superior
What are the 3 spaces of the female pelvis?

What lies in the true pelvis between the bladder and the rectum?
Uterus
The uterine wall is composed of what 3 layers?
endometrium (innermost), myometrium (middle layer-muscular), serosa (outermost— also called perimetrium)
The uterus is divided into how many sections?
4
What are the 4 sections of the uterus?
fundus, body, isthmus, cervix
The pouch that surrounds the cervix is the:
Fornix
Lower uterine segment (LUS) is the same as the:
Isthmus
What are the 4 main positions of the uterus?
anteverted, anteflexed, retroverted, retroflexed
The positions of the uterus depend on:
What level of the uterus bends — vert= bent at cervix — flex = bent at the body
What is the most common position of the uterus?
Anteverted
With an empty bladder, the corpus and fundus are tilted anteriorly: (horizontal when patient is erect)
What position of the uterus is when the corpus and fundus are bent at a greater anterior angle?
Anteflexed
What position of the uterus is when the corpus and fundus are tipped posteriorly?
Retroverted
What position of the uterus is when the uterus is bent at a greater posterior angle?
Retroflexed
Which artery/vein feeds the pelvis?
Internal iliac artery/vein
IIA is also called:
Hypogastric artery
Which artery branches off the internal iliac artery that supplies blood to reproductive organs?
