Class 12 Biology — Human Nervous System (Anatomy & Physiology) Comprehensive Review

A highly scannable framework covering the entire Human Nervous System by Newton Rain. This module breaks down cellular architectures (neuron configurations, Nissl granules, and Schwann cell vs. oligodendrocyte myelination rules), the step-by-step biophysics of impulse propagation (resting potential to action potential shifts), embryonic brain divisions, and cerebral lobe localizations. Includes memorable mnemonics for memorizing all 12 pairs of Cranial Nerves, structural maps of the Autonomic Nervous System (Sympathetic vs. Parasympathetic changes), and critical pathological breakdowns.
