Central Nervous System - Cita S. Amalia, MD, MSc

In this session, you’ll be introduced to how the Central Nervous System (CNS) works as the body’s ultimate control center. You’ll uncover how the brain and spinal cord are structured, how different regions handle decision-making, movement, senses, and memory, and why protection and energy supply are critical for brain function.

Beyond structure, you’ll also get a glimpse into the cells that make the brain work, surprising facts about neuron numbers, and how scientists actually study the brain. This module is designed to spark curiosity—enough to make you ask why and how, without giving everything away at once.
