This quiz on the neural structure will help you when you are studying for your exam in A & P. In Anatomy & Physiology, you will have to know the structure of a neuron and how each structure functions. For instance, as a student you must be familiar with how the axon and dendrites carry electrical signals and how Schwann cells form the myelin sheath of the axon.
This quiz is designed to test your knowledge on this material. In addition, you will want to check out our other Anatomy & Physiology quizzes.
