Female Reproductive Anatomy Flashcards

1
Q

What provides structural support for the female breast?

A

The stroma between the mammary glands forms a network of ligaments (Cooper’s ligaments), that function to keep the breast in its position between ribs 2-6 on the anterior chest wall.

Q

Describe the blood supply to the breast.

A

Medially: branches from the internal thoracic artery.
Laterally: branches from the lateral thoracic artery (a branch from the axillary artery).

Q

Describe the lymphatic drainage of the breast.

A

Medial 25%: parasternal lymph nodes. Due to communication with opposite breast — source of met. to opp. breast.
Lateral 75% (including nipple area): axillary lymph nodes - first, the pectoral nodes. Any mets will be found here first.

Q

Caution must be observed when ligating the lateral thoracic artery (for mastectomy) such that you do not also capture this nerve:

A

Long thoracic nerve. Could lead to winged scapula.

Q

What vascular structure is responsible for filling the clitoris with blood in states of arousal?

A

Deep artery to the clitoris. Analogous structure in males that serves same function.
Dorsal artery just supplies blood to skin and subcutaneous tissue.

Q

What is the name of the double layered flap of parietal peritoneum that wraps around the bladder and uterus forming a mesentery? List its 3 distinct divisions and their structural relations.

A

Broad ligament
Mesosalpinx: between uterine tube and base of mesovarium.
Mesovarium: connects ovary to the uterus, horizontally.
Mesometrium: attached to lateral surface of uterus and is the largest section. Looks like a wing.

Q

Describe the relationship of the uterine artery to the ureter.

A

Water (ureter) under the bridge (uterine artery). Easy to damage ureter when making surgical approach to uterus, e.g. ligating uterine artery.

Q

Describe the differences between 1st, 2nd, and 3rd degree uterine prolapse.

A

1st- cervix just protrudes a little further into the upper portion of the vagina.
2nd- cervix/uterus protrude significantly into the vagina.
3rd- cervix and uterus have exited the opening of the vagina.

Q

Describe the structure carrying the ovarian vasculature and nervous structures to the ovary.

Gubernaculum

17
Q

List 3 visceral herniations that can make intercourse painful for the female, as they are impinging on the vaginal space.

A

Enterocele- small bowel
Rectocele- rectum
Cystocele- bladder

18
Q

List 4 fistulae that can be the result of embryonic malformation, trauma, etc. that connect abnormally with the vagina from other luminal organs.

A

Urethrovaginal - urethra
Vesicovaginal- bladder
Rectovaginal- rectum
