### Final Answer
The major branches of a spinal nerve are called **rami**.

### Explanation
In the anatomy of the spinal cord, spinal nerves split into branches known as rami. Each spinal nerve divides into a dorsal ramus and a ventral ramus, each responsible for different functions and areas of the body. The term "roots" refers to the initial segments of the nerve that emerge from the spinal cord, while "rootlets" are smaller branches that make up the roots. "Plexus" refers to a network of nerves, not major branches. Therefore, the correct choice is rami.
