Reproductive system and embryology Flashcards
(39 cards)
what are the mail and female haploid cells?
male - spermatozoa
female - oocyte or ovum
what are the gonads?
testes and ovaries
what is produced after fertilisation?
a diploid cell know as a zygote
where does the ovum travel to during fertilisation?
from ovary to ampulla of uterine tube
where does the pelvic cavity lie?
bony pelvis and is continuous with the abdominal cavity
between the pelvic inlet and pelvic outlet
what is the pelvic floor?
internal wall of skeletal muscle
separates pelvic cavity and perineum
voluntarily contracted
what is the perineum?
inferior to pelvic floor
between proximal parts of the lower limbs
what are the openings in the pelvic floor?
distal alimentary
reproductive and renal tracts can pass through
what is the parietal peritoneum?
lining of abdominal cavity
firmly attached to walls
drapes over pelvic viscera
forms the pelvic roof
what is the pouch of douglas and what is it’s anatomical name?
lowest point of peritoneal cavity
rectouterine pouch
what are the three tracts of the female perineum?
external urethral orifice (urinary tract)
vaginal orifice (female genital tract)
anus (gastrointestinal tract)
what are the main female reproductive organs?
ovaries
what are the female accessory reproductive organs?
uterine tubes, uterus and vagina
what are the three layers of the uterus wall?
perimetrium - outside
myometrium - muscle
endometrium - inside
what is the fimbriae of the uterine tube?
opening into peritoneal cavity
what are the three parts of the uterine tubes?
isthmus
ampulla
infundibulum (funnel)
what is the most common position of the uterus?
anteverted - cervix tipped anteriorly to axis of vagina
antiflexed - uterus tipped anteriorly to axid of cervix
what is the size, shape and location of the ovaries?
almond size and shaped
located laterally in the pelvic cavity
in ovarian fossa
where do the ovaries develop?
posterior abdominal wall and move onto lateral wall of the pelvis
bring all the uterus and nodes when they move
what do the ovaries secrete?
oestrogen and progesterone in response to pituitary hormones
what are the three artery’s in the female pelvis?
ovarian artery
internal iliac artery (biggest supply)
uterine artery
what occurs in each menstrual cycle?
one ovum is released from the surface of the ovary into the peritoneal cavity
the ovum is gathered by the fimbriae into infundibulum of uterine tube
moves along uterine tube by cilia
unfertilised egg is expelled by contractions of the myometrium
where does fertilisation usually occurs?
ampulla
what is an ectopic pregnancy?
fertilised ovum implants out with the uterine cavity
