EM 302 Thin Skin
Hemi-Desmosomes
Grayscale Color
Skin consists o a superficial epithelial component, the epidermis, and underlying connective tissue components, the dermis and hypodermis
Hemi-desmosomes (#1, #2) firmly attach the epidermis to the underlying basal lamina. The hemi-desmosomes themselves are attached to intermediate filaments (i.e., keratin) in the basal layer of cells.
The basal lamina is integrated into the matrix of dermis with many anchoring fibrils.
A small, unmyelinated nerve fiber is seen very close to the epidermis.
