This document contains a series of questions and answers about nervous tissue and the nervous system. It covers topics like nervous system histology, membrane and action potentials, synapses, neurotransmitters and integration. Some of the key points addressed include the types of neuroglial cells, where Nissl bodies and synaptic knobs are located, how myelin sheaths are produced, how the resting membrane potential is maintained, what occurs during an action potential, the roles of the presynaptic and postsynaptic membranes, and examples of different classes of neurotransmitters.
