Skin Structure and Function Assessment

This video, part of the University of Rochester series, is presented by Mary Thayer and focuses on the histology of skin tissue. It covers the structure of the skin, detailing the epidermis, dermis, and hypodermis layers. The epidermis is described with its specific layers: stratum basale, spinosum, granulosum, lucidum, and corneum. The video explains the function and composition of each layer, highlighting the unique features of thick skin found on palms and soles. The dermis is discussed as a fibrous and elastic layer containing collagen and elastin, while the hypodermis is noted for its adipose tissue. The video concludes with a summary of these key points.
