Node of Ranvier is seen in -
Ans. is 'c' i.e., Axons o Nodes of Ranvier are periodic gaps in the myelin sheath on the axon.o Neuron is the functional unit (basic unit of nervous tissue).o It is specialized for the function of reception, integration and transmission of information in the body,o The basic structure of neuron is best studied in a spinal motor neuron,o This cell has a 'cell body (soma)' with 5-7 small processes called 'dendrites'.o There is a long process called 'axon' that originate from "axon hillock (A thickned area of cell body from which axon originates)".o The first portion of the axon is called "initial segment".o In a motor neuron, the axon hillock and the initial segment of axon have the low est threshold for excitation0o Functionally speaking, the neuron can be divided into four zones : -Dendrides and Soma (cell body) - Receptor zoneAxon hillock of body & initial segment of axon - Generator area (Nerve impulse is generated) QAxon (main length) : - Transmitter zone (Transmits nerve impulse).The nerve terminals (Terminal knobs or buttons) : - Release zone (release neurotransmitters).
