The numbers 1 to 5 in the left indicates 5 layers as mentioned earlier. This single layer of cells is firmly attached to the basal lamina, which separates the epidermis from the loose connective tissue of the adjacent dermis. . The stratum spinosum (or spinous layer/prickle cell layer) is a layer of the epidermis found between the stratum granulosum and stratum basale. stratum basa´le the deepest layer of the epidermis , composed of a single layer of basophilic cells. Some of the dividing cells move up to the next layer. Gratis Vokabeltrainer, Verbtabellen, Aussprachefunktion. The basal cell layer (stratum basale, or stratum germinosum), is a single layer of cells, closest to the dermis. Melanocytes produce the skin coloring or pigment known as melanin, which gives skin its tan or brown color and helps protect the deeper layers of the skin from the harmful effects of the sun. The amount of melanin produced though predetermined genetically, is affected by sun exposure levels leading to increase or decrease in … Rapidly . The top layer of the skin is the epidermis which is divided into four layers: the stratum corneum, stratum granulosum, stratum spinosum, and stratum basale.
