Splenius Muscle

Anatomy

 

Origin:

  • Splenius Capitis

    • Spinous processes of thoracic vertebrae T3-T6, cervical vertebrae C7 & the lower half of ligamentum nuchae (posterior neck ligaments)
  • Splenius Cervicis

    • Spinous processes of throacic vertebrae T3-T6

Insertion:

  • Splenius Capitis

    • Mastoid process of temporal & occipital bones (skull)

  • Splenius Cervicis

    • Transverse processes of vertebrae C1-C3



Major Arteries:

  • Transverse cervical artery (Spenius Cervicis)

  • Occipital artery (Spenius Cervicis)

 

Neural Innervation:

  • Posterior rami of the lower cervical spinal nerves
