Understanding neurology starts with the brain’s anatomy and how it controls every function of the body. In this lesson, we’ll review the roles of the medulla, occipital lobe, and parietal lobe, as well as the brainstem and cerebrospinal fluid circulation. You’ll also learn the structure and function of neurons — from the cell body and myelin sheath to the axon terminals that transmit signals — giving you the foundation to understand both normal brain function and the impact of injury.
