Q

how many eggs produced for potential conception

Study These Flashcards
A

300 mature eggs

24
Q

ovaries produce the hormones

Study These Flashcards
A

Estrogen & Progesterone

25
fallopian tubes measure
8-13cm
26
what does millions of cilia line
fimbriae and and interior of fallopian tubes
27
what does the cilia do
a beat in waves 100s of times a sec | catching the egg at ovulation and moving it through the tube to the uterine cavity.
28
Fertilization typically occurs in
fallopian tube
29
UTERUS IS MADE UP OF THREE LAYERS
Perimetrium Myometrium Endometrium
30
Perimetrium
``` Outer connective layer serous layer(part of visceral peritoneum) ```
31
Myometrium
smooth muscle | no submucous layer
32
Endometrium
internal MUCOSAL layer
33
Basal (stromal layer) where. .. attaches. ..
just under myometrium | functional layer to myometrial tissue
34
Functional zone where. .. contains. .. undergoes. ..
- layer closest to the cavity - majority of glands. - changes in monthly cycle in thicker portion
35
functions of Uterine glands
synthesize/transport and secrete subs needed for survival&development of the embryo or fetus
36
Basal (stromal layer) Makes
functional layer
37
functional layer builds up
after the end of menstruation (estrogen) during the | first part of the menstrual cycle -follicular phase
38
STAGES OF THE MESTRUAL CYCLE
1. Menstruation 2. follicular phase 3. proliferative phase 4. Ovulation 5. luteal phase 6. secretory phase
39
the peritoneum reflected from
sup surface of bladder onto fundus and body of uterus
40
the space inbetween this reflection is called
vesico-uterine pouch
41
pouch of douglas / rectouterine pouch is the reflection between...
peritoneum on the post part of uterus and ant part of rectum
42
round ligaments pass thru
ingunal ligament and out to the mons pubis
43
broad ligament is ... ovary suspended within..
a folded peritoneum (that moves at the side of uterus to the side of t pelvic wall) peritoneal cavity by a fold of peritoneum called the mesovarium
44
broad ligament is made up of 3 ligaments
mesometrium mesovarium mesosalpinx
45
supports of uterus upper middle lower
1. round ligament and broad ligament 2. transverse ligament, pubovesical,Uterosacral 3. Levator ani, coccygeus and Perineal body
46
Pubovesical attaches function
1. neck of bladder to pubic bone | 2. maintain normal angle of vagina @45 degree
47
Uterosacral 1. attached 2. contains 3. function
from the cervix to the middle of sacrum lymphatics helps prevent prolapse
48
nerve supply
Parasympathetic S2,3, 4 | Sympathetic to T11 and T12,.... via hypogastric plexus
49
BLOOD SUPPLY TO REPRODUCTIVE SYSTEM uterine and vaginal from ... ovarian from.. Ant and post arcuate run ...
I. Iliac abdominal aorta in middle layer of uterus
50
Right ovarian vein drains into | Left ovarian vein drains into
IVC | Left renal vein
51
UTERUS BLOOD SUPPLY | veins are found..
under arteries
52
Radial branches connect
arcuate to straight
53
what do Arcuate arteries do
encircle endometrium
54
Straight arteries deliver blood to what zone
basilar
55
Spiral branches deliver blood towhat zone
functional
56
ovarian Lymphatics into
paraaortic glands at L2
57
THE CARDINAL LIGAMENT PASSES FROM THE
cervix to the lateral pelvic wall
