* 
- *posterior ramus, motor*; MODALITY={flexor motor, extensor motor}
* 
* *motor nerves of back, extensors*; DISTRIBUTION={longissimus muscle, multifidus muscle, semispinalis, levatores costarum muscles, interspinales muscles, intertransversarii muscle}; MODALITY={extensor motor}; MUSCLES={[- interspinales muscles] - aid in extension and rotation of vertebral column; [Trunk - intertransversarii muscle] - aid in lateral flexion of vertebral column; acting bilaterally, stabilize vertebral column; [Trunk - levatores costarum muscles] - elevate ribs, assisting respiration; assist with lateral flexion of vertebral column; [Trunk - longissimus muscle] - extends spine; [Trunk - multifidus muscle] - stabilizes vertebrae in local movements of vertebral column; [Trunk - semispinalis cervicis] - extends and rotates the head to the contralateral side and also extends the ribs; [Trunk - semispinalis dorsi (thoracis)] - extends vertebral column}; FIBERS={GSE:BrainRegionLPC_SC_VH_VM Ventromedial Nucleus,LPC.SC.VH.VM -> BrainRegionTARGET_TEA_TRUNK Trunk,TARGET.TEA.TRUNK}
* *motor nerves of back, flexors*; DISTRIBUTION={iliocostalis muscle, spinalis muscle, rotatores muscles}; MODALITY={flexor motor}; MUSCLES={[- iliocostalis muscle] - extends and lateral flexes spine; [Trunk - rotatores muscles] - facilitates the unilateral rotation and bilateral extension of the spine; [Trunk - spinalis muscle] - lateral flexion of spine}; FIBERS={GSE:BrainRegionLPC_SC_VH_PM Posteromedial Nucleus,LPC.SC.VH.PM -> BrainRegionTARGET_TEA_TRUNK Trunk,TARGET.TEA.TRUNK}
* 
- *thoracic and abdominal intercostal nerves*; MODALITY={flexor motor, extensor motor}
* 
* *thoracic and thoracicoabdominal intercostal nerves, flexors*; DISTRIBUTION={rectus abdominis; external intercostal muscles; serratus posterior superior muscle}; MODALITY={flexor motor}; MUSCLES={[- sternalis muscle] - protract and stabilize scapula, assists in upward rotation; [Trunk - abdominal external oblique muscle] - rotates torso; [Trunk - external intercostal muscles] - aid in quiet and forced inhalation; [Trunk - rectus abdominis muscle] - flexion of trunk/lumbar vertebrae; [Trunk - serratus posterior superior muscle] - elevate the ribs which aids in inspiration}; FIBERS={GSE:BrainRegionLPC_SC_VH_PM Posteromedial Nucleus,LPC.SC.VH.PM -> BrainRegionTARGET_TEA_TRUNK Trunk,TARGET.TEA.TRUNK}

* *thoracicoabdominal intercostal nerves, extensors*; ORIGIN={T7-T11}; DISTRIBUTION={internal intercostal muscles, serratus posterior inferior}; MODALITY={extensor motor}; MUSCLES={[- internal intercostal muscles] - aid in forced expiration; [Trunk - serratus posterior inferior muscle] - depress the lower ribs, aiding in expiration; [Trunk - subcostalis muscle] - synergist in aiding the internal intercostal muscles with forced exhalation; [Trunk - transversus abdominis muscle] - compress the ribs and viscera, providing thoracic and pelvic stability; [Trunk - transversus thoracis muscle] - depresses the ribs; aids in exertional expiration by decreasing the transverse diameter of the thoracic cage}; FIBERS={GSE:BrainRegionLPC_SC_VH_VM Ventromedial Nucleus,LPC.SC.VH.VM -> BrainRegionTARGET_TEA_TRUNK Trunk,TARGET.TEA.TRUNK}
