Within both the pelvic cavity and the perineum
What parts of the female reproductive system lie in the pelvic cavity?
Ovaries
Uterine / Fallopian tubes
Uterus
Superior part of vagina
What parts of the female reproductive system are found in the perineum?
Inferior part of vagina
Perineal muscles
Bartholin’s glands
Clitoris
Labia
Label this image
Describe the peritoneum in the female
Inferior part of parietal peritoneum - forms floor of peritoneal cavity and roof over pelvic organs
Covers the superior aspect organs
What pouches are found in females?
Vesico-uterine pouch (utero-vesico)
Recto-uterine pouch (pouch of Douglas)
Label these pouches found in females
Label this image
What is the broad ligament of the uterus?
Double layer of peritoneum
Extends between the uterus and the lateral walls and floor of pelvis
What does the broad ligament of the uterus do?
Helps maintain the uterus in its correct midline position
What does the broad ligament of the uterus contain?
The fallopian(uterine) tubes and the proximal part of the round ligament
Label this
Label this
What is the round ligament of the uterus?
An embryological remnant
Attaches to lateral aspect of the uterus
Proximal part is contained within broad ligament
Where does the round ligament of the uterus pass through?
The deep inguinal ring to attach to the superficial tissue of the female perineum
Label this
Label this
What are the 3 layers of the body of the uterus?
Perimetrium
Myometrium
Endometrium
Why is the body of the uterus important?
Implantation of zygote occurs in body of uterus
If implantation occurs anywhere but the body of the uterus, its called a ?
Ectopic pregnancy
Label this
Label this
Fallopian tube (uterine tube)
What is the most common position of the uterus?
Anteverted and anteflexed
Describe what anteflxed and anteverted means in terms of the most common position of the uterus
What is the normal variation of the position of the uterus?
The uterus is held in position by 3 levels of support, which are?
Number of strong ligaments (e.g. uterosacral ligaments)
Endopelvic fascia
Muscles of pelvic floor (e.g. levator ani)
Label this
Where does fertilisation occur?
In the ampulla of the fallopian (uterine) tube
Usually do not lie symmetrically
What is “salpinx” the greek word for?
tube
What is a bilateral salpingo-oophrectomy?
Removal of both Fallopian tubes and ovaries
What is a unilateral salpingectomy?
Removal of one of the fallopian tubes
Label this
Where does the fimbriated end of the Fallopian tubes open into?
the peritoneal cavity - communication between the genital tract and the peritoneal cavity
Thus, in theory, infection could pass between these two areas
What kind of scan is this?
Where are ovaries located and what size are they?
Almond sized and shaped - located laterally in the pelvic cavity
Where do the ovaries develop?
On posterior abdominal wall and move onto the lateral wall of the pelvis (the round ligament of the uterus)
Ovaries secrete what hormones?
Oestrogen and progesterone in response to anterior pituitary hormones FSH and LH
What is the vagina?
A muscular tube whose walls are normally in contact, except superiorly where the cervix holds them apart forming a fornix (space around the cervix)
A fornix has 4 parts which are?
Anterior
Posterior
2x lateral
Label this
The walls of the vagina are usually?
Collapsed
The clinician must be able to see what in order to perform a cervical screening procedure?
Cervix
What must be sampled in cervical screening procedure?
Squamo columnar junction (transformation zone)
How is a cervical screening procedure performed?
Brush is inserted into the external cervical os with firm pressure and rotated
During a vaginal digital examination, what can be palpated?
Position of the uterus - assessed by bimanual palpation
What does palpation of the adnexae involve?
Uterine tubes and ovaries
Can detect large masses or tenderness affecting these structures
What kind of a muscle is the levator ani muscle?
Skeletal muscle (voluntary control)
What forms the majority of the pelvic diaphragm, with its fascial coverings?
Levator ani muscle
What does the levator ani muscle do?
Provides continual support for the pelvic organs
Tonic contraction
Reflexively contracts further during situations of increased intra-abdominal pressure
What is the levator ani muscle supplied by?
Nerve to levator ani (S3,4,5 sacral plexus)
dual supply?
What is the perineum?
Shallow space between pelvic diaphragm and skin
The perineum is divided into?
Superficial and deep pouches
What are the openings in the pelvic floor?
passage of distal parts of
alimentary, renal and reproductive tracts from pelvis to perineum
Label this
What are the perineal muscles?
Superficial and deep
What nerve supplies the perineal muscles?
Pudendal nerve
What is the perineal body?
bundle of collagenous and elastic tissue
into which the perineal muscles attach
Why is the perineal body important?
Important to pelvic floor strength
Can be disrupted during labour
Where is the perineal body?
Located just deep to skin
Label this
Label this
Where is the bed of breast?
from ribs 2-6
Lateral border of sternum to mid-axillary line
What does the female breast lie on?
On deep fascia covering pectorals major and serrates anterior
What space lies between fascia and breast?
Retromammary space
The female breast firmly attaches to skin via?
Suspensory ligaments
Label this
If a lump in the breast is felt, how do we describe its position and how do we assess it?
If a lump in the breast is felt, what others areas should also be assessed?
Axilla
Supraclavicular area
Label this
Most lymph (>75%) from the breast drains into?
Ipsilateral axillary lymph nodes and then into supraclavicular nodes
Lymph from inner breast quadrants can drain to?
The parasternal lymph nodes
Lymph from lower inner breast quadrant can drain to?
Abdominal lymph nodes
Lymph from the upper limb drains to?
The axillary lymph nodes
What is contained in the axilla and what is it all embedded in?
- brachial plexus branches
- axillary artery (& branches) and axillary vein (& tributaries)
- axillary lymph nodes
- all embedded in axillary fat
Describe level 1, II and III axillary node clearance
Level I – inferior and lateral to pectoralis minor
- Level II – deep to pectoralis minor
- Level III – superior and medial to pectoralis minor
What is the blood supply and drainage to the breast?
