Supervisor, who introduced me to the topic of this book at the Indian Institute of Science, Bangalore, Karnataka, India. It is with great respect and admiration that I dedicate this book as a humble offering to their spirits. My basic education was imparted by many influential teachers at Saint Joseph’s Convent, Saint Joseph’s Indian High School, and Saint Joseph’s College in Mandya and Bangalore, Karnataka, India. My engineering education was provided by the People’s Education Society College of Engineering, Mandya, affiliated with the University of Mysore.

MU1 MU1 MU1 MU1 MU1 (b) At a slightly higher level of effort, with temporal recruitment, the firing rate of MU1 is increased. No other motor unit has been recruited yet. MU3 MU3 MU2 MU1 MU2 MU1 MU1 MU1 MU1 (c) At an even higher level of effort, with spatial recruitment, new motor units MU2 and MU3 have been brought into action.

Current flows from a depolarized region through the intracellular fluid to adjacent inactive regions, thereby depolarizing them. Current also flows through the extracellular fluids, through the depolarized membrane, and back into the intracellular space, completing the local circuit. The energy to maintain conduction is supplied by the fiber itself. Myelinated nerve fibers are covered by an insulating sheath of myelin. The sheath is interrupted every few millimeters by spaces known as the nodes of Ranvier, where the fiber is exposed to the interstitial fluid.
