Which skin layer is several cell layers thick; its cells contain cytoplasmic processes, but the processes are lost as the cells ascend toward the surface of the skin?

This layer is characterized by several layers of living keratinocytes that stay interconnected. The cells here extend cytoplasmic processes that reach out to neighboring cells and are held together by desmosomes, giving a distinctive spiny or stellate appearance under the microscope. As the keratinocytes mature and migrate toward the surface, these cytoplasmic extensions diminish and the cells flatten as they progress toward the superficial, more keratinized strata. This combination of multiple cell layers, with cells that have cytoplasmic processes forming intercellular connections that are lost as they ascend, is the hallmark of the stratum spinosum.
