Question

The node of Ranvier on an axon is the

• A. point of contact between two neurons
• B. short branched processes
• C. points devoid of myelin sheath
• D. fine fibres in the neuroplasm

Answer 1

The correct option is C points devoid of myelin sheath

In some myelinated neurons, there are points on the axon where the myelin sheath is absent. These are called nodes of Ranvier. They help to conduct impulses faster.


Dendrites are the short, branched processes in a neuron which receives the neuronal signal.

The neuroplasm is the cytoplasm present in a nerve cell and contains many fine fibres called neurofibrils.

The point of contact between two neurons is called the synapse. Synapse functions in the transmission of nerve impulses.
