Female Pelvis Flashcards
What is the primary blood supply to the female pelvic viscera?
Internal Iliac Artery
The Internal Iliac Artery supplies pelvic viscera and exits the pelvic cavity to supply gluteal, medial thigh, and perineal regions.
What are the branches of the female Internal Iliac Artery? (11)
- Iliolumbar
- Lateral Sacral
- Superior Gluteal Artery
- Inferior Gluteal Artery
- Internal Pudendal Artery
- Uterine Artery
- Vaginal Artery
- Obturator Artery
- Umbilical Artery
- Superior Vesical Arteries
- Middle Rectal Artery
These branches supply various regions and structures within the pelvis.
True or False: The round ligament of the uterus connects the ovary to the uterus.
False
The ligament of the ovary connects the ovary to the uterus.
Fill in the blank: The __________ is the female homolog of the scrotum.
Labium Majora
The labia majora are rounded folds of integument forming lateral boundaries of the pudendal cleft.
What structure is described as the ampulla of the rectum?
The dilated terminal part of the rectum
It serves as a temporary storage site for feces before elimination.
Identify the structure that contains the ovarian artery and vein.
Suspensory Ligament of Ovary
This ligament supports the ovary and contains the blood vessels supplying it.
What structure connects the ovary to the uterus?
Ovarian Ligament
It is a fibrous structure that attaches the ovary to the lateral side of the uterus.
Which artery supplies the uterus?
Uterine Artery
The uterine artery is a key vessel supplying blood to the uterus.
What is the function of the fimbriae?
To help guide the ovum from the ovary into the uterine tube
Fimbriae are finger-like projections that play a crucial role during ovulation.
Where does the piriformis muscle originate?
Anterior aspect of sacrum
The piriformis exits the pelvis via the greater sciatic foramen.
True or False: The internal pudendal artery exits the pelvic cavity via the lesser sciatic foramen.
False
The internal pudendal artery exits via the greater sciatic foramen.
Fill in the blank: The ________ is a landmark for some branches of the internal iliac artery exiting the pelvic cavity.
Greater Sciatic Foramen
This foramen is crucial for the passage of nerves and vessels from the pelvis to the lower limb.
What are the landmarks of the superior gluteal artery and where does it exit the pelvic cavity?
- typically found between the lumbosacral trunk and S1
- exits the pelvic cavity via the greater sciatic foramen along the superior border of piriformis
What are the landmarks of the inferior gluteal artery and where does it exit the pelvic cavity?
- Typically found between S1 and S2
- Exits via the greater sciatic foramen along the inferior border of piriformis
How can the obturator artery be identified?
- branch off the internal iliac artery
- Exits pelvic canal through the obturator foramen (located more anterior and inferior than greater/lesser sciatic foramen)
How can the umbilical artery be identified?
- travels upward toward umbilicus
- gives off superior vesical arteries that supply the bladder
Identify the encircled arteries
Red: iliolumbar artery
Blue: lateral sacral artery
Identify the encircled arteries
Blue: superior gluteal artery (cut)
Red: inferior gluteal artery
Identify the encircled arteries
Blue: Uterine artery
Red: Internal pudendal artery
Identify the encircled arteries
Red: Vaginal Artery
Blue: Middle rectal artery (variable positioning)
Identify the encircled arteries
Blue: umbilical artery
Red: obturator artery
Purple: superior vesicle arteries
From superficial to deep, what is the order of these structures: rectum, bladder, uterus
bladder -> uterus -> rectum
