2024/2025.
What is the abdominopelvic cavity between?
thoracic diaphragm and pelvic diaphragm
What is the purpose of the dynamic, multilayered, musculo-aponeurotic abdominal walls?
- Contract to increase intra-abdominal pressure
- Capable of distending considerably, accommodating expansions caused by:
Ingestion, Pregnancy, Fat deposition, Pathology
Abdominal Ascites
Increase in fluid within the peritoneal cavity causing abdominal distension.
What is the most common cause of abdominal ascites?
liver disease
What two planes divided the abdominal cavity into four quadrants?
transverse transumbilical plane and the vertical median plane
What is in the right upper quadrant?
liver, gallbladder, duodenum, head of pancreas, right kidney and adrenal, hepatic flexure of colon,
part of ascending and transverse colon
What is in the right lower quadrant?
cecum, appendix, right ovary and tube, right ureter, right spermatic cord
What is in the lower left quadrant?
descending/sigmoid colon
left ovary/duct
left ureter
left spermatic cord
What is in the upper left quadrant?
Liver, stomach, pancreas, left kidney, spleen, and the left adrenal gland
What direction do the fibers of external oblique run?
inferomedially
What two muscles work digastically in the abdomen?
external and internal oblique
Where do the fibers of external and internal oblique decussate?
, linea alba
What actions do the external and internal oblique digastrically in?
the right external oblique and left internal oblique work together when flexing and rotating to bring
the right shoulder toward the left hip (torsional movement of trunk)
What direction do the fibers of internal oblique run?
superomedially
What is the innermost of the three flat abdominal muscles?
transverse abdominis
What direction do the fibers of transverse abdominis run?
horizontal
What is the transverse abdominis oriented the best to accomplish?
compressing the abdomen
What are the characteristics of the linea alba and the rectus sheath?
- Runs vertically the length of the anterior abdominal wall
- Separates the bilateral rectus sheaths
What are the characteristics of the rectus abdominis and the rectus sheath?
- The rectus muscle is anchored transversely by attachment to the anterior layer of the rectus sheath
at three or more tendinous intersections
What is the function of the anterolateral abdominal wall?
-support the abdominal viscera and protect them from most injuries.
- compress the abdominal contents to maintain or increase the intra-abdominal pressure and
oppose the diaphragm - facilitates expulsion
- move the trunk and help to maintain posture
What oblique and transverse muscles do acting together bilaterally?
increases intra-abdominal pressure
What does increased intra-abdominal pressure help to expel air during respiration and more forcibly
for?
- Coughing
- Sneezing
- Nose blowing
- Voluntary eructation (burping)
- Yelling or screaming
Increased intra-abdominal pressure produces the force required for what?
- Defecation (discharge of feces)
- Micturition (urination)
