Where the fat is deposited and accumulates within the hypodermis depends on hormones (testosterone, estrogen, insulin, glucagon, leptin, and others), as well as genetic factors. This stored fat can serve as an energy reserve, insulate the body to prevent heat loss, and act as a cushion to protect underlying structures from trauma. Adipose tissue present in the hypodermis consists of fat-storing cells called adipocytes. The hypodermis is home to most of the fat that concerns people when they are trying to keep their weight under control. Fingerprints are unique to each individual and are used for forensic analyses because the patterns do not change with the growth and aging processes. In a growing fetus, fingerprints form where the cells of the stratum basale meet the papillae of the underlying dermal layer (papillary layer), resulting in the formation of the ridges on your fingers that you recognize as fingerprints.

Melanin gives hair and skin its color, and also helps protect the living cells of the epidermis from ultraviolet (UV) radiation damage. The second is a melanocyte, a cell that produces the pigment melanin. These cells are especially abundant on the surfaces of the hands and feet. The first is a Merkel cell, which functions as a receptor and is responsible for stimulating sensory nerves that the brain perceives as touch. Two other cell types are found dispersed among the basal cells in the stratum basale. As new cells are formed, the existing cells are pushed superficially away from the stratum basale. All of the keratinocytes are produced from this single layer of cells, which are constantly going through mitosis to produce new cells. A basal cell is a cuboidal-shaped stem cell that is a precursor of the keratinocytes of the epidermis. The stratum basale is a single layer of cells primarily made of basal cells. The epidermis of thick skin has five layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
