This comprehensive overview explores the intricate structure and function of the nervous system, including the central nervous system (CNS), peripheral nervous system (PNS), cranial and spinal nerves, and autonomic control. Key aspects of brain anatomy such as the cerebrum, brainstem, thalamus, and meninges are examined. Additionally, we delve into common neurological pathologies including gliomas, meningitis, Parkinson’s disease, and Alzheimer’s, highlighting their impact on health and treatment options. Gain insights into the complexities of afferent and efferent pathways, as well as somatic and autonomic responses.
