Stratum spinosum

This electron micrograph shows the upper portion of the stratum spinosum, the stratum granulosum and the stratum corneum.   Also visible is a Langerhans cell, a dendritic macrophage functioning in local immune responses.  Small to medium keratohyalin granules are visible in the stratum granulosum just beneath the stratum corneum.  4000x
