Semispinalis cervicis
Semispinalis Cervicis
Semispinalis cervicis (pronunciation: sem-ee-spy-nuh-lis ser-vi-sis) is a muscle located in the human body's posterior neck and upper back region. It is part of the Semispinalis group of muscles, which are part of the larger Erector Spinae muscle group.
Etymology
The term "Semispinalis" is derived from the Latin words "semi", meaning half, and "spinalis", referring to the spine. "Cervicis" is also Latin, referring to the neck. Thus, the term "Semispinalis cervicis" can be translated as "half-spinal muscle of the neck".
Anatomy
The Semispinalis cervicis originates from the transverse processes of the upper thoracic vertebrae (T1-T6) and inserts into the spinous processes of the cervical vertebrae (C2-C5). It functions to extend and rotate the cervical spine.
