Major Roles of Female Reproductive System
Internal Organs of Female Reproductive System
- Ovaries
- Fallopian Tubes
- Uterus
- Vagina
Do A&P Anatomy stuff
check
The shape of an almond
Ovary
She has 2 of them
Ovary
Weight 3 grams
Ovary
fibrous covering (Similar to that of the testes in the male)
Tunica albuginea
Attached by ligaments in the pelvic cavity
Ovary
Attach ovary laterally to the pelvic walls
Suspensory Ligaments
Attach ovary medially to the uterus
Ovarian ligaments
Part of abdomenal serosa
Broad Ligaments
Fold of peritoneum covers
- ovaries
- supporting ligametns
Broad Ligaments
Supports ovary in between
-formed from peritoneum
Mesovarium
Hormones produced by ovaries
Estrogen
Progesterone
Three types of estrogen
estradiol
estrone
estriol
Most abundant estrogen
Estradiol
Each of these consist of
- Oocyte
- Surrounding nurse cells
Ovarian Follicles
an immature egg or female sex cell
oocyte
Two “nurse cells”
but are actually the exact same cells
- Follicle cells
- Granulosa cells
Difference between Follicle cells and Granulosa cells?
Follicle cells only 1 cell layer thick
GRanulosa cells if layer > 1 cell thick
But are the exact same cell
= “Uterine tubes”
= “Oviducts”
Fallopian Tubes
Length 10 cm ~ 4 inches
Fallopian Tubes
Its lumen are lined with cilia
Fallopian Tubes
It is enclosed in braod ligament
Fallopian Tubes
It is medially connected to the uterus
Fallopian Tubes
Laterally
- opens to the peritoneal cavity
- end is flared
- Has fimbriae
Fallopian Tubes
Finger-like projections of Fallopian Tubes that move so as to draw eggs toward the tubes
Fallopian Tubes
Hollow organ
Uterus
Size and shape of an inverted pear (for nulliparous lady)
Uterus
define nulliparous
never had a child
location is midline and superior, posterior to bladder
Uterus
Uterus lateral attachment
Broad ligaments
+ lateral cervical ligametns
Uterus anterior attachment
Round ligaments
Uterus posterior attachments
Uterosacral ligaments
Fundus Isthmus Endometrium Myometrium Epimtrium
5 parts of the body of Uterus
Rounded top of uterus
Fundus
Above and between fallopian tubes
Fundus
Slightly narrow area between fundus and cervix
Isthmus
Inner uterus layer with mucosal tissue
Endometrium
Middle uterus layer with smooth muscle
myometrium
Myo… muscle. MEH HEH!
Outer uterine layer
- serous layer of tissue
- part of visceral peritoneum
Epimetrium
Portion of uterus that protrudes into the vagina below
Cervix
Cervical os
Opening from uterus from vagina
aka “birth canal”
Vagina
Connects exterior of the body to cervix of uterus
Vagina
Hollow, stretchable tube
Vagina
8-10cm (3-4 inches) long
Vagina
pH 3.5-4
Vagina
Walls are
- thin
- muscular
- stretchable
Vagina
partially covers opening from surface of body
Hymen
Thin fold of mucosa
Vascular
Hymen
opening from surface of body
=Introitus
External Organs of Female Reproductive System
Vulva
Breasts
Between the pubic bone and anus
Vulva
Includes: Introitus Hymen Bartholin's Glands Urethral Meatus Clitoris Labia Minora Labia Majora Mons Pubis
Vulva
BTW which of those list is NOT connected to reproductive system in any way?
Urethral Meatus.. but it’s just there
=vaginal orifice
=Introitus
=Greater Vestibular Glands
Bartholins’ Glands
Secrete mucus-like lubricating fluid
Bartholins’ Glands
Erectile Tissue
- analogue of male penis
- sensitive to touch
- swells with blood during sexual excitement
Clitoris
Located behind anterior junction of labia minora
Clitoris
“small lips”
Labia Minora
Located medial to labia majora
Labia Minora
Joined anteriorly in midline
Labia Minora
=area between labia minora
=Vestibule
Contains
- clitoris
- urethral orifice
- vaginal orifice
- orifices of ducts of Bartholin’s glands
Labia Minora
“large lips”
Labia Majora
Contain
- fatty deposits
- numerous glands
Labia Majora
Covered with (outer surface)
- Pigmented skin
- Hair (after puberty)
Labia Majora
Fatty, rounded area
Covers Pubic Symphysis
Mons Pubis
Main Purpose - Milk Production
Breasts
Origin: Modified Sweat Glands
Breasts
Size are similar to male initially
Breasts
Increase in size during puberty, when stimulated by female hormones, esp. estrogen
Breasts
Have 15-25 lobes or divisions
Breasts
Each lobe has several lobules
Breasts
clusters of grape-like arrangement of milk-producing cells within each lobule
Alveolar Glands
Formed from the interlobar connective tissue
Suspensory Ligaments
Breasts
Attach to
-underlying muscle fascia posteriorly
Suspensory Ligaments
Breasts
Attach to
-Overlying dermis, anteriorly
Suspensory Ligaments
Breasts
Provide natural support for breasts like built-in brassiere
Suspensory Ligaments
Breasts
covers mammary gland
Adipose Tissue
Breasts
Increasees in amounts
- during puberty
- under influence of female hormones
- -especially estrogen
Adipose Tissue
Breasts
Its amount is largely responsible for breast size, not with amount of milk it can produce for baby
Adipose Tissue
Breasts
