The neck muscle of the neck (m. Splenius cervicis) begins on the spinous processes of III-IV thoracic vertebrae. It is attached to the posterior tubercles of the transverse processes of two or three upper cervical vertebrae. The muscle covers the back of the beginning of the muscle bundles raising the scapula. Behind her is a trapezius muscle.
Function of the neck muscle: with simultaneous (on both sides) contraction of the muscle, the cervical part of the spine is unbent. With one-sided contraction, the muscle turns the cervical part of the spine in its direction.
Innervation of the neck muscle: back nerves of the spinal nerves (CIII-CIII).
Blood supply to the neck muscle: occipital artery, deep neck artery.
