### Somatosensory System Study Questions

1. **Identify the four modalities of the somatosensory system.**

2. **Describe the type of receptor (unencapsulated, encapsulated, or specialized epithelial cell), the sensation(s)/modality(ies) transmitted, and the type of adaptation (rapid, slow, or both) for each of the cutaneous receptors listed below.**
   - Meissner corpuscle
   - Pacinian corpuscle
   - Ruffini corpuscle
   - Hair follicle
   - Merkel complex
   - Free nerve ending

3. **Identify the two pathways that carry sensory information for discriminative touch and proprioception.**

4. **Identify the two special sense receptors that are under tonic control.**

5. **Which two special sense pathways have 2° (secondary; second order) afferent neurons that do not travel to the thalamus FIRST?**

### Instructions for Educators:
- **1 & 3**: These questions assess students' knowledge of the fundamental concepts of the somatosensory system and sensory pathways.
- **2**: This question focuses on the specifics of different cutaneous receptors, encouraging students to understand the structure, function, and adaptation mechanisms.
- **4 & 5**: These questions evaluate students’ understanding of sensory receptors and neural pathways, focusing on specialized control and neural routing.
