The most fascinating structure in the world-brain! Consists of nervous tissue
Components of nervous tissue Components: nerve cells: neuron, 1012 neurons in the human brain Glial cells: neuroglia Astrocytes Oligodendrocytes Microglia Schwan's cells Function: Neurons: sense, receive, process information initiate and conduct the nerve impulse Glial cells: support, protect, insulate and nourish neurons
