An introductory overview for this topic. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
Neuroanatomy is a branch of anatomy and neuroscience that studies the structure and organization of the nervous system. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems. Their neuroanatomy is therefore better understood. In vertebrates, the nervous system is segregated into the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the connecting nerves between them. Much of what has informed neuroscientists has come from observing how lesions (damage) to specific brain areas affects behavior or other neural functions.

How this connects to MD Anatomy
Nervous-system function depends on localized pathways and distributed networks. The timing, distribution and combination of sensory, motor, cognitive or autonomic findings inform localization, while structural imaging, electrophysiology and the clinical examination provide different forms of evidence.

What the underlying subject studies
At postgraduate and higher-specialty level, begin with normal anatomy and physiology of the relevant organ system, then compare distinct disease mechanisms, their evidence base and the limitations of available investigations.
How mechanisms and evidence connect
Advanced study requires evidence appraisal, multidisciplinary interpretation and a clear distinction between established facts, hypotheses and research findings. Procedural, diagnostic and prescribing skills must be learned under an accredited program.
How to develop a sound explanation
Identify the scope of this topic within the named specialty, connect it to the applicable patient population and formulate a structured question that can be answered using current specialty literature and supervised teaching.
