Q

What is a pelvic adhesion?

A

adhesion is a band of scar tissue that binds 2 parts of your tissue that aren’t normally joined together.
Pelvic adhesions may involve any organ within the pelvis, such as the uterus, ovaries, fallopian tubes, or bladder, and usually occur after surgery.

Q

What is uterine prolapse?

A

A uterine prolapse is when the uterus descends toward or into the vagina. It happens when the pelvic floor muscles and ligaments become weak and are no longer able to support the uterus. In some cases, the uterus can protrude from the vaginal opening.

Q

What does the gubernaculum do?

A

Function during development.
As the scrotum and labia majora form in males and females respectively, the gubernaculum aids in the descent of the gonads (both testes and ovaries). The testes descend to a greater degree than the ovaries and ultimately pass through the inguinal canal.

26
What does the ovarian ligament do?
Connect: ovary to lateral uterus
27
How does the broad ligament form?
broad ligament forms after the Mullerian ducts join together during development. During this process, 2 layers of peritoneum join together enveloping the pelvic organs, which is then known as the broad ligament.
28

What is the cardinal ligament?
cervix to pelvic side wall
32
What does the cardinal ligament contain?
uterine vessels (from anterior branch of internal iliac) -> supply uterus
33
What happens if you do hysterectomy and you affect the cardinal ligament?
ligate uterine vessels -> ureter at risk (damaged = hydronephrosis)
34
What is the uterosacral ligament?
connect uterus to sacrum
35
What does the infundibulopelvic ligament connect?
ovary to lateral pelvic wall
36
What does the infundibulopelvic ligament contain?
. Contain: ovarian vessels i. In oophorectomy -> ligate vessels -> prevent bleeding i. Ligate ovarian vessels -> ureter courses retroperitoneally -> injury risk
37
What parts does the cervix have?
supra vaginal and intra vaginal
38
What is the external OS clinically used for?
smear test
39
What is the cervical opening into the vagina and why is a doctor familiar with it?

41
What structure links closely to the uterine artery?

42
What is the clinical significance between ureter and uterine artery crossing?
Important in hysterectomy in the operation, uterine artery needs to be ligated to prevent excess blood loss be careful not to ligate ureter too
43
What is the nerve supply of the uterus and at which spinal level do the afferent nerves enter?
sympathetic nerve fibres of the uterus = arise from the uterovaginal plexus. Parasympathetic fibres of the uterus = pelvic splanchnic nerves (S2-S4). The afferent fibres mostly ascend through the inferior hypogastric plexus to enter the spinal cord via T10-T12 and L1 nerve fibres.
44
What is the course of the round ligament?
originate at uterine horns, in the parametrium. round ligament exits pelvis via the deep inguinal ring passes through the inguinal canal continues on to the labia majora its fibers spread and mix with the tissue of the mons pubis.

What is the male equivalent to round and ovarian ligaments?
scrotal ligament

54
What are the grades for uterine prolapse?
Grade 1: uterus may drop slightly and remain above the introitus Grade 2: uterus drops further so that the cervix or lower portion of the uterus reach the region of the introitus Grade 3: cervix or even the entire uterus bulges out of the introitus Grade 4: drops completely out

58
What are the symptoms of endometriosis?
``` Pelvic pain- worse during period period pain that prevents normal activities pain during/after sex pain when peeing or pooing feeling sick constipation diarrhoea blood in pee during period difficulty getting pregnant ```
59
Why does endometrial carcinoma incidence increase?
more obesity HRT diff reproductive trends- less children, have children later
60
What is an adnexa?
Structures between the uterus & pelvic side wall: fallopian tubes, ovaries, and ligaments
61
How do you palpate an adnexal mass?

How long is the uterine tube?
10cm to 13cm
65
What are the 4 parts of the uterine tube?
isthmus ampulla infundibulum fimbraie
66
Where does fertilisation take place?
ampulla
67
Which is the narrowest?
isthmus
68
What type of cells are in the oviduct (tube) and what is the function?
ciliated columnar epithelium | move the egg
69
What can happen in the fallopian tube that is a medical emergency?
ectopic preggo
70
What is the blood supply of the fallopian tube?
medial 2/3rd of tube= UTERINE ARTERY | lateral 1/3rd of tube= OVARIAN ARTERY

84
What is the course of the ovarian vessels?
``` The ovarian (or testicular) arteries arise from the abdominal aorta pass downward and laterally on the anterior surface of psoas major. They continue to descend and as they cross the pelvic inlet they travel in the suspensory ligament of the ovary. The arterial supply must travel a long course because, just like the testes, the ovaries develop high on the posterior abdominal wall and then descend before birth, bringing with them their vessels, lymphatics and nerves ```

keep germs out
