SPLENIUS CERVICIS

Have you ever feel pain in your neck or collarbone? So this pain is caused by splenius cervicis muscle as it is located at the posterior side of the neck. They are broad and thin muscles and make one layer of four posterior muscles and make a V shape and lie under the upper trapezius and beneath the rhomboids in their origin. It can also create pain in skull, head and on the top of the head. People who face this pain experienced whiplash trauma or they work for long hours at the desk. There’s no matter how the pain is because it can be cured easily.

These muscles are straighter up than capitis and moves around the neck. Splenius cervicis is a Latin word so Splenius means patch and cervicis means neck, so, its whole meaning is patch located at the head.

 

SPLENIUS CERVICIS

 

Anatomy of Splenius Cervicis:

Origin:

These muscles originate from the spinous processes of the 3rd to the 6th thoracic vertebrate. The spinous procedures are the thin projections of bone that stretch out from the back of the vertebrae. The thoracic vertebrae are the 12 vertebrae that are situated in the mid-and upper-back areas of the spinal section.

Insertion:

It inserts onto the transverse procedures of the 1st through 3rd cervical vertebrate. The transverse procedures are the thin projections of the bone that stretch out transversely from the back of the vertebrate.

Relations:

Splenius Capitis and Splenius Cervici muscles work together as to extend and move the head and neck.

  • Bottom to the serratus posterior, rhomboids and trapezius muscles
  • shallow to erector spinae and bring down semispinalis muscles

Blood supply:

It is supplied from Posterior rami of the intercostal and bottom cervical branch of costocervical trunk arteries.

Function:

It is responsible to rotate head to the same side and for lateral flexion and act in opposition to the Sternocleidomastoid muscle.

 

Splenius cervicis Innervations:

These muscles innervate through lateral branches of lower cervical dorsal rami from the cervical plexus.
