Any of the major cytoplasmic process that arise from the cell body of a motor neuron is called _____.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Dendron
A motor neuron has a cell body (cyton) from which several short, branched cytoplasmic processes arise. Each of these major processes is called a dendron; it divides further into fine branches called dendrites, which carry impulses towards the cell body. The single long process that carries impulses away from the cell body is the axon.

Option (2) Dekatron — Incorrect. It is an old gas-filled counting tube used in electronic counters, not a part of a neuron.
