Lecture 4- Reproductive System Flashcards
What are gametes and where are they produced?
haploid cells which are produced in the gonads- testes and ovaries
what is fertilisation?
when the diploid zygote is produced by the fusion of 2 opposite sex gametes,
where does the pelvic cavity lie and what is it continuous with?
within the bony pelvis, continuous with abdominal cavity.
what is the pelvic floor?
internal wall of a skeletal muscle, it separates the perineum with the pelvic cavity
why does it contain gaps
to let different tracts through
what is the pelvic roof
this is formed by a thin lining of the abdominal cavity (firmly attached to walls, drapes over organs) called the parietal peritoneum
where is unusual fluid collected in the peritoneal cavity?
in the pouch of Douglas
what actually is the peritoneal cavity
between peritoneum and visceral peritoneum
what is the perineum between
proximal parts of the lower limbs
name the elements of the surface perineum of a female
external urethral orifice, anus, labii, vaginal orifice
what is the 1 true female reproductive organ
ovaries
what are female accessory reproductive organs
uterine tubes, uterus, vagina
what are the 3 layers of the uterus called and locate them
perimetrium (central area), endometrium (internal area), myometrium (everything else)
where do the fimbriae open in to
the peritoneal cavity
talk through the fertilisation/ menstrual process
ovum develops in ovaries, every menstrual cycle 1 ovum is released from the ovaries into the peritoneal cavity.
it is then gathered by fimbriae and cilia push the ovum along the uterine tube. the ovum (and parts of endometrium) are expelled by contractions of the myometrium.
