Process for Generation and Conduction of Nerve Impulse
The neuron is known as the unit of the nervous system. It has three main parts-
- Axon
- Cell Body
- Dendrites
There are two axons depending upon the myelin sheath.
- Myelinated nerve: In some neurons, the axon is myelinated at intervals. The gaps which are in between them are known as nodes of Ranvier. They are mainly found in the white matter of the brain and spinal and cranial nerves.
- Non-Myelinated nerve: In these neurons the myelin sheath is absent. They are found in somatic and autonomic neural systems.
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.
