The parasympathetic levels of the uterus are provided by which nerves?

Explanation:
The parasympathetic supply to the uterus comes from the sacral outflow—pelvic splanchnic nerves arising from spinal levels S2 to S4. These preganglionic fibers travel with the pelvic nerves into the pelvic (uterine) plexus and synapse on postganglionic neurons near the uterus, providing the parasympathetic input to the organ. This is why the other options don’t fit: lumbar and thoracic splanchnics carry sympathetic fibers, not parasympathetic, and the relevant parasympathetic pathways to pelvic organs specifically come from S2–S4.
