1. Ruffini Corpuscle → Stretching (C)
Function
- Detects:
- Skin stretch
- Sustained deformation
- Joint movement
Characteristics
- Slowly adapting receptor
- Located in:
- Deep dermis
- Joint capsules
Clinical Importance
Helps in:
- Finger position sense
- Grip modulation
2. Merkel Cells → Sustained Pressure (B)
Function
- Detect:
- Sustained pressure
- Texture
- Form discrimination
Characteristics
- Slowly adapting
- Small receptive field
- Important for fine tactile discrimination
Location
- Basal epidermis
Example
Reading Braille
3. Pacinian Corpuscle → Vibration (A)
Function
- Detects:
- Deep pressure
- High-frequency vibration
Characteristics
- Rapidly adapting
- Onion-like lamellar structure
- Very sensitive to vibration
Location
- Deep dermis
- Subcutaneous tissue
4. Meissner’s Corpuscle → Fine Touch (D)
Function
- Detects:
- Fine touch
- Flutter
- Low-frequency vibration
Characteristics
- Rapidly adapting
- Small receptive field
Location
- Glabrous (hairless) skin:
- Fingertips
- Lips
- Palms
