Explanation Trigger zones in neurons: In the case of the pseudounipolar neuron, there is only one process which extends out from the cell body. This process contains dendrites on one end and axon on the other end. The trigger zone in pseudounipolar neuron will be present where the dendrites and the projections merge. A bipolar neuron contains two main projections. These projections contain dendrites, and other contains axons. The signals travel from the dendrites to the cell body and then to the axons. Therefore, the trigger zone in case of the bipolar neuron will be the region where the cell body merges with eth axon. This region is called axon hillock...
