An elementary nervous system, or nerve net, allows jellyfish to smell, detect light, and respond to other stimuli.
Jellyfish have an ectoderm (outside skin layer) and endoderm (inside skin layer), but no mesoderm to hold their organs like we do. Instead, inside is the very spinelessness of the jellyfish, a gelatinous stuffing called mesoglea.
