| EPIDERMIS |  | 
      
        | Corneal layer | Bright    images of polygonal anucleated corneocytes (10-30 µm),    grouped in "islands" separated by skin folds (dark areas) | 
      
        | Granular layer | Presence    of 2-4 cell layers (25-35 µm) with dark, central,    and oval-shaped nuclei, surrounded by bright granular cytoplasm | 
      
        | Spinous layer | A    "honeycomb" appearance with smaller cells (15-25 µm) and well-demarcated limits | 
      
        | Basal layer | Group    of bright cells measuring 7-10 µm. At the dermal-epidermal    junction, rings of bright basal cells surrounding a darker central area    represented by the dermal papilla (edged papilla) | 
      
        | DERMIS |  | 
      
        | Papillary dermis | Gray    reticulated fibers with central blood capillaries surrounded by rings of    bright basal cells (edged papillae) | 
      
        | Reticular dermis | Reticulated    pattern (bands of collagen and elastic fibers) |
