Stratum lucidum (location...description) between stratum corneum and stratum granulosum on soles and palms; cells applear clear; nuclei, organelles and cell membrane are no longer visible Stratum granulosum (location...description) It can only be found in those regions of the body where the skin is particularly thick, such as the palms or the soles. Medical definition of stratum granulosum: a layer of granular nondividing cells lying immediately above the stratum basale in most parts of the epidermis. The presence of a stratum granulosum in C. vellerosus neonates and its reduction in more advanced ontogenetic stages, in direct relationship with cornified scale development, supports the hypothesis that the partial parakeratosis in the xenarthran integument is secondary, as in other eutherians, and can be interpreted as a derived character state.Fil: Krmpotic, Cecilia Mariana. It consists of cells that have recently died and been moved into the epidermis.

Function: Protection from UV light, sunlight, chemical, and regulation of body temperature. Stratum Spinosum or the Spiny layer. Functional tight junction barrier localizes in the second layer of the stratum granulosum of human epidermis. 2. Layers of the epidermis: The epidermis is made up of 95% keratinocytes but also contains melanocytes, Langerhans cells, Merkel cells, and inflammatory cells.The stratum basale is primarily made up of basal keratinocyte cells, which can be considered the stem cells of the epidermis. F inally, the stratum corneum is composed of dead cells filled with keratin. Viral inclusions have been noted in nuclei of cells in the stratum granulosum of warts, with scattered viral particles in stratum spinosum nuclei and extracellular aggregates in surface keratin debris. Stratum Spinosum and Granulosum. Stratum Granulosum The cells in the stratum granulosum, or granular layer, have lost their nuclei and appear as flattened cells containing dark clumps of cytoplasmic material. Stratum lucidum: It only exists in the thick skin (soles, palms etc. Stratum granulosum: It contains more keratinocytes that synthesize a colourless protein (keratin). The function of the stratum corneum is to protect the skin against abrasion, dehydration, and pathogen invasion. Stratum granulosum and stratum lucidum. The stratum basale (also called the stratum germinativum) is the deepest epidermal layer and attaches the epidermis to the basal lamina, below which lie the layers of the dermis.The cells in the stratum basale bond to the dermis via intertwining collagen fibers, referred to as the basement membrane. The protruding structures called desmosomes are responsible for the shiny appearance of stratum spinosum. Stratum lucidum Location. Like its name suggests, the stratum spinosum contains spiny protrusions that hold the cells tightly together to prevent your skin from tearing and blistering. The granule cell layer (stratum granulosum) is the next layer (3-5 layers of cells).As the cells move up into this layer, they start to lose their nuclei and cytoplasmic organelles, and turn into the keratinised squames of the next layer. Description: the hair covering of an animal or a body part: the coating of hairs on a human head. These layers from deep to superficial are stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. Location of melanocytes and tactile epithelial cells. The stratum granulosum is a layer of the human skin. This layer gives the epidermis its strength. It can be found between the two other epidermal layers – Stratum granulosum and Stratum corneum. The stratum granulosum has a grainy appearance due to further changes to the keratinocytes as they move up from the stratum spinosum. Stratum Basale. Their spiny (Latin, spinosum) appearance is due to shrinking of the microfilaments between desmosomes that occurs when stained with H&E.
