oocyte or ovum
male haploid cell name
spermatozoa
female gonads
ovaries
male gonads
testes
movement of ovum during normal fertilisation
from ovary to ampulla
movement of many spermatozoa during fertilisation
from testis to vagina
where does the pelvic cavity lie within?
the bony pelvis
what is the pelvic inlet
the way into the pelvic cavity from the abdominal cavity
what is the pelvic outlet
the way into the perineum from the pelvis
what is the pelvic floor made of?
it is an internal wall of skeletal muscle
what does the pelvic wall separate?
the pelvic cavity and perineum
where is the perineum in relation to the pelvic floor?
the perineum is inferior to the pelvic floor
the three openings in the pelvic floor
distal alimentary, reproductive and renal tracts
what is the parietal peritoneum?
the lining of the abdominal cavity which us firmly attached to walls and drapes over pelvic viscera
FEMALES: two pouches formed by the parietal peritoneum?
vesico-uterine pouch and rectouterine pouch
surface name for the urinary tract
external urethral oriface
surface name for the female genital tract
vaginal oriface
surface name for the gastrointerestinal tract
anus
female accessory reproductive organs
uterine tubes, uterus and vagina
three layers of the uterus wall
perimetric, myometrium and endometrium
how is the ovum moved along the uterine tube?
by cilia
where does the fertilised ovum implant during an we-topic pregnancy?
outwit the uterine cavity
how to STI’s effect fertility?
they can reduce fertility by blocking or damaging uterine tubes
what is the name for female sterilisation?
tubal ligation
role of urethra in males
for passing urine and ejaculating sperm
where do testis originate from during development?
on the posterior wall of the abdominal cavity
where do the testis desend to be birth?
the scrotum
vas deferens
the tube that sperm pass through follows the testis into the scrotum
name of muscle that helps to control temperature of seminiferous tubules
dartos muscles
journey of sperm
seminiferous tubules, rete testis, head of epidermis, tail of epididymis to vas deferens
what is all contained within the spermatic cord?
vas deferns, testicular artery and pampiniform plexus of veins
consequence of torsion of the testis
twisting the spermatic cord can disrupt blood supply and cause serious pain
what happens during an erection?
the 3 cylinders of erectile tissue become filled with blood at arterial pressure
male accessory reproductive organs
the vas deferens, seminal glands and prostate gland
where are the testis located?
in the scrotum
where does each spermatic cord pass through?
through the anterior abdominal wall within the inguinal canal to reach the pelvic cavity
constituents of semen
sperm and seminal fluid
what combines to produce an ejaculatory gland?
both vas deferens with the duct from the seminal gland
where do the right and left ejaculatory ducts join together?
within the prostate gland, immediately inferior to the bladder, and drain into the urethra
where does the urethra open?
at the external urethral meatus of the penis
name for male sterilisation
vasectomy
vasectomy process
vas defers is transected and the lumen is sutured closed
