We know the key to passing any course is knowing what to study. But how do you know what to study when you have covered all four major types of tissues, Merkel disks, Meissner corpuscles, Golgi tendon organs, and the composition of the eyes in less than a week? Don't stress. Using a terminology guide will help you understand the meaning of complex Anatomy & Physiology terms. By understanding their meaning your A&P textbook will be less intimidating and tests will be more easily managed.
