Chapter 5, Problem 3ILQ
Figure 5.6 If you zoom on the cells of the stratum spinosum, what is distinctive about them?
Figure 5.6 Cells of the Epidermis The cells in the different layers of the epidermis originate from basal cells located in the stratum basale, yet the cells of each layer are distinctively different. EM × 2700. (Micrograph provided by the Regents of University of Michigan Medical School © 2012)
