Sacrospinalis Group of Muscles 3D

  • Iliocostalis Muscle
    • * Originates from the sacrum (lumborum part), transverse processes of thoracic vertebrae (thoracis part), and transverse processes of cervical vertebrae (cervicis part).
    • * Inserts into the ribs (lumborum part), transverse processes of thoracic vertebrae (thoracis part), and transverse processes of cervical vertebrae (cervicis part).
    • * Receives blood from branches of the posterior intercostal arteries.
    • * Innervated by dorsal rami of spinal nerves.
    • * Is responsible for extending and hyperextending the vertebral column.                                                                                                                                                                                                                                                                                                                                                                                                                              
  • Spinalis Muscle​​​​​​​
    • * Originates from the spinous processes of the upper lumbar and lower thoracic vertebrae (thoracis part), the spinous processes of upper thoracic vertebrae (cervicis part), and the spinous processes of cervical vertebrae (capitis part).
    • * Inserts into the spinous processes of thoracic and cervical vertebrae, reaching the base of the skull (capitis part).
    • * Blood supply is provided by branches of the posterior intercostal arteries.
    • * Innervated by dorsal rami of spinal nerves.
    • * Plays a role in spinal extension and hyperextension, aiding in maintaining the spine's natural curvature and supporting an upright posture.

 

  • Longissimus Muscle​​​​​​​
    • * Originates from the sacrum (lumborum part), transverse processes of thoracic vertebrae (thoracis part), and transverse processes of cervical vertebrae (cervicis part).
    • * Inserts into the ribs (lumborum part), transverse processes of thoracic vertebrae (thoracis part), and transverse processes of cervical vertebrae (cervicis part).
    • * Receives blood from branches of the posterior intercostal arteries.
    • * Innervated by dorsal rami of spinal nerves.
    • * Is responsible for extending and hyperextending the vertebral column.
