abdomen, diaphragm, & pelvic cavity :) Flashcards
(;.;)
Intercostals Actions (external and internal)
- externals: draw ribs superiorly to help with inhalation
-internal: draw ribs inferiorly to help with exhalation
intercostals origin
inferior border of rib above
intercostals insertion
superior border of rib below
psoas major purpose
hip hike, ascending stairs
psoas major origin
sides of T12-L5, TP 1-5
psoas major insertion
lesser trochanter of femur
psoas major MA
insertion FIXED
insertion: hip flexion and hip lateral rotation
**hip stabilization!!!
psoas major MA
origin fixed
WITH ORIGIN FIXED * anterior pelvic tilt * and trunk flexion with thigh
***hip stabilization!!
psoas major nerve
anterior rami of 1,2,3
iliacus purpose
climb a ladder, cycling
iliacus SA
sacrum, anterior sacroiliac ligament, iliac fossa
iliacus IA
lesser trochanter and psoas tendon
iliacus MA
- thigh flexion and hip stabilization …acts with psoas major
diaphragm purpose
singing, playing trumpet
diaphragm MA
draw down the central tendon of diaphragm to increase thoracic cavity space during inhalation
diaphragm origin
sternal attachment: inner xyphoid process
costal attachment: upper surfaces of ribs 1-6
lumbar attachment: LV 1-3
diaphragm insertion
central tendon
diaphragm nerve
C3,4,5 keep u alive….PHRENIC NERVE!!
what 3 structures pass through the diaphragm and what are their levels?
inferior vena cava - t8
esophagus and vagus nerve - t10
aorta & thoracic duct - t12
