The spine is divided into regions with different structural characteristics: the cervical, thoracic, lumbar, sacral, and coccygeal regions. The thoracic region has rib attachments, providing stability and limiting movement, while the cervical and lumbar regions are more flexible and designed for greater mobility. The intervertebral discs and the orientation of the facet joints also contribute to the varying degrees of flexibility throughout the spine. Consequently, some parts can bend more easily, while others are more rigid for support.
Spine. Bone, not muscle.
An asymmetrical contraction of the erector spinae muscles can result in lateral flexion of the spine, where the spine bends to one side.
Unfortunately, I don't know the answer, but a physical therapist told me this is true of me. The muscles on the right side of my spine are more developed. I have a mild (approx. 12 degree Cobb angle) dextroscoliosis (bends to the right like a backwards C) of the cervical spine and levoscoliosis (bends to the left like a C) of the superior thoracic spine. One spine/pain MD told me the two might be related.
"Dextrocurvature of cervical spine" refers to a curvature of the cervical spine towards the right side. The cervical spine is composed of seven vertebrae (C1 to C7) in the neck region. Normally, the spine should have a gentle curve known as lordosis when viewed from the side. Dextrocurvature indicates that this natural curve bends towards the right side of the body, possibly due to various reasons such as muscle imbalances, postural habits, or underlying spinal conditions.
Curvature convexity of the spine refers to the direction in which the spine curves. A spine with a convex curvature means that the curve of the spine protrudes outward, while a concave curvature means the curve of the spine bends inward. It's important to monitor spinal curvature as abnormal curvatures can lead to various health issues.
The spine is a part of the endoskeleton.

You turn tiny by the age for example: If you're 91 your spine bends and you get more tiny. There you have it that is how youy get more tiny.
No, it is part if the intestines.
The spine is composed of the vertebrae. This is part of the skeletal system. The spinal cord is part of the nervous system.
