Every human is composed of an amazing assortment of cells and tissues that carry out myriad functions necessary for sustaining life. In this series of lectures, Professor John K. Young of the Howard University College of Medicine takes audiences through the microscope on a fascinating journey of discovery into the world of cells and tissues, where a complex scheme of activity is taking place all the time, literally just beneath the surface.

In clear, concise language, Professor Young explains the basic categories of cells and tissues and then delves into their specialized functions, whether it be for muscle cells and nervous tissue or the cells of reproductive organs and the highly unusual entities known as "extreme" cells. Finally, Professor Young wraps up the lectures with a topic of universal interest-the death and aging of cells.
