Solution

The cell bodies of lower motor neurons for the upper limb are located in the anterior (ventral) horn of the spinal cord. Specifically, they are found in the lateral part of the anterior horn in the cervical spinal cord segments C5-T1. These neurons are also known as alpha motor neurons. They send their axons out of the spinal cord via the ventral root, and these axons travel through peripheral nerves to reach the muscles of the upper limb.
