Chapter 2: Neurons and Glia 1. Introduction * Although there are many neurons in the human brain (about 100 billion)‚ glia outnumbers neurons by tenfold. 1:10 ratio. * Neurons are the most important cells for the unique functions of the brain. * Neurons sense changes in the environment‚ communicate these changes to other neurons‚ and command the body’s responses to these situations. * Glia‚ or glial cells‚ are thought to contribute to brain function mainly by insulating‚

speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring. A series of photomicrographs and schematic illustrations show myelinated nerve fibers. Panel A is an illustration of a single neuron with major structures labeled. Panel B is an illustration of a cross section of a neuron that shows a myelin sheath wound around an axon
