Content includes why we need to know about the nervous system and a simple summary of what we need to know about the structure and function of the nervous system. Broader connections and continuities are introduced, along with information about neurons (cell bodies, axons) and glial cells (support cells for neurons). Neurotransmitters (the chemical communication) and what influences these are discussed. Nerve anatomy and physiology is covered, along with what nerves need to function well. We look at structural and functional neuroplasticity and the nervous system on Trager—it’s more than you might think!
