Q
For the external genitalia, name:
- Blood supply
- Sensory innervation
- Lymphatic drainage
A
- blood supply: internal pudendal artery
- sensory innervation: pudendal nerve
- lymphatic drainage: inguinal nodes

Q
Describe: Vagina (3)
A
- muscular canal extending from cervix to vulva, anterior to rectum and posterior to bladder
- lined by rugated, stratified squamous epithelium
- upper vagina separated by cervix into anterior, posterior, and lateral fornices
5
Q
Describe blood supply of vagina (1)
A
vaginal branch of internal pudendal artery with anastamoses from uterine, inferior vesical, and middle rectal arteries
6
Q
Describ: Uterus (2)
A
- thick walled, muscular organ between bladder and rectum, consisting of two major parts:
- uterine corpus
- cervix
- supported by the pelvic diaphragm, the pelvic organs, and 4 paired sets of ligaments
7
Q
What’s the blood supply of uterine corpus? (1)
A
uterine artery (branch of the internal iliac artery, anterior division)
8
Q
What’s the blood supply of cervix? (1)
A
cervical branch of uterine artery
9
Q
Name ligaments of uterus (4)
A
- round ligaments
- uterosacral ligaments
- cardinal ligaments
- broad ligaments
10
Q
Describe: Round ligaments (3)
A
- travel from anterior surface of uterus, through broad ligaments, and inguinal canals then terminate in the labia majora
- function: anteversion
- blood supply: Sampson’s artery (branch of uterine artery running through round ligament)
11
Q
Describe: Uterosacral ligaments (2)
A
- arise from sacral fascia and insert into posterior inferior uterus
- function: mechanical support for uterus, prevent prolapse and contain autonomic nerve fibres
12
Q
Describe: cardinal ligaments (2)
A
- extend from lateral pelvic walls and insert into lateral cervix and vagina
- function: mechanical support, prevent prolapse
13
Q
Describe: broad ligaments (2)
A
- pass from lateral pelvic wall to sides of uterus;
- contain fallopian tube, round ligament, ovarian ligament, nerves, vessels, and lymphatics
14
Q
Describe: Infundibulopelvic ligament (3)
A
- (suspensory ligament of the ovary)
- continuous tissue that connects ovary to pelvic wall
- contains the ovarian artery, ovarian vein, ovarian plexus, and lymphatic vessels
15
Q
Name possible position of the uterus (3)
A
- anteverted (majority)
- retroverted
- neutral
