Diagram of a human figure showing the full nervous system, including the brain, spinal cord, and branching peripheral nerves throughout the body, with labels for each part.

Diagram of the autonomic nervous system showing the sympathetic and parasympathetic divisions. The left side illustrates sympathetic nerves branching from the spinal cord to organs and glands, while the right side shows parasympathetic nerves connecting to organs such as the eye, heart, lungs, liver, stomach, intestines, and bladder. Color-coded pathways and labeled ganglia highlight the different nerve routes and target organs in human anatomy.
