There is only one spinal cord in the human body. The human spinal column is made up of 33 bones - 7 vertebrae in the cervical region, 12 in the thoracic region, 5 in the lumbar region, 5 in the sacral region and 4 in the coccygeal region
In a child:
7 Cervical, 12 Thoracic, 5 Lumber, 5 Sacral and 3-5 Coccygeal vertebrae.... therefore 32-34
In an adult, the sacral and coccygeal vertebrae are fused to form the sacrum and coccyx, therefore adults have:
7 Cervical, 12 Thoracic, 5 Lumbar vertebrae.... therefore 24, plus a sacrum and coccyx

The spinal cord is protected by the vertebrae.
The spinal cord is a bundle of nerve fibers which is inside of the vertebrae (backbones).

in the spinal canal between the vertebrae.
The spinal cord is protected by the vertebral column or spinal column. The vertebral column is a collection of individual bones called vertebrae that encase and protect the spinal cord. The vertebral column is divided into three parts: seven cervical (neck) vertebrae at the top, twelve thoracic vertebrae in the midback, and five lumbar vertebrae in the lower back. Below the lumbar vertebrae, but not protecting the spinal cord, are the sacrum and coccyx (tailbone).
