Summary of Introduction to Skin Anatomy and Physiology

00:00:00 - 00:05:00

The skin is the largest organ in the body and is made up of two layers: the epidermis and the dermis. The epidermis is further divided into other layers, including the basement membrane, stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The dermis contains many cells, including fibroblasts, mussels, and sensory nerve fibers. The skin has many important functions, including acting as a barrier against infection and trauma, regulating body temperature, and producing anti-microbial substances.

• 00:00:00 The skin is made up of two layers, the epidermis on the top and the dermis below it. The epidermis can be further divided into other layers, including the basement membrane, stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The dermis contains many cells, including fibroblasts, mussels, and sensory nerve fibers. The dermis also contains artery and vein, and the stratum basale and stratum spinosum can receive blood supply. The top layer of the epidermis, the stratum corneum, is also home to bacteria.
