The nervous system is responsible for the control and regulation of body activities and functions. It has been classified into two different parts including the central nervous system (CNS), which consists of spinal cord and the brain, and the peripheral nervous system (PNS), which comprises the branching peripheral nerves. Cells of the nervous system are responsible for transmitting electrical impulses around the human body. Neurons and glial cells are the major types of cells found in the nervous tissues. Neurons interact and compute information provided by the nervous system. Glial cells are the supporting cells of the nervous tissue and are smaller in size as compared to neurons. This book aims to understand the interactions between nervous tissue cells. It strives to provide a fair idea about this topic to help develop a better understanding of the latest advances in the study of nervous tissue cells. The extensive content of this book provides the readers with a thorough understanding of the subject.
