In my field, human anatomy and physiology (A&P), like many others, it is customary to end each textbook chapter with a concept review and self-testing exercises. For the first five editions of my Anatomy & Physiology—The Unity of Form and Function, I titled my end-of-chapter feature “Chapter Review” and its first section, “Review of Key Concepts.” I followed the traditional practice of summarizing the chapter in short declarative sentences like these:
- Microvilli are short surface extensions of the plasma membrane that increase a cell’s surface area. They are especially well developed on absorptive cells, as in the kidney and small intestine. On some cells, they play a sensory role.
- Parathyroid hormone is secreted by the parathyroid glands in response to hypocalcemia. It raises blood Ca2+ levels by indirectly stimulating osteoclasts, inhibiting osteoblasts, promoting calcitriol synthesis, and promoting Ca2+ conservation by the kidneys.
Recently, we’ve seen shifts from print to digital, the rise of open educational resources and open-access journals, the consolidation of large publishers into mega-publishers, fundamental changes in how authors are compensated, and other significant changes to the nature of authoring. As we wait to see which of the ripples coming over the horizon dissipate and which become large—perhaps overwhelming—waves, what can we authors do to remain afloat?
