A human's spine has more movement than that of most mammals
Spine. Stick.
The thoracic spine has the most vertebrae - twelve.
Compression fractures are most common along the spine involving the vertebrae. This is when a bone in the spine collapses and is most commonly found in the thoracic area of the spine.
The thoracic spine, where movement of the spinal column is most limited.
A disk herniation most often occurs in the lower back (lumbar spine) or the neck (cervical spine). These are the areas of the spine that experience the most movement and stress, making them more susceptible to injury.
The spine, or spinal column, is made up of a series of joints called gliding joints and are made of dense irregular connective tissue which is strong and allows for only slight movement in comparison to freely movable joints, like those in the arms and legs.

Without a spine, you cannot stand upright.
Most spinal injuries occur in the cervical (neck) and lumbar (lower back) regions of the spine. The cervical spine is particularly vulnerable due to its mobility and range of motion, while the lumbar spine bears a lot of weight and can be prone to injury from lifting or twisting motions.
The most well developed scientific area at the beginning of the academic-discipline movement was
The cervical and lumbar regions of the human spine are enlarged to provide support and flexibility for the head and torso, as these areas bear the most weight and movement in the body.
