Introduction to the Reproductive System 🗸 Flashcards
Gamete
Haploid cell
male gamete
spermarozoa
Female gamete
oocyte or ovum
Pelvic cavity location
within the bony pelvis between pelvic inlet and outlet
pelvic floor
internal wall of skeletal muscle which separates the pelvic cavity from the perineum
perineum
inferior to pelvic floor, between proximal parts of lower limbs
pelvic roof
formed by parietal peritoneum (lining of abdominal cavity)
peritoneal cavity
space between visceral and parietal cavity
Rectouterine pouch (of Douglas)
double folding of the peritoneum between the rectum and the posterior wall of the uterus, most inferior part of the peritoneal cavity in an upright female
Uteri-vesicle pouch
double folding of the peritoneum between the anterior of the uterus and the bladder
Sterilisation of females
Tubal litigation
tubes clioped, cut or cauterised
Sterilisation of Males
Vasectomy
Vas deferens transected and lumen sutured shut
Torsion of the testis
twisting of the spermatic cord
disrupts blood supply causing severe pain and danger of necrosis
Layers of the uterus wall
perimetrium
myometrium
endometrium
where does fertilisation occur?
ampulla
where does implantation occur?
body of the uterus
What is an ectopic pregnancy?
a fertilised ovum implants outside of the uterine cavity
retrovesical pouch
double folding of peritoneum between the rectum and the bladder
Where do the testes originate during development
the posterior wall of the abdominal cavity
where do the testes descend to
the scrotum (through the anterior abdominal wall
Where are spermatozoa produced?
Seminiferous tubules
Where does the sperm move to after its produced
The rete testis, then the head of the epididymis
What des the epididymis turn into?
vas deferens
what three structures does the spermatic cord contain
Vas deferens
Testicular artery
Pampiniform plexus of veins
Describe how ejaculation works
Sperm moves from the testis via the vas deferens
spermatic cord passes through anterior abdominal wall to reach pelvic cavity
Vas deferens connects to duct from the seminal gland (ejaculatory duct)
Left and right ejaculatory ducts join together within the prostate and drain into the urethra
Urethra opens at the external urethral meatus of the penis
