Nerve Impulse Transmission Class 11 | Neural Control and Coordination | Biology | Photon classes

In this session, we explore the fascinating mechanism of Generation and Conduction of Nerve Impulses, a critical topic from Class 11 Biology (Neural Control and Coordination). This lecture is tailored for school students and medical aspirants (NEET), providing a clear breakdown of how electrical signals travel through our nervous system. What you will learn in this video: Resting Potential: How the neuron membrane maintains a polarized state at -70mV using the Sodium-Potassium pump. Generation of Nerve Impulse (Action Potential): The step-by-step process of depolarization when a stimulus is applied. Ion Channels & Permeability: Understanding the role of Ligand-gated and Voltage-gated sodium/potassium channels. Conduction of Impulse: How the signal travels along the axon through a series of depolarization and repolarization. Hyperpolarization & Refractory Period: How the neuron restores its resting state to become responsive to the next stimulus. This lecture simplifies complex biological graphs and concepts, ensuring you can answer both board exam questions and entrance-level MCQs with confidence.
