A stratum (pl. strata) is a layer. Therefore in the context of the skin, a stratum is a layer of skin. (The skin is also known as the "integument", or "integumentary system".)
A stratum (of skin) is a layer of tissue or layer/s of cells.
- the stratum corneum,
- the stratum lucidum,
- the stratum granulosum,
- the stratum germinativum,
(which is also known as the “Malpighian Layer”),
- the stratum spinosum and
- the stratum basale.
To view the location of a stratum of skin relative to other parts of the skin see the diagram of the structure of the skin. This may be of particular interest to students of courses in massage, reflexology, beauty therapies, and other health science or clinical courses.
