Mapping the Nervous System

This lesson builds a clear map of the nervous system before the course moves into neurons, brain regions, senses, movement, autonomic control, and disorders. Students learn how the central and peripheral nervous systems are organized, how sensory input and motor output are routed, and why anatomical labels such as cranial, spinal, somatic, autonomic, sympathetic, parasympathetic, and enteric matter in practical understanding.

By the end, students should be able to describe the nervous system as an integrated communication network rather than a list of isolated parts. The lesson emphasizes orientation, major divisions, and functional flow while leaving detailed cellular mechanisms, specific brain-region functions, reflex physiology, and disease mechanisms for later lessons.
