The gap in the myelin sheath on the axon of certain neurons is called:
Open in App
Solution
The correct option is C Node of Ranvier
The axon can be defined as a long cytoplasmic process of the cell body of the neuron, which transmits the impulse from the cell body to other neurons. The axon in some neurons is covered by a lipid-rich membrane called the myelin sheath. There are periodic gaps in the myelin sheath on the axon. The region, where the axon is not covered by myelin sheath is called the node of Ranvier.
So, the correct answer is option (B).
