Clinical anatomy of the reproductive system Flashcards
what is a gamete
a haploid cell
male- spermatozoa
female- oocyte
where are gametes produced
gonads
male- testes
female- ovaries
where does the pelvic cavity lie
within the bony pelvis between the pelvic inlet and pelvic outlet, continuous with the abdominal cavity
what is the pelvic floor
internal wall of skeletal muscle which separates pelvic cavity and perineum
what are the openings in the pelvic floor
distal alimentary
reproductive and renal tracts can pass through
what is the perineum
inferior to pelvic floor, between proximal parts of lower limbs
what is the pelvic roof formed by
parietal peritoneum
what is the parietal peritoneum
lining of abdominal cavity
firmly attached to walls
drapes over pelvic viscera
what is the male reproductive organ
testes
what are the accessory reproductive organs
vas deferens, seminal glands, prostate gland and penis
how do testes develop
during development they originate on the posterior wall of the abdominal cavity, by birth they’re at the scrotum
where are sperm produced
seminiferous tubules
describe the seminiferous tubules
1oc below core body temp
dartos muscle helps to control temp
1500 every second, take 64 days to mature
what happens after the sperm are produced in the seminiferous tubules
sperm pass to rate testis
then into the head of epididymis
this then becomes the vas deferens
what does the spermatic cord contain
vas deferens
testicular artery
pampiniform plexus of veins
what is torsion of the testes
twisting of the spermatic chord
disrupts blood supply
medical emergency
testicular necrosis
where are the testes located
scrotum
where do sperm pass through
vas deferens (each lies within the spermatic chord)
where does the spermatic chord pass through
anterior abdominal wall within the inguinal canal to reach the pelvic cavity
within the pelvis what does each vas deferen connect with
seminal gland to form an ejaculatory duct containing semen
what do the l and r ejaculatory ducts join together within
prostate gland
where do the l and r ejaculatory ducts drain into
urethra
where does the urethra open
external urethral meatus of the penis
what are males steralised
vasectomy
what is a vasectomy
vas deferens is transected and lumen suture closed
what are the 3 tracts of the female perineum
urinal- external urethral orifice
genital- vagina orifice
gi- anus
what are the 3 layers of the uterus wall
perimetrium
myometrium
endometrium
where do the ova develop
ovaries
where is the ovum released into
peritoneal cavity
what is the ovum gathered by
fimbriae into infundibulum of uterine tube
how are the ova moved along the uterine tube
cilia
what is a female steralised
tubal ligation
what is tubal ligation
both uterine tubes are clipped, which blocks the lumen
what happens during menstruation
unfertilised ovum is expelled by the contractions of the myometrium
