36
Q

What is the braod ligament?

A

A double layer of peritoneum extends from the sides of the uterus to the floor of the pelvis.

assists with keeping the uterus in position

also provides passage for ovarian vessels, nerves and lymphatics

37
Q

What is the Vagina?

A

A muscular membranous tube
its upper half lies above the pelvic floor
Its lower half lies within the perineum

42
Q

What are the uterine tubes?

A

They are the fallopian tubes
Muscular tubes that are the pathway for sperm to travel to reach the ovum
