Reproductive Anatomy Flashcards
WHat is the vesicouterine pouch between the uterus and bladder
pouch between the uterus and bladder
What is the perimetrium
the surrounding lining of the uterus
what is the ampulla
the uterine tube that is the site of fertilisation
what are fallopian tubes
uterine tubes
what muscle is present in the myometrium
smooth muscle
what is an anteverted uterus
cervix is tipped anteriorly relative to the axis of the vagina
what is an anterflexed uterus
where the uterus is tipped anteriorly to the axis of the cervix
where are the ovaries located
laterally in the pelvic cavity
the ovarian artery is derived from the abdominal artery, true or false
true
because during development the ovaries are on the posterior abdominal cavity and receive nutrients via AA
describe the anatomical journey of the ova during menstruation
at each cycle an ovum is released from the surface of the ovary into the peritoneal cavity, it is gathered by fimbriae that waft the ovum into the infundibulum of the uterine tube and then moved up the tube with cilia to the ampulla where fertilisation would occur, in this absence the ovum is expelled by contractions of the myometrium
What are two types of ectopic pregnancies
tubal pregnancy (97%)
abdominal pregnancy
What is the dartos muscle
smooth muscle that regulates the testes temperature (wrinkle if too cold)
What is the spermatic cord
vas deferens, testicular artery, pampiniform plexus of veins
What is the anatomical passage for the sperm from the testes to the orifice
from the seminiferous tubules and into the rete testis, into the head of the epididymis which becomes the vas deferens and then transports sperm into the urethra and out
What is torsion of the testes
twisting of the spermatic cord (disrupts blood supply causing testicular necrosis)
How is semen formed
each vas deferens containing sperm, connects with a duct from the seminal gland to form an ejaculatory duct (both left and right) therefore containing a combination of sperm and seminal fluid
What is a form of male sterilisation
vasectomy - cauterising or clipping of the vas deferens
what is a form of female sterilisation
tubal ligation - cauterisation or sealing of the uterine tube (closes up the lumen)
What is the pelvic roof
A thin transparent membranous layer that also secretes fluid which causes the organs to move against each other without friction
What is the perineum
the outer layer of skin
Where is the perineum
sits inferior to the pelvic floor between the proximal parts of the lower limb (or groin)
Where is the pelvic cavity
lies within the bony pelvis and continuous with the abdominal cavity, pelvic cavity lies inferior to the abdominal cavity
What is the pouch located between the rectum and uterus
rectouterine pouch
Female perineum consists of what?
external urethral orifice
vaginal orifice
anus
what does the male perineum include
the scrotum (contains the testes), and penis of which orifices include the anus and prepuce where the urethra passes into containing both urine and sperm ejaculation
why is it important that the temperature is maintained in the testes?
the sperm have a very narrow optimum range and spermatogenesis occurs in the seminiferous tubules in the testes
