|January 1, 1975
Summary
Scanning electron microscopy confirmed human nail structure. The hard dorsal nail plate is supported by the flexible intermediate nail plate.
Area of Science:
- Dermatology
- Histology
- Biomaterials Science
Background:
- Human nail anatomy is complex and crucial for digital protection and function.
- Previous studies have described nail plate composition but detailed structural relationships require further SEM investigation.
Purpose of the Study:
- To utilize scanning electron microscopy (SEM) to visualize and confirm the structural organization of normal human nail plates.
- To elucidate the relationship between the dorsal and intermediate nail plate layers.
Main Methods:
- Human nail samples were prepared by sectioning.
- Cut surfaces were examined using scanning electron microscopy (SEM) to analyze nail plate microstructure.
Main Results:
- SEM imaging clearly delineated distinct layers within the human nail plate.
- The hard dorsal nail plate was observed to be structurally supported by the underlying, more pliable intermediate nail plate.
Conclusions:
- The study confirms the layered structure of the human nail plate.
- SEM provides valuable high-resolution insights into the mechanical support system of the nail, with the dorsal plate resting upon the intermediate plate.
