Segmental Muscles 3D

  • Interspinales Muscles
    • * Originate from the spinous process of a vertebra.
    • * Insert into the spinous process of the next adjacent vertebra.
    • * Receive their blood supply from segmental arteries from the aorta.
    • * Innervated by dorsal rami of spinal nerves.
    • * Function to extend the spine and provide stability to the back..                                                                                                                                                                                                                                                                                                                                                                                                                            
  • Intertransversarii Muscles​​​​​​​
    • * Originate from the transverse process of a vertebra.
    • * Insert into the transverse process of the next adjacent vertebra.
    • * Receive their blood supply from segmental arteries from the aorta.
    • * Innervated by dorsal rami of spinal nerves.
    • * Control lateral flexion and rotation of the spine and provide stability to the back..

 

  • Levatores Costarum Muscles​​​​​​​
    • * Originate from the transverse process of a vertebra.
    • * Insert into the rib below the origin.
    • * Receive their blood supply from segmental arteries from the aorta.
    • * Innervated by dorsal rami of spinal nerves.
    • * Elevate the rib during inspiration, assist in respiration, and provide stability to the back.
