Saltatory conduction of impulse occurs in

Options

A. liver cells
B. non-myelinated nerve fibres
C. myelinated nerve fibres
D. None of these

Answer

C

Explanation

The fatty myelin sheath of myelinated nerve fibres prevents the flow of ions between external fluid and fluid present within the axon.At the node of Ranvier, the insulating myelin sheath is absent and thus, the ionic flow occurs at these points only.Therefore, the action potential jumps from node to node, due to which the transmission of impulse is more rapid in myelinated fibres. This is called the saltatory conduction of nerve impulse.
