Consists of several parts of the vertebra, namely the cervical vertebra, thoracic vertebra, lumbar vertebra, sacrum and caudal

Neural canal

Each vertebra has an opening known as the neural canal

Spinal cord

Long, thin, tubular structure made up of nervous tissue located in the neural canal

Similarity between vertebrae
