Abdomen: Abdominal Wall Flashcards
What type of hernia is associated with the semilunar line
spigelian hernia
What hernia is associated with the linea alba
umbilical hernia
What type of hernia is associated with the inguinal ligament
inguinal hernia
Where is the semilunar line
between abdominal oblique muscles and rectus abdominus muscles
What are the attachments of the inguinal ligament
ASIS and pubic tubercle
What are the functions of the abdominal wall
support for abdominal organs
movement of trunk
assist respiration
compress abdominal contents
What are the 6 F’s associated with a distended abdomen
fat fluid feces fetus flatus food
How will abdominal pressure change during inspiration and expiration
increase in inspiration, decrease in expiration
What are the two layers of superficial fascia within the abdomen
Campers and Scarpas
What type of fascia is campers fascia
thin, losse fatty layer
What type of fascia is Scarpas fascia
thick, dense layer
What layer will adipose be removed during liposunction
Camper’s fascia
What layer would sutures be placed in on the abdominal wall
Scarpa–thicker to maintain sutures
What spaces are continuous with Scarpa’s fascia
penis and scrotum (dartos)
perineum (colles)
What is Colle’s fascia
superficial perineal fascia
Can fluid from scarpas spread to the thigh
no, not continuous with fascia lata of thigh
How might urine extravasate in a “jumping over the fence” injury
pubic symphysis and fence will smash urethra, tearing it. Blood and urine enter into space of the perineum under colle’s fascia, dartos fascia, shaft of penis under dartos up to abdominal wall
What are the muscles of the abdomen innervated by
T7-T11
What direction are the fibers of the external abdominal oblique
hands in pocket
What direction are the fibers of the internal abdominal oblique
fans out more inferiorly
What direction are the fibers of the trasversus abdominus
completely horizontal
What will compose the anterior and posterior rectus sheath when above the arcuate line
Anterior: aponeurosis of EAO and part of IAO
Posterior: aponeurosis of IAO and TA
What composes the anterior and posterior rectus sheath when below the arcuate line
ANterior: no posterior rectus sheath. All three aponeuroses infront
What nerves come off T1-T11

What are the spinal cord levels for Subcostal
T12
What are the spinal cord levels for Ilioinguinal and iliohypogastric
L1
What is the main anastomosis within the abdominal wall
superior epigastric and inferior epigastric
What veins are responsible for draining the lateral aspect of the abdominal wall
lateral thoracic
superficial epigastric
How might the veins of the abdominal wall be used to compensate for a blockage in the IVC
superficial epigastric and lateral thoracic to drain
What is caput medusae
varicose enlargement of periumbilical veins of the abdominal wall due to portal hypertension
