The first three strata of the epidermis consists of <u>living </u>keratinocytes and the most superficial strata contain dead keratinocytes.
<h3>
What is the role of the keratinocytes?</h3>
Keratinocytes are the most common cell type in the epidermis, the outermost layer of the skin, accounting for over 90% of all cells. They begin in the epidermis's deepest layer, the stratum basale, and progress to the skin's last barrier layer, the stratum corneum.
The stratum basale (germinatum) is the innermost (deepest) layer of the epidermis, followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and the stratum corneum, which is the outermost layer.

Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
Cell is the basic unit of life while organs are the group of tissues formed from cells.
One example is the neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions.
Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions.
