pelvic viscera Flashcards
pelvic cavity
fpelvis
what are the 3 bony pelvis parts?
innominates (hip bones, os coxae)
sacrum
coccyx
pelvis
What are the 3 parts of the innominates of pelvis?
ilium
ischium
pubis
label
what is the normal coccyx mobility degree range?
5°-20°
clinical importance
Do all pelvic floor muscles connect into the coccyx?
yes
what does nutation mean?
nodding (as in anterior pelvic tilt)
occurs in sagittal plane
The sacrum moves forward, down, and rotates to the opposite side of the body. This happens when the sacrum absorbs shock.
What does counternutation mean?
moves posteriorly (as in PPT)
occurs in sagittal plane
The sacrum moves backward, up, and rotates to the same side of the body that absorbed the force. The ilium rotates in the opposite direction
there are 2 sacroiliac joints taht are made of what type of cartilage?
hyaline cartilage and fibrocartilage
What type of cartilage is hyaline?
type II collagen and proteoglycans providing a smooth, low friction surface for joints
most common type of cartilage
what type of cartilages is the pubic symphysis composed of?
hyaline cartilge and fibrocartilage
What is fibrocartilage?
thickest fibers, that is the strongest and least flexible of the 3 cartilage types
what is the superior border and inferior border of the pelvic cavity/true pelvis
superior border: pelvic brim/pelvic inlet
inferior border: pelvicdiaphragm (levator ani)
the pelvic cavity is continous with what other cavity?
with abdominal cavity
what is the function of the pelvic inlet?
entrance to the birth canal
what position of the hips is best to widen pelvic outlet?
internal rotation
T/F the coccyx can not be injured during childbirth?
false - it can althought it’s rare
what can occur at the pubic symphysis during delivery?
diastasis (these people are typically non ambulatory right after birth)
What is the difference in the greater pelvis between male and female?
male: deep
female: shallow
what is the shape of the lesser pelvis for male and female?
male: narrow, deep, tapering
female: wide, shallow, cylindrical
what is the pelvic inlet shaped like for male and female?
male: heart shaped, narrow
female: oval or rounded,wide
What is the size of pelvic outlet for male and female?
male: comparatively small
female: comparatively wide
What is the size of pubic arch adn subpubic angle in male and female?
male: narrow
female: wide
The uterus is found typically?
within pelvic cavity and into greater pelvic
where will the uterus expand into with a growing fetus?
abdominal cavity
the uterus is typically found in which position?
anteverted
which ligament helps uterus maintain anteveretd position during pregnancy?
round ligament
what are the 3 parts to the broad ligament?
- mesometrium
- mesosalpinx
- mesovarium
- mesovarium is closes to ovary
- mesometrium is covering uterus
what is the orgin, insertion of round ligament?
origin: uterine cornu of uterus (anterior lateral prtion of uterus)
insertion: runs through inguinal ring and lbends into mons pubis and labia majora
ovarian ligament orgin and insertion?
origin: medial to ovary
insertion: posterolateral aspect of uterus (wrapped in mesovarium)
overian suspensory ligament orgin and insertion?
origin: folds of pelvic parietal peritoneum from over external iliac arteries along pelvic wall
insertion: ovary and broad ligament
uteroscacral ligament orgin and insertion?
origin: base of uterus at the level of the cervix
insertion: anterior border of sacrum
what are 3 signs that endometrial lesions are present?
- chronic sacroiliac joint pain
- worsens with menstrual cycles
- pain with intercourse and bowl movements
What are the 4 parts of the fallopian tubes?
infundibulum
ampulla
isthmus
uterine part
What does the infundibulum contain?
the opening (abdominal ostium) with the fimbriae to encourage oocyte to enter
the sartorius muscle contributes to the formation of?
adductor canal - medial boundry
femoral triangle -lateral boundry
What is the ampulla a common site for?
widest section - therefore common site for fertilization
isthmus is a narrow portion with?
thicker walls as itenters into outerus
uterine part is the portion of the fallopian tubes that?
passes through uterine wall into uterus
is the ovary connected to the fallopian tube?
NO
what is the role of the ovary?
to produce oocytes for fertilization
What production is the ovary responsible for?
estrogen and progesterone production
an oocyte is swept up into fallopian tube via?
fimbriae
what is the pH level of the vagina?
4.2-4.8 - acidic
with age the prostate?
grows - increased and common site for cancer
the internal and external urethral sphincters are located where in relation to the prostate?
IUS: superior to prostate
EUS: inferior to prostate
the gland in the prostate secrete what type of fluid to counteract vaginal canal?
alkaline?
Where does sperm come from?
epididymis via ductus deferens
what gland secretes seminal fluid?
cowpers gland - small glands which open into the urethra at base of penis
what 2 things connect and enter the posterior prostate via ejacultory duct?
ductus deferens and seminal vesicles
the seminal vesicfle releases what type of fluid?
seminal
the internal anal sphincter is made of what type of muscle? it has what type of control?
