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.

Diagram showing the organization of the autonomic nervous system, with labeled pathways for parasympathetic and sympathetic nerves, highlighting synapses, neurotransmitters like acetylcholine and norepinephrine, and their receptor types.
