4. Doing sit-ups

  • Internal Oblique - Action(Compresses abdomen and flexes vertebral column), Innervation(Thoracic spinal nerves T-8-T12, iliohypogastric and ilioinguinal nerve)

  • Rectus femoris - Action(extend leg and flex thigh at hip joint), Innervation (Femoral nerve)

6. Breathing

  • Diaphragm - Action(Contraction of diaphragm which leads to inhalation and relaxation of diaphragm which causes exhalation), Innervation( Phrenic nerve)
  • External intercostals - Action( contraction elevates ribs that leads to inhalation, relaxation depresses ribs that leads to exhalation), Innervation(Thoracic spinal nerves T2-T12)
  • Internal intercostals - Action(Contraction draws adjacent ribs together), Innervation(Thoracic spinal nerves T2-T12)
