Due to the similarities between these two terms, they are often confused to mean the same even though there are a number of differences between them. A job title provides a more clear idea of what an employee does to earn a living and the operations he performs. Occupation on the other hand gives an insight into the industry the employee works in.
Layers of the Skin. The Epidermis. The epidermis is the outermost layer of the skin, and protects the body from the environment. The thickness of the epidermis varies in different types of skin; it is only .05 mm thick on the eyelids, and is 1.5 mm thick on the palms and the soles of the feet.
Epidermis, the epithelial layer of skin, is primarily protective. This layer, consisting of keratinized stratified squamous epithelium, is tough, relatively impermeable, and self-replacing. These functional qualities are conferred by the epidermis' principal cell type, the keratinocyte. Although the stratum spinosum is permeable to water, the epidermis becomes relatively impermeable in the stratum granulosum and stratum corneum. 2  Damage to extensive areas of epidermis, e.g. by burns, renders the skin highly permeable and constitutes a medical emergency.
