No. Both nerve cord and spinal cord are different from each other.
The nerve cord is a hollow tube of nervous tissue and is an important structure of the central nervous system. In chordates, the dorsal nerve cord is present in the embryonic stage that develops into the brain and spinal cord. Invertebrates such as earthworms and insects have the nerve cord which is present along the body length.
The spinal cord is a tube-like structure, which consists of bundles of nerve fibres and acts as pathways for communication between the brain and the body.
