Which layer lies directly above the Stratum Basale?

Explanation:
The layer directly above the basal layer is the Stratum Spinosum. This is the prickle cell layer where keratinocytes start to mature and are held together by numerous desmosomes, giving them a characteristic spiny appearance in prepared slides. The basal layer is the one that continuously divides to replenish the epidermis, and as cells rise, they move into the Spinosum, then progress to the Granulosum, and so on (with Lucidum appearing only in thick skin before the outermost Corneum). So, the Spinosum sits immediately atop the Basale.
