  1. Vertebra

    Each vertebra in a vertebrate’s spinal column is a complex structure composed of bone and some hyaline cartilage, which varies according to the area of backbone and species involved. There are several variations of the basic configuration of a vertebra. Vertebrates take their name from the presence of vertebrae in their vertebral column. A vertebra is classed as an irregular bone. The large part of the vertebra is called its body and the central part of this is called the centrum. The upper and lower surfaces of the body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch and this consists of two pedicles, two laminae and seven processes. The laminae give attachment to the ligamenta flava. There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina allow the entry and exit points for the spinal nerves. The body of the vertebra together with the vertebral arch forms the vertebral foramen, the larger central opening, which accommodates the spinal canal, that houses and protects the spinal cord.
