Semispinalis Capitis
Semispinalis Capitis (pronunciation: sem-ee-spy-nuh-lis kap-i-tis) is a muscle located within the human body, specifically in the back and neck region.
Etymology
The term 'Semispinalis Capitis' is derived from Latin, where 'semi' means 'half', 'spinalis' refers to 'spine' and 'capitis' means 'head'. Thus, the term can be loosely translated to 'half-spinal head', indicating its location and function.
Anatomy
The Semispinalis Capitis is a part of the Semispinalis group of muscles, which are part of the larger Transversospinales muscle group. It originates from the transverse processes of the upper thoracic vertebrae and the articular processes of the lower cervical vertebrae, and inserts into the occipital bone, between the superior and inferior nuchal lines.
Function
The primary function of the Semispinalis Capitis is to aid in the extension and rotation of the head and neck. It also plays a role in maintaining posture and controlling movements of the head and neck.
