I have found myself consistently emailing my professor with questions because Marieb skips out on detail. I have also been consulting my gray's anatomy textbook because this textbook lacks the structures I need to study in lab. At times the author will list components, and either summarize them with a single sentence, or just list them with no elaboration.
-For instance, when discussing cells found in connective tissue the book says "masts cells and macrophages are so important to overall body defense that they deserve brief mention here" and lists three chemicals found in mast cells, with a single sentence describing each chemical. If mast cells are so important, why not follow this up with a brief explanation of *how these three chemicals work together*? What is most incredible that this section of text is IDENTICAL to the FOURTH EDITION with NO FURTHER ELABORATION! Why jump through four new editions without revising the book to offer better content? -Another fine example of lack of elaboration is found in the section describing the ultrastructure and molecular composition of myofilaments. I quote, "Other proteins that act to bind filaments or sarcomeres together and maintain their alignment include nebulin, myomesin, and C proteins." The text then cuts to a section titled "Sarcoplasmic Reticulum and T-Tubules" and fails to provide any other information surrounding these compounds.
I think the Tortora A&P textbook does a better job of presenting a complete picture of the human body that is appropriate for the undergrad level, giving more detailed explanations, as well as providing more examples of homeostasis vs dysfunction. It presents many more clinically relevant facts to bring about further insight and interest within the reader. The images are equal if not superior to Marieb's. I will be selling my copy of Marieb's and sticking with Tortora for the second semester of A&P. I don't have the time or money to waste jumping from book to book. A well written text like Tortora does not assume "They'll learn that in X class."
