Posterior abdominal muscles Flashcards
The quadratus lumborum is implicated in the formation of which ligaments
the iliolumbar ligament
what is the insertion of the quadratus lumborum
transverse tubercles of the transverse process L1-L4 and 12th rib
what will innervate the quadratus lumborum
the ventral rami of T12, L1-L3 or L4
what is the origin of the psoas major
vertebral bodies T12, L1-L5, S1 and transverse processes of L1-L5
What will innervate the psoas major
primarily the ventral rami of L2 and L3, may include ventral rami of L1 and L4 spinal nerves
What is the origin of the psoas minor
vertebral bodies T12, L1
What will innervate the psoas minor
the ventral ramus of L1 spinal nerve
What will innervate the illiacus
the femoral nerve, primarily the ventral rami of L2 and L3
What is the origin of the levator costarum brevis
transverse tubercles of transverse processes from C7, T1-T11
What will innervate the levator costarum brevis
the dorsal rami of T1-T12 spinal verves
What is the origin of the levator costarum longus
transverse tubercles of transverse processes from T7-T10
What will innervate the levator costarum longus
the dorsal rami of lower thoracic spinal nerves
what will innervate the serratus posterior superior
ventral rami of T2-T5 spinal nerves….intercostal nerves
what is the origin of the serratus posterior inferiro
spinous tubercles of sspinous processes from T11,T12, L1, L2 possibly L3
What will innervate the serratus posterior inferior
ventral rami T9-T11 the intercostal nerves and ventral ramus of T12, the subcostal nerve
