Place the classic stages in the clinical progression of generalized tetanus in the correct chronological order, from initial exposure to advanced presentation.

Trismus is identified as commonly appearing first. Rigidity and spasms are central manifestations, and sensory stimuli may trigger the spasms. The material does not specify a precise universal timeline beyond trismus commonly appearing first, so this ordering reflects the teaching sequence rather than an invariant clinical progression. **Key takeaway:** Trismus is the early clue; stimulus-triggered spasms are a notable feature.\n\n**Glossary:** **Sensory stimulus**: an input such as sound, touch, or light.
