Components

Component items:

• Trunk sensory data (trunk-sensory-data)
  • Trunk - upper somatic receptors (trunk-upper-somatic-receptors -> LPC.PN.SG.UDRG): somatic sensation from skin of upper region
  • Trunk - lower somatic receptors (trunk-lower-somatic-receptors -> LPC.PN.SG.LDRG): somatic sensation from skin of lower abdomen and lateral side of gluteal region
• Trunk back (trunk-back)
  • Trunk back flexors (trunk-back-flexors)
    • Trunk - iliocostalis muscle (LPC.SC.VH.PM -> trunk-iliocostalis-muscle): extends and lateral flexes spine
    • Trunk - rotatores muscles (LPC.SC.VH.PM -> trunk-rotatores-muscles): facilitates the unilateral rotation and bilateral extension of the spine
    • Trunk - spinalis muscle (LPC.SC.VH.PM -> trunk-spinalis-muscle): lateral flexion of spine
  • Trunk back extensors (trunk-back-extensors)
    • Trunk - semispinalis dorsi (thoracis) (LPC.SC.VH.VM -> trunk-semispinalis-dorsi-thoracis): extends vertebral column
    • Trunk - interspinales muscles (LPC.SC.VH.VM -> trunk-interspinales-muscles): aid in extension and rotation of vertebral column
    • Trunk - intertransversarii muscle (LPC.SC.VH.VM -> trunk-intertransversarii-muscle): aid in lateral flexion of vertebral column; acting bilaterally, stabilize vertebral column
    • Trunk - levatores costarum muscles (LPC.SC.VH.VM -> trunk-levatores-costarum-muscles): elevate ribs, assisting respiration; assist with lateral flexion of vertebral column}
    • Trunk - longissimus muscle (LPC.SC.VH.VM -> trunk-longissimus-muscle): extends spine
    • Trunk - multifidus muscle (LPC.SC.VH.VM -> trunk-multifidus-muscle): stabilizes vertebrae in local movements of vertebral column
    • Trunk - quadratus lumborum muscle (LPC.SC.VH.PM -> trunk-quadratus-lumborum-muscle): extension of lumbar vertebral column, with bilateral contraction; alone, lateral flexion of vertebral column; together, depression of thoracic rib cage
    • Trunk - semispinalis cervicis (LPC.SC.VH.PM -> trunk-semispinalis-cervicis-muscle): extends and rotates the head to the contralateral side and also extends the ribs
• Trunk chest (trunk-chest)
  • Trunk chest flexors (trunk-chest-flexors)
    • Trunk - external intercostal muscles (LPC.SC.VH.PM -> trunk-external-intercostal-muscles): aid in quiet and forced inhalation
    • Trunk - serratus posterior superior muscle (LPC.SC.VH.PM -> trunk-serratus-posterior-superior-muscle): elevate the ribs which aids in inspiration
  • Trunk chest extensors (trunk-chest-extensors)
    • Trunk - subcostalis muscle (LPC.SC.VH.VM -> trunk-subcostalis-muscle): synergist in aiding the internal intercostal muscles with forced exhalation
    • Trunk - transversus thoracis muscle (LPC.SC.VH.VM -> trunk-transversus-thoracis-muscle): depresses the ribs; aids in exertional expiration by decreasing the transverse diameter of the thoracic cage
    • Trunk - internal intercostal muscles (LPC.SC.VH.VM -> trunk-internal-intercostal-muscles): aid in forced expiration
    • Trunk - serratus posterior inferior muscle (LPC.SC.VH.VM -> trunk-serratus-posterior-inferior-muscle): depress the lower ribs, aiding in expiration
• Trunk abdomen (trunk-abdomen)
  • Trunk abdomen flexors (trunk-abdomen-flexors)
    • Trunk - rectus abdominis muscle (LPC.SC.VH.PM -> trunk-rectus-abdominis-muscle): flexion of trunk/lumbar vertebrae; keeping the internal organs intact and in creating intra-abdominal pressure, such as when exercising or lifting heavy weights
    • Trunk - abdominal internal oblique muscle (LPC.SC.VH.PM -> trunk-internal-oblique-muscle): compresses abdomen and rotates vertebral column
    • Trunk - pyramidalis muscle (LPC.SC.VH.PM -> trunk-pyramidalis-muscle): tensing the linea alba
    • Trunk - abdominal external oblique muscle (LPC.SC.VH.PM -> trunk-abdominal-external-oblique-muscle): rotates torso
  • Trunk abdomen extensors (trunk-abdomen-extensors)
    • Trunk - transversus abdominis muscle (LPC.SC.VH.VM -> trunk-transversus-abdominis): compress the ribs and viscera, providing thoracic and pelvic stability
