those reproductive organs pierce through the anterior abdominal wall and hang down into the scrotum but that situation does not occur in the female.
Name the internal genitalia of a woman.
- Uterus
- Ovaries
- Vagina
The ovaries in females is equivalent to what in males?
The Testis (gonads) in males
Where is the vagina located?
The Vagina is inferior to the uterus, and is open to the external environment ( via the vaginal orifice)
What type of tissue is the clitoris composed of?
Clitoris (which is colored blue in the models) is erectile tissue.
What is the inferior view aka superficial part of the woman (between the legs) referred to as?
Perineum
What is the mons pubis?
Stands for mound above the pubic bone. It’s a fat pad that sits on top of the two pubic bones and is typically covered with hair which is where the term pubic hair comes from.
What is the correct term for the external genitalia that we casually call lips (the outermost lips)?
Labia majora and we have 2 sets both a right and left.
What is the correct term for the external genitalia that we casually call lips (the innermost lips)?
Labia minora and we have 2 sets both a right and left.
Describe the labia majora versus labia minora in terms of hair. Describe what they resemble that is on our face.
The labia majara is typically covered with hair, the labia minora is smoother, hairless. They’re also similar in appearance to the lips on the face, they have a pink hue and are highly sensitive, highly innervated.
What is the vulva?
The general region that is outside of the body that is seen superficially I.e includes the labia majora and labia minora. We typically call this the vagina DO NOT call it that.
Does the female like the male have a tip on their erectile tissue?
Yes
What is the tip on a females erectile tissue called?
Glans of the clitoris
What is the clans of the clitoris?
The portion of the clitoris that is external (the rest of it is internal inside the body) Aka this is the part sticking out onto the external environment.
What covers the glans of the clitoris?
It is covered by foreskin and that foreskin is referred to as the prepuce.
What is the prepuce?
The prepuce is what covers the glans of the clitoris.
What is the vestibule?
This is the opening between the two labia minora aka the door to the vagina or the vaginal orifice.
What is the opening where urine comes out for a female called?
External urethra orifice
Is the external urethra orrifice part of the reproductive system?
No it is not!
Which non-reproductive structure is often confused with other structures in this perineum region?
The external urethral orifice
Is Genital development in males and females the same? Why?
Yes, up until 7 weeks external genitalia looks the same in a male or female fetus. Because they derive from the same rudimentary structures.
The clitoris is homologous to what in a male?
the clitoris in a female is homologous to the penis in the male. it’s simply that the penis is longer and the clitoris is smaller.
What is homologous to the labia majora in a female?
The labia majora in a female is equivalent to the scrotal skin in a male.
What is the difference between the ovaries and the scrotum?
The difference is that the ovaries don’t descend out of the body and into the skin surrounding that area and forming the scrotum whereas they do you in the male.
Is the prepuce a homologous structure?
Yes
What is the clitoris formed from?
Erectile tissue
Which part of the clitoris is most internal?
The crus of the clitoris
The erectile tissue that forms the clitoris is very similar to what ?
the corpus cavernosa in males
How is the clitoris different from the corpus cavernosum in males?
The difference is that the glans of the clitoris is the only portion that is external whereas in a male a large portion of the corpus cavernosum is external.
The corps spongiosum in males is called what in females?
It’s called bulb of the vestibule
There’s corpus spongisosum in the penis and the clitoris is homologous to the penis so is the spongiosum in females found in the clitoris?
No. Corpus spongisum is also an erectile tissue, however it’s not part of the clitoris.
During sexual intercourse what two things become engorged with blood and become highly sensitive?
The bulb of the vestibule and the corpus cavernosum.
What two structures are erectile tissue in the female?
The bulb of the vestibule and the corpus cavernosum.
What causes the clitoris to become erect?
The corpus cavernosum
Where is the bulb of the vestibule located?
under the labia majora
What is the greater vestibular gland? When is it most active?
Accessory glands that lubricate the outside of the vagina this of course would become most active during sexual arousal.
What is the greater vestibule gland equivalent to in males?
equivalent to the bulbourethral glands in males.
What happens to the glans of the clitoris during sexual arrousal?
Most of the time the glans is not visible however during sexual arrousal it becomes erect and the clans will pop out or stick out of the prepuce.
What is the most sensitive and most innervated part of the external genitalia? When is it exposed?
The glans of the clitoris is the most sensitive most highly innervated part of the external genitalia and once aroused it is exposed during sexual intercourse.
Name the two muscles of the middle perineum layer
Bulbospongiosus muscle and the ischiocavernosus muscle
What does the ischiocavernosus do?
Maintains clitoral erection just as it would maintain penile erection.
What does the bulbospongiosum muscle do in females?
The bulbospongiosus constricts the vaginal orifice and assists with orgasm.
What does the internal prudential artery and vein do?
the internal pudendal artery and vein provides the blood supply and drainage for all the external genitalia .
What does the prudendal nerve do?
prudendal nerve which provides innervation or sensation to this deeper layer of the perineum
What muscle is worked dural kegal exercises?
Bulbospongiosus muscles
Both male and female reproductive systems have two same functions what is a third that they don’t share?
Nourish, support, & give birth to a human fetus.
What functions of the reproductive system do males and females both do?
1-Produce reproductive cells (gametes)
2-Produce sex hormones that influence structure and function of all other systems
What at the 4 basic functional groups (parts) of the female reproductive system?
1-Gonads
2-Reproductive tract
3-accessory glands
4-external genitalia
Think GEAR
What are female gonads?
Gonads: Ovaries produce the ova (which produce estrogen, progesterone and testosterone)
What does the female reproductive tract do?
Reproductive tract: transports and nourishes the ova during ovulation
What is part of the reproductive tract?
uterine tube aka the fallopian tubes
the uterus
the vagina.
What are the parts of the accessory glands?
Accessory Glands: Includes the mammary gland (in the breast) and the greater vestibular glands
What is part of the external genitalia ?
