The spinal nerves arise from the spinal column. 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.
In human anatomy, the rhomboid minor is a small skeletal muscle of the back that connects the scapula to the vertebrae of the spinal column. [1] It arises from the nuchal ligament, and the 7th cervical and 1st thoracic vertebrae and intervening supraspinous ligaments; it inserts onto the medial border of the scapula.
Occipito-cervical junction This disorder may result from rheumatoid arthritis, causing the hypermobility of the connection between the neck and head, resulting in paralysis or pain. [6] Cerebrovascular disease Cerebrovascular disease is a type of cervical spine disorder that can cause tetraplegia. [7] Subaxial cervical spine [8] Atlanto-axial joint
It arises by a series of small tendons from the transverse processes of the sixth to the tenth thoracic vertebrae, and is inserted, by tendons, into the spinous processes of the upper four thoracic and lower two cervical vertebrae. The semispinalis muscles are innervated by the dorsal rami of the cervical spinal nerves.
In humans, cervical vertebrae are the smallest of the true vertebrae and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery, vertebral veins, and inferior cervical ganglion pass. The remainder of this article focuses upon ...
Neck pain, although felt in the neck, can be caused by numerous other spinal problems. Neck pain may arise due to muscular tightness in both the neck and upper back, or pinching of the nerves emanating from the cervical vertebrae. Joint disruption in the neck creates pain, as does joint disruption in the upper back.

The rhomboid muscles (/ ˈ r ɒ m b ɔɪ d /), often simply called the rhomboids, are rhombus-shaped muscles associated with the scapula.There are two rhomboid muscles on each side of the upper back: [1] [2] [3]
