| In great detail the differences are laid out between the male and female skull, spine, clavicle, sternum, coccyx, and pelvis. |
| The pelvic girdle horizontally flanks the coccyx, the bony rod at the posterior end of the vertebral column. |
| The Seatstrap should be pushed down as far as possible towards the coccyx, and it then helps to lift under the buttocks during raising. |
| The lowest lumbar vertebra articulates with the sacrum, and this in turn with the coccyx. |
| The spine is made up of 24 bones called vertebrae, plus the sacrum and coccyx. |
| The spinal column is composed of seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae, the bony sacrum, and the coccyx. |
