Female reproductive system Flashcards
FEMALE REPRODUCTIVE SYSTEM FUNCTIONS:
- Production and transport of ovum
- Production of hormones
- estrogen
- progesterone
- relaxin
- inhibin
- Nurture the developing zygote
- Diamond shape
- Contains genitalia and anus
PERINEUM
BOUNDARIES:
Anterior
Lateral
Posterior
- pubic symphysis
Anterior boundaries
- ischial tuberosities
Lateral boundaries
- coccyx
Posterior boundaries
EXTERNAL GENITALIA
- MONS PUBIS
- LABIA MAJORA
- Labia Minora
- VESTIBULE
- mound of fats beneath and symphysis pubis
- puberty….. pubic hair
MONS PUBIS
- skin fold with hair
- pudendal cleft - space in between labia majora
- sweat, sebaceous glands, apocrine
- homologue of male scrotum
LABIA MAJORA
- Skin fold, hairless
- Few sweat gland
- Many sebaceous gland
Labia Minora
- space between labia minora
VESTIBULE
- frenulum and prepuce; homologue of the penis
Clitoris
- secretes mucus
- homologue to prostate
- vaginal orifice- guarded with hymen
paraurethral glands (skene’s gland)
VESTIBULE
a. Clitoris
b. Urethral orifice
c. paraurethral glands (skene’s gland)
d. bartholin’s (greater vestibular gland)
II. INTERNAL GENITALIA
PARTS OF INTERNAL GENITALIA
- VAGINA
- UTERUS
- FALLOPIAN TUBE
- OVARY
- fibromuscular canal
- lined by mucous membrane
- rugae
- hymen
- acidic
- fornices
VAGINA
FUNCTIONS OF VAGINA
- copulation
- Birth canal
- Outlet of menstrual flow
- receives the penis during sexual intercourse
copulation
UTERUS Parts:
- Fundus
- Body
- Cervix
- above attachment of fallopian tube
Fundus (Uterus parts)
- from attachment of fundus to isthmus uteri
Body (Uterus parts)
- distal portion with canal
- surrounded by proximal part of vaginal canal
Cervix (Uterus parts)
LAYERS OF THE UTERUS
- Perimetrium
- MYOMETRIUM
- ENDOMETRIUM
- outer covering
- derived from peritoneum
- forms the uterovesical and rectouterine pouch
Perimetrium (LAYERS OF THE UTERUS)
- Middle layer
- Smooth muscles
- Thickest at the fundus and thinnest at the cervix
- Response to oxytocin stimulation during labor and delivery
MYOMETRIUM (LAYERS OF THE UTERUS)
- Innermost
- Contains endometrial glands
- Response to estrogen and progesterone that prepares the uterus for possible implantation
ENDOMETRIUM (LAYERS OF THE UTERUS)
ENDOMETRIUM Layers:
- Stratum functionalis
- Stratum basalis
- slough off during menstruation
Stratum functionalis (ENDOMETRIUM Layers)
- does not slough off during menstruation
- gives rise to new stratum
Stratum basalis (ENDOMETRIUM Layers)
