Question Answer
The diaphragms musculature reaches inward to the central tendon and is fixed @ the periphery, it has 3 parts, they areThe sternal part, the costal part and the lumbar part.
The Sternal part of the diaphragms musculature is attached to theXiphoid process
The Costal Part of the diaphragms musculature is attached to theInferior margin of the thoracic cage.
The Lumbar Part of the diaphragms musculature is attached to theRight Crus & Left Crus, via two aponeurotic muscle coverings called the Arcuate Ligaments


Question Answer
4 Surface Landmarks of Anterolateral Wall areUmbilicus, Linea Alba, Iliac Crest & Inguinal Ligament
The Umbilicus’ common name is theBelly button
The Linea Alba is asubQ fibrous band that runs from the xiphoid process to the pubic Symphysis.
The Iliac Crest is thesuperior lateral curvature of the Ilio-sacral joint.
The Inguinal Ligament is the “division line” between what two things?Anterolateral Ab wall & Thigh (Abdominal cavity & the Femoral Region)
The lumbar vertebral column is found in what part of the abdominal wall?Posterior Wall
5 Layers of Anetrolateral WallSkin, Subcutaneous Tissue, Muscles, Extraperitoneal Fat & Parietal Peritoneum
The aponeuroses & fascia for each layer of the anterolateral wall are classified under thisthe Muscles
The structure is made up of the superficial, intermediate and deep layers of the investing fascia and each of three muscle layers that these fascia’s are invested inTransversalis Fascia
Transversalis Fascia is made up ofthe Muscle/Aponeu. of Ext. & Int. Oblique, & Transversus Abdominal Muscle.
The Superficial Fatty Layer of the superficial fascia (the SubQ layer) is calledCamper’s Fascia
The Deep Membranous Layer of the superficial fascia (the SubQ layer) is calledScarpa’s Fascia
The abdominal cavity is lined by theParietal Peritoneum


Question Answer
The 2 layered Flexor Retinaculum of the hip-joint is made bythe Inguinal Ligament & Iliopubic tract.
The lowest part of the External Oblique Aponeurosis is where we’ll find theInguinal Ligament
The Iliopubic tract is found at theinferior margin of the Transversalis Fascia
The nerves and vessels that serve the lower limbs would be found where and with what muscles?Deep to the retinaculum & with the hip flexors
The Inguinal canal carries structures that vary in males and females, what are they?males have spermatic cord & females have the round ligament of the uterus.
What universal structures around found in the inguinal canalblood & lymph vessels and the Ilioinguinal nerve.
What structure(s) make up & add tissue to the deep ring of the inguinal canal?made from transversalis fascia and receives muscle from Internal oblique & cremaster muscle
What structure(s) add tissue to the superficial ring of the inguinal canal & at the superficial ring, where does the inguinal canal pass through?receives aponeurosis from, and passes through, the external oblique aponeurosis.
Hesselbach’s Triangle isThe Rectus Abdominis, Inferior Epigastric Artery & Vein, and Inguinal Ligament
How does a Direct Inguinal Hernia vary from an Indirect Hernia?The abdominal contents that protrude through Hasselbach’s triangle in the Direct Inguinal Hernia is found MEDIAL to the inferior epigastric artery, and for Indirect, the contents protrude LATERAL to the inferior epigastric artery & can follow the inguinal canal to the superficial ring.
If a hernia is found to be MEDIAL to the inferior epigastric artery, then what type is it?Direct
If a hernia is found to be LATERAL to the inferior epigastric artery, then what type is it?Indirect
A Femoral Hernia isthe peritoneum protruding (w/ or w/out abdominopelvic contents) through the femoral canal


Question Answer
The abdominal viscera are suspended in the peritoneal cavity by what? & The viscera are positioned between what two things?Mesenteries; between the cavity and the musculoskeletal wall
Some major neurovascular structures in the abdominal viscera areabdominal aorta, common iliac arteries and veins, inferior vena cava portal vein; lumbosacral plexus
What components of the urinary system (and it’s surrounding structures/organs) are apart of the abdominal viscera?Adrenal Glands, kidneys and Ureters;
What components of the GI system are apart of the Abdominal Viscera?esophagus, stomach, small & large intestines, liver, gallbladder, pancreas & spleen
What Muscles of the posterior abdominal wall are found in the Abdominal Cavity?Psoas Major + Minor, Quadratus Lumborum & Iliacus
What Muscles of the posterior abdominal wall are found in the Pelvic Cavity?Piriformis & Obturator Internus
Which of the posterior abdominal wall muscles allow for flexion of the thigh at the hip joint?Psoas Major, Iliacus
Which of the posterior abdominal wall muscles allow for lateral rotation of extended hip and abduction of flexed hip?Piriformis & Obturator Internus
The Anterolateral Abdominal muscles, going superficial to deep, arethe external & internal abdominal obliques, the Transversus Abdominis & rectus abdominis
Which muscle interdigitates with serratus anterior?External abdominal oblique’s
Which abdominal muscle(s) flex and rotate the trunk?External abdominal oblique & Internal Abdominal Oblique. The Rectus abdominis only flexes.
Which abdominal muscle(s) compresses the abdominal viscera?External abdominal oblique, Internal Abdominal Oblique, Transversus abdominis & Rectus abdominis.
Where does the Anterior and Posterior Rectus Sheaths come together?Linea Alba
Below the Arcuate line we find all of the aponeurosis that we find above the Arcuate line, but what else is there in addition to this, below the Arcuate line in the Anterior rectus sheath?aponeurosis of the Posterior layer of internal abdominal oblique and the transversus abdominis.
What is found above the Arcuate line that isn’t find below the Arcuate line of the posterior rectus sheath?Posterior Layer of the abdominal Oblique aponeurosis and the transversus abdominis aponeurosis. (transversalis fascia is found in both)
