"The coccyx is formed from four rudimentary vertebrae and does not contain a spinal canal, pedicles, laminae or spinous processes. The first segment is the largest, and the subsequent ones are smaller in size. Structure of the coccygeal vertebral junctions is variable and age-related, ranging from fully developed to rudimentary intervertebral discs with varying degrees of cystic or fibrotic change, to fusion of the vertebrae in the later decades."
"type I: present in over half of people; the coccyx has a gentle ventral curvature as a continuation of the natural curvature of the sacrum and a caudally pointing apex"
