The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
Retrocollis is the extension of the neck (head tilts back) and uses the following muscles for movement: bilateral splenius, bilateral upper trapezius, bilateral deep posterior paravertebrals. This is the "chin-in-the-air" version. A combination of these head positions is common; many patients experience turning and tilting actions of the head. [10]

The neck is the part of the body in many vertebrates that connects the head to the torso. It supports the weight of the head and protects the nerves that transmit sensory and motor information between the brain and the rest of the body. Additionally, the neck is highly flexible, allowing the head to turn and move in all directions.
The splenius capitis (/ ˈ s p l iː n i ə s ˈ k æ p ɪ t ɪ s /) (from Greek splēníon 'bandage' and Latin caput 'head' [1] [2]) is a broad, straplike muscle in the back of the neck. It pulls on the base of the skull from the vertebrae in the neck and upper thorax. It is involved in movements such as shaking the head.
