Reproductive system Flashcards
gonad
organ that produces gamates
gamates
haploid
spermatozoa
ovum / oocyte
zygote =
spermatozoa + ovum
diploid
Ampulla
‘flask’
2nd portion of the fallopian tube
Normal fertilisation
ovum from ovary to ampulla of uterine tube
Perinium
area between the anus and the scrotum / vulva
Peritoneum
lining of the abdominal cavity
forms the pelvic roof
Any abnormal fluid in the peritoneal cavity collects in the
Pouch of Douglas
Uterus layers
3
Perimetrium - thin, peritoneum + connective tissue
Myometrium - wall of uterus, smooth muscle + elastic tissue
Endometrium - inner mucus lining
Fertilisation
ovum into peritoneal cavity
gathered by fimbriae into INFUNDIBULUM of uterine tube
ovum moved along uterine tube by cilia
Implantation of ovum
uterus
Ectopic pregnancy
implants outwit uterine cavity
97% tubal pregnancy
HAEMORRHAGE
Peritonitis from STI
STI spread via uterus & uterine tubes to peritoneal cavity
Female sterilisation
tubal ligation
STIs - damage / occlude uterine tube
Urethra
Tube passing sperm / urine
MALE
Testies origin
posterior wall of the abdominal cavity
Inguinal canal
passage in the anterior abdominal wall that in men conveys the spermatic cord
Vas deferens
duct which conveys sperm from the testies to the urethra
Seminiferous tubules
Sperm produced
Sperm pathway from seminiferous tubules to vas deferens
seminiferous tubules
rete testis
head of the epididymis
tails of the epididymis
dartos smooth muscle
regulate temperature of scrotum
Spermatic cord
vas deferens
testicular artery
paminiform plexus of veins
Accessory reproductive organs
vas defers
seminal glands
prostate gland
penis
Male reproductive stages
- testes in scrotum
- sperm in testes
- sperm: testies –> vas deferens
- vas deferens lie within the spermatic cord
- spermatic cord passes through the inguinal canal –> pelvic cavity
- vas deferens connect with seminal glads to form ejaculatory duct
- R. + L. ejaculatory ducts join together within the prostate gland & drain into the urethra
Seminal glands
produce seminal fluid
Ejaculatory duct contains
Semen = sperm + seminal fluid
Male sterilisation
vasectomy - vas deferens is transected & lumen sutured
