Description[edit | edit source]
The posterior muscles of the neck are divided into four layers. The semispinalis capitis and cervicis muscles lie within the third layer[1]. The semispinalis capitis is a long slender muscle which provided a long moment arm to provide efficient extension.
Origin[edit | edit source]
The muscle originates on the articular processes of the C 5, 6, 7 and 8 as well as the transverse processes of T 1, 2 ,3 ,4 ,5 and 6.
Insertion[edit | edit source]
The semispinalis capitis attaches onto the occiput inbetween the superior and inferior nuchal line.
Nerve Supply[edit | edit source]
Greater occipital nerve, which additionally innervates the scalp[2].
Blood Supply[edit | edit source]
Deep cervical artery.
Action[edit | edit source]
Extension of the neck. When one sided, it produces extension and minimal lateral flexion.
Function[edit | edit source]
During bilateral contraction this muscle is considered as a prime mover for dynamically maintaining the cervical lordosis[3]. It is also considered as one of the main factors in maintaining the balance of the head on the neck[4]
