A&P I Lab - Integration Lab 1 Histology of the Epidermis

The video, presented by Kevin Tokarev, covers the integumentary system, focusing on the skin's structure. It details the epidermis and its layers: stratum corneum, granulosum, spinosum, and basale. The video explains how to identify these layers on microscope slides, emphasizing their staining characteristics. It also distinguishes between thin and thick skin, noting the presence of the stratum lucidum in thick skin areas like the feet and hands. Additionally, the video discusses dermal papillae and their role in forming fingerprints.
