Das Stratum basale – die „Basalzellschicht“ – dient als einlagige innerste Zellschicht der Regeneration der Haut; hier findet die Zellteilung statt. Eine Tochterzelle beginnt ihre Wanderung zur Oberfläche, die andere verbleibt und teilt sich erneut.
What is the stratum germinativum?
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.
What is the function of the stratum granulosum?
The cells of the stratum granulosum (SGR) accumlate dense basophilic keratohyalin granules (seen on the close-up view). These granules contain lipids, which along with the desmosomal connections, help to form a waterproof barrier that functions to prevent fluid loss from the body. Secondly, what is the function of the stratum lucidum?
What is the function of the stratum spinosum?
Answer and Explanation: The main function of the stratum spinosum is to allow keratinocytes to mature. In this layer, they begin to produce their own keratin as well are What are the functions of the stratum corneum?
What are the characteristics of the stratum basale?
Subsequently, question is, what are the characteristics of stratum Basale? The stratum basale is a single layer of columnar or cuboidal basal cells. The cells are attached to each other and to the overlying stratum spinosum cells by desmosomes and hemidesmosomes. The nucleus is large, ovoid and occupies most of the cell.
