transverse abdominus | a-compress abdominal contents o-lateral inguinal ligament, iliac crest, thoracolumbar aponeurosis, internal surface of last six ribs i-abdominal aponeurosis to linea alba |
rectus abdominus | a-flex vertebral column o-pubic sympysis, pubic crest i-cartilage of ribs 5, 6,7 and xyphoid process |
external oblique | a-uni-flex v.column to same side, rotate to opposite side bi-flex vertebral column, compress abdominal contents o-lower 8 ribs i-anterior part of iliac crest, abdominal aponeurosis to linea alba |
internal obilque | a-uni flex v.c to same side, rotate to same side bi-flex vc, compress abdominal contents o-lateral inguinal ligament, iliac crest, thoracolumbar facia i-internal surface of lower 3 ribs, abdominal aponeurosis to linea alba |
psoas major | a-flex hip, adduction, lat rotate reverse-anterior pevic tilt, rotate lumbar vert to opposite side, laterally flex vertbrae to same side o-tp of T12-L5, lateral aspect of bodies of T12-L5, and disks b/t T12-L5 i-lesser trochanter of femur |
iliacus | a-flex hip, adduct hip, lat rotate reverse-anterior pevlic tilt o-internal iliac fossa i-lesser trochanter of femur |
diaphragm | a-draw central tendon down, increase volume of thoracic cavity to assist inspiration o-costal-internal surface of lower 6 ribs sternal-inner part of xyphoid process lumbar-upper 2 or 3 lumbar vertebrae i-central tendon |
intercostals | a-ext-draw ribs up & out inspiration int-draw ribs inferiorly during exhalation o-inferior border of rib above i-superior border of rib below |
splenius capitis | a-extend h/n, lat flex h.n to same side, rotate h/n to same side o-sp of C7-T3, lower part of nuchal ligament i-mastoid process of temporal bone, lateral part of superior nuchal line |
splenuis cervicis | a-extend h/n, lat flex h/n to same side, rotate h/n to same side o-sp of T3-T6 i-tp of C1-C3 |
serratus posterior superior | a-elevate ribs during inhalation o-spinous process of C7-T3 i-posterior surface of ribs 2-5 |
serratus posterior inferior | a-depress ribs during exhalation o-sp of T12-L3 i-posterior surface of ribs 9-12 |
muscles of breathing | diaphragm, external intercostals, scalenes, sternocleidomastoid, serratus posterior superior, pec minor, pec major, serratus anterior expiration:diaphragm, int intercost, abdominals, serr post inf |
erector spinae group | iliocostalis, longissimus, spinalis |
thoracolumbar aponeurosis | o-posterior sacrum, iliac crest, sp of T11&T12, sp of L1-L5 |
spinalis | goes from sp to sp extends from L2-C2 good at extending spine, not rotating or flexing |
longissimus | has 3 sections goes from sacrum & posterior iliac crest to C2 and mastoid process extends, lat flex v.c to same side, rotates to same side thickest of es group |
iliocostalis | goes from sacrum & medial iliac crest to lower rib angles, lower rib angles to upper rib angles & tp of C7, upper rib angles to tp of C4-C6 strongest to perform lateral flexion |
transversospinalis group | originate of tp and insert of sp of vert above semispinalis-span 3-6 most vertical multifidi-span 2-4 rotatores-span 1-2 most horizontal |
semispinalis | extends from T10-occiput attaches to vertebrae except C1 thickest, strongest extender of v.c and head |
multifidi | extend from sacrum and medial iliac crest to sp of C2 very thick on posterior aspect of sacrum good at extending and rotating |
rotatores | goes from upper sacrum to sp of C2 good at rotating to opposite side thickest at thoracic spine |
transversospinalis group | semispinalis-thickest at neck multifidi-thickest at sacrum rotatores-thickest at thoracic a-extend v.c, lat flex to same side, rotate to opposite side |
quadratus lumborum | a-laterally flex v.c to same side, assists extension of v.c, hip hiker-lifts posterior iliac crest, fixes ribs in forced inhalation and exhalation o-iliolumbar ligament, iliac crest i-12th rib, tp of L1-L4 |
