Not only did Galen contribute tremendously to the understanding of  the respiratory system, blood and the circulatory system, but he was also a pioneer in research about the human spine. His dissections and vivisections of animals led to key observations that helped him accurately describe the human spine, spinal cord, and vertebral column. Galen also played a major role in the discoveries of the Central Nervous System. He was also able to describe the nerves that emerge from the spine, which is integral to his research about the nervous system. Galen went on to be the first physician to study what happens when the spinal cord is transected on multiple different levels. He worked with pigs and studied their neuroanatomy by severing different nerves either totally or partially to see how it affected the body. He even dealt with diseases affecting the spinal cord and nerves. Although his work demonstrated inevitable anatomical inaccuracies, his research was integral to the future advances in knowledge about the spinal column, vertebrae, and spinal cord. Galen primarily worked on lower animals, such as pigs, Barbary apes, sheep, and goats. These animals were used for dissections and anatomical studies.
