What are the boundaries of the abdominal cavity?
superior: diaphragm
inferior: pelvic diaphragm (imaginary plane at pelvic inlet)
what are the boundaries of the anterolateral abdominal cavity?
superior: 7-10 Costal cartilages
inferior: inguinal ligament/pelvis
walls: muscle/aponeurosis
What two planes make up the horizontal lines in the 9 part division of the abdomen? What spinal level?
transpyloric (L1)
transtubercular (L5)
What are the superior 3 divisions in the 9 grid?
right/left hypochondriac, epigastric in middle
what are the 3 middle divisons of the 9 grid?
right/left flank, umbilical
what are the 3 inferior divisions of the 9 grid?
right/left inguinal, suprapubic

What organs are located in the RLQ? (9)
appendix cecum ascending colon ilium right ovary right ureter right spermatic cord uterus bladder
what organs are located in the LUQ? (8)
body/fundus of stomach spleen left lobe of liver jejunum pancreas body/tail left kidney transverse colon descending colon
what organs are located in the LLQ?
sigmoid colon descending colon left ovary left ureter bladder uterus left spermatic cord
What spinal level is the transpyloric plane? what organs are at this level?
L1
-pylorus, duodenum, gallbladder, root of transverse mesocolon, hepatic portal vein, neck of pancreas
What spinal level is the subcostal plane? organs?
L3
- transverse colon
- 2,3 parts of duodenum
What spinal level is the transtubercular plane? organs?
L5
iliocecal junction
what spinal level is the interspinous plane? organs?

appendix
From superficial to deep what are the layers of the anterior abdominal wall?
skin campers fascia (Fat) scarpas fascia external oblique internal oblique transversus abdominis transversalis fascia depending on where you are: rectus abdominis
why can fluid not flow from superficial abdomen to leg?
scarpas fascia fuses with fascia lata of lower limb
What is the innervation, origin, insertion, function of the external oblique?
inn: anterior rami of T7-T12
origin: serratus anterior ribs
insertion: linea alba
function: compress abdomen, rotate, retain posture
What is the innervation, origin, insertion, function of the internal oblique?
inn: T7-L1, iliohypogastric, ilioinguinal
origin: iliac crest
insertion: lina alba
function: compress/lateral flexion
What is the innervation, origin, insertion, function of the transversus abdominis?
inn: T7-L1, iliohypogastric, ilioinguinal
linea alba, lower ribs who cares
compresses
What is the innervation, origin, insertion, function of the rectus?
inn T7-T12
flex abdomen, f
what are some features of the external oblique? 2
fibers run like hands in your pockets
lower part rolled to make inguinal ligament
features of internal oblique? 2
makes conjoin tendon with TA
fibers make cremaster muscle
features of trasnversus abdominis? 1
contributes to conjoin tendon
what role do abdominal muscles play in respiration?
active exhalation
