Female and male reproductive system Flashcards
What is contained within the pelvic cavity?
Ovaries
Uterine tubes
Uterus
Superior part of vagina
What is contained within the perineum?
Inferior part of vagina Perineal muscles Bartholin's glands Clitoris Labia
What are the primary reproductive organs in women?
Ovaries
What is the function of the inferior part of the parietal peritoneum?
Floor of peritoneal cavity
Roof over pelvic organs
What pouches form in the female peritoneum?
Vesico-uterine
Recto-uterine
How can fluid from the pouch of douglas be drained?
Needle passed through the posterior fornix of the vagina
Where will abnormal fluid collect within the peritoneal cavity in women?
Pouch of douglas; most inferior part of the peritoneal cavity in the anatomical position
Are the pelvic organs intra or sub peritoneal?
Sub
What part of the pelvic organs are intraperitoneal?
Uterine tubes
What is the broad ligament and where can it be found?
Double layer of peritoneum
Extends between the uterus and lateral walls + floor of pelvis
What is the function of the broad ligaments and what is contained within it?
Uterine tubes
Proximal part of round ligament
What is the round ligament?
Embryological remnant
Where does the round ligament attach?
Lateral aspect of uterus
Passes through the deep inguinal ring to attach to the superficial tissue of the female perineum
What are the 3 layers of the uterus?
Perimetrium
Myometrium
Endometrium
Where will the oocyte be fertilised?
Ampulla
Where should the zygote implant?
Body of uterus; anywhere else is an ectopic
What holds the uterus in place?
Uterosacral ligaments
Endopelvic fascia
Levator ani
What can result from weakness of the structures that hold the uterus in place?
Uterine prolapse; inferior movement
What is the most common position of the uterus?
Anteverted
Anteflexed
What does anteverted in terms of the uterus mean?
Cervix tipped anteriorly relative to the axis of the vagina
What does antiflexed mean in terms of the uterus?
Uterus tipped anteriorly relative to the axis of the cervix (mass of uterus lies over the bladder)
What is a very normal and common variation of the standard positioning of the uterus?
Retroverted and retroflexed
Is the vagina usually patent?
No; walls tend to be collapsed
What must be sampled in cervical screening?
Squamocolumnar junction (transformation zone)
What is the “salpinx”?
Tube; refers to fallopian tube
Where do the fimbriated ends of the uterine tubes open into?
The peritoneal cavity to act as a means of communication between the genital tract and the peritoneal cavity
What determines patency of fallopian tubes in a HSG (hysterosalpingogram)?
Radiopaque dye spilling out of the end of the uterine tube and into the peritoneal cavity
What size are the ovaries?
Almond shaped and sized in the lateral pelvic cavity
Where do the ovaries develop?
Posterior abdominal wall and they will move onto the lateral wall of the pelvis (round ligament(
What are the 4 fornix of the vagina?
Anterior
Posterior
2 x lateral
What can be felt on a digital vaginal examination ?
Ischial spines - at 4 and 8 o’clock positions
Position of uterus
Palpation of adnexae
What are the adnexae?
Uterine tubes and ovaries
What is the perineum?
Shallow space between pelvic diaphragm and inferior skin of external genitalia
What do the openings of the pelvic floor allow for?
Passage of distal parts of alimentary, renal and reproductive tracts from pelvis to perineum
What are the 2 triangles of the perineum?
Urogenital
Anal
What are the boundaries of the perineum?
Pubic symphysis at top
Coccyx at bottom
Ischial spines laterally
What is the function of the levator ani muscle?
Tonic contraction
Reflexively contracts further during situations of increased intra-abdominal pressure
Weakness can be a factor in the development of prolapse of the pelvic organs
What supplies the levator ani muscle?
Nerve to levator ani; S3,4,5
?? pudendal nerve
What are the perineal muscles supplied by?
Pudendal nerve
Superficial and deep
What is the perineal body?
Bundle of collagenous and elastic tissue into which the perineal muscles attach
What is the function of the perineal body?
Important to pelvic floor strength
Episiotomy act to preserve perineal body
What is the function of bartholin’s gland?
Mucus secretion for lubrication
What type of tissue lies under the perineal muscles?
Erectile tissue
Where does the bed of the breast extend to and from?
Ribs 2-6
Lateral border of sternum to mid-axillary line
Does the breast extend into the axilla?
Yes; axillary tail of spence
What does the breast lie on?
Deep fascia covering pec major and serratus anterior
What is the retromammary space?
Lies between fascia and breast - allows the breast to move independently of the pec muscle
What attaches the breast tissue to the skin?
Suspensory ligaments
What makes up the breast tissue?
Fat
Non lactating lobues; in pregnant/ breast feeding women these become lactating lobules
