Structure/Function:F Flashcards
what is the mons veneris/mons pubis
-pad of fatty tissue over the pubic bone
lots of nerve endings
libia majora
outer lips
- elongated folds of skin
- appearance varies
- usually close to protect the vaginal opening
- sexual excitment, they seperate and flatten
- with multi kids, it may not open completely
Libia minora
inner lips
- 2 hairless folds of skin
- variation
- rich in sensory receptors
- colour change with arousal and orgasm
labiaplasty
surgical modification of labis
clitoris
prepuce, shaft, glans, nerve endings
- prepuce (hood over clitoris)
- shaft (2 cavernous bodies that fuse together)
- glans (spongy body that engorges with blood when aroused, enlarging the clit.)
- lots of nerve endings
vaginal orifice/introitus
- the vaginal opening
urethral orifice
- connects bladder to external
hymen
what, pain, blood, and 5 types
- partly “seals” vaginal opening
- min. pain and bleeding
1. annular (doesn’t cover hole)
2. septate (covers hole in the middle)
3. cribriform (covers multi pts, but not all)
4. imperforate (sealed off hole)
5. parous inroitus (after childbrith, material is teared and stretched)
first intercourse
pain and arousal
- pain is from muscular tension and multi attempts at penetration
- arousal is influenced by learning and experience
vagina
purpose, sensitivity, dilation
- receives semen
- menstrate discharge
- birthing cannal
- muscular tube that can dilate
- sensitivity (outer = 1/3 sensitive, inner = 2/3 w/o pain receptors)
vaginal mucosa
vagina inner lining
- sim to inside of mouth
- corrugated, fleshy, soft
- responsive to hormone changes
vagina
lub, diameter, defense
- vaginal lubrication from blood engorgement (plasma leaked from blood vessels)
- diameter under voluntary control (puboccygeal muscle)
- built-in defense mech v. infection (Doderlein’s bacilli killed by antibiotics)
Uterus
- fertilized egg develops in uterus
- ## inverted pear, tilted
endometrium
pt. of uterus
- glands and network of blood vessels
- menstrual cycle
myometrium
pt. of uterus
- muscle tissue
- push fetus out
- contracts during orgasm and breast feeding
perimetrium
pt. of uterus
elastic fibrous coating
cervix
pt. of uterus
- hangs into the vagina
- special glands on linning of cervix
- mucus plugs opening
germ cells (ova) and hormones
pt. of ovaries
- almond shaped
fallopian tubes
pt. of ovaries
- not directly connected to ovary
follicles
pt. of ovaries
- each contains 1 ovum
- varies stages of development
- all you will ever have at birth
- 400K; 20-60K at puberty
hormones
- estrogen and progesterone
- male androgens
fallopian tubes
- ovum must find uterine tube opening (mysterious attraction to tube)
- not simply hollow tube
Cillia
pt. of fallopian tube
- tube sweep ovum
- sperm work against flow
fertilization
pt. of fallopian tubes
- typically in tube
- implantation in endometrium
- develops into fetus in uterus
the fallopian tubes are
1. directly connected to the corresponding ovary
2. loosely connected to the corresponding ovary
3. completey hollow
4. 2 of these
2.loosely connected
breasts are pt in what
- reproduction
- erotically sensitive
- erotic object in culture
lobes
pt. of breasts
- clusters of glandular tissue
- each has seperate duct opening
- separated by loosely packed fibrous and fatty tissue
- size in relation to fatty tissue
nipple
pt. of breasts
- smooth muscle but contracted they go erect
- areola darkens with pregnancy
- endowed with nerve endings
surgeries
pt. of breasts
- breast implantations
- breast reduction (health problems, breast feeding issues, sensitivity loss, scarring)
- liposuction (nonsurgical)
