Solution

The correct option is B
Axon

Axon is the longest filament from the cell body which carries impulses from the cell body to outside. Dendrites are branches of dendron which receives impulses from the adjacent neuron. Axonites are the terminal branches of an axon. Schwann cells are cells which wrap around axons of neurons to form the myelin sheath.
