Saltatory Conduction of Nerve Impulse
Fast transmission of nerve impulses occurs as depolarization which occurs only at the nodes of Ranvier which are present at intervals of the myelin sheath. Nerve impulse jumps from one node to another which is known as saltatory conduction of nerve impulses.
Feature of Saltatory Conduction:
- Energy usage is less in saltatory conduction in myelinated nerve fiber than the nerve impulse in the unmyelinated nerve fiber.
- Fast conduction of nerve impulse in myelinated nerve fiber than in unmyelinated fiber.
Generation And Conduction Of Nerve Impulse – NCERT Notes
CBSE Class 11- Neural Control and Coordination: The generation And Conduction Of Nerve Impulses consist of three steps – Polarization, Depolarization, and Repolarization. Due to the presence of active and electronic potentials along the conductors conduction of nerve impulses arises. The nerve impulse is the electric signal which passes along with the dendrites to generate a nerve impulse. Nerve impulse can either be depolarized or be in an action potential.
Generation and Conduction of Nerve Impulses, also known as Action Potentials. Neurons are the main factor that generates and conduct the impulse when they get any stimulus. Nerve impulses helps neurons to communicate and transmit information throughout the organism body. These electrical signals generat when there is a change in the electrical potential across the cell membrane of a neuron.
