|
From cell body to dendrite and out axon terminal

Explanation:
Detailed explanation-1: -(a) Nerve impulse travels from dendritic end towards axonal end.
Detailed explanation-2: -The nerve impulse flows in one direction. The dendrites receive incoming nerve impulses from other neurons. This impulse travels from the dendrite to the cell body and then at the end of the axon transmits the impulse to another neuron or receptor.
Detailed explanation-3: -In the dendritic terminals, this nerve impulse is changed from a chemical to an electrical impulse after leaving the synaptic cleft. The impulse always travels from one dendron end of a neuron to another, from one axon to another.
