Question

a needle would pierce the epidermal layers of the forearm in which order?
granulosum, basale, spinosum, corneum
basale, spinosum, granulosum, corneum
corneum, granulosum, spinosum, basale
basale, spinosum, granulosum, lucidum, corneum

Explanation:

The epidermis has several layers. The outermost layer is the stratum corneum. Moving inward, the next layers are stratum granulosum, stratum spinosum, and the innermost layer is stratum basale. So a needle piercing from the outside (surface) would go through corneum first, then granulosum, then spinosum, then basale.

Answer:

corneum, granulosum, spinosum, basale (the third option in the given choices).
