Anatomy of Sensory Tract and Motor Tract

A 43-year-old man came with complaints of not being able to feel pain and moving his body parts. After examination, complaints were felt from the abdomen at the level of the navel (periumbilical area) to the tips of the toes. The periumbilical area is innervated by which sensory dermatome?
