Components

(generated)

• 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*)
 * [- iliocostalis muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-iliocostalis-muscle): extends and lateral flexes spine
 * [- rotatores muscles] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-rotatores-muscles): facilitates the unilateral rotation and bilateral extension of the spine
 * [- spinalis muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-spinalis-muscle): lateral flexion of spine
* *Trunk back extensors* (*trunk-back-extensors*)
 * [- semispinalis dorsi (thoracis)] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-semispinalis-dorsi-thoracis): extends vertebral column
 * [- interspinales muscles] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-interspinales-muscles): aid in extension and rotation of vertebral column
 * [- intertransversarii muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-intertransversarii-muscle): aid in lateral flexion of vertebral column; acting bilaterally, stabilize vertebral column
 * [- levatores costarum muscles] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-levatores-costarum-muscles): elevate ribs, assisting respiration; assist with lateral flexion of vertebral column}
 * [- longissimus muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-longissimus-muscle): extends spine
 * [- multifidus muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-multifidus-muscle): stabilizes vertebrae in local movements of vertebral column
 * [- quadratus lumborum muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-quadratus-lumborum-muscle): extension of lumbar vertebral column, with bilateral contraction; alone, lateral flexion of vertebral column; together, depression of thoracic rib cage
 * [- semispinalis cervicis] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso 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*)
 * [- external intercostal muscles] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-external-intercostal-muscles): aid in quiet and forced inhalation
 * [- serratus posterior superior muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-serratus-posterior-superior-muscle): elevate the ribs which aids in inspiration
* *Trunk chest extensors* (*trunk-chest-extensors*)
 * [- subcostalis muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-subcostalis-muscle): synergist in aiding the internal intercostal muscles with forced exhalation
 * [- transversus thoracis muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-transversus-thoracis-muscle): depresses the ribs; aids in exertional expiration by decreasing the transverse diameter of the thoracic cage
 * [- internal intercostal muscles] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-internal-intercostal-muscles): aid in forced expiration
 * [- serratus posterior inferior muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-serratus-posterior-inferior-muscle): depress the lower ribs, aiding in expiration

• *Trunk abdomen* (*trunk-abdomen*)

* *Trunk abdomen flexors* (*trunk-abdomen-flexors*)
 * [- rectus abdominis muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso 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
 * [- abdominal internal oblique muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-internal-oblique-muscle): compresses abdomen and rotates vertebral column
 * [- pyramidalis muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-pyramidalis-muscle): tensing the linea alba
 * [- abdominal external oblique muscle] (BrainRegionLPC_SC_VH_PM LPC.SC.VH.PM -> HumanMusclesTorso trunk-abdominal-external-oblique-muscle): rotates torso
* *Trunk abdomen extensors* (*trunk-abdomen-extensors*)
 * [- transversus abdominis muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso trunk-transversus-abdominis): compress the ribs and viscera, providing thoracic and pelvic stability
