Final answer:
The 5 parts of the epidermis from superior to inferior positioning are the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.
Step-by-step explanation:
The 5 parts of the epidermis from superior to inferior positioning are the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.
The five parts of the epidermis in order from superior to inferior positioning are:
- Stratum corneum: the most superficial layer that provides protection against abrasion and dehydration.
- Stratum lucidum: found only in thick skin on the palms and soles, it acts as an additional barrier.
- Stratum granulosum: contains granules that help to form a waterproof barrier.
- Stratum spinosum: consists of several layers of cells with a spiny appearance.
- Stratum basale: the deepest layer where new cells are constantly produced.
