Question

Unidirectional transmission of a nerve impulse through nerve fibre is due to the fact that (A) nerve fibre is insulated by a medullary sheath (B) sodium pump starts operating only at the cyton and then continues into the nerve fibre (C) neurotransmitters are released by dendrites and not by axon endings (D) neurotransmitters are released by the axon endings and not by dendrites

Tardigrade Admin · Accepted Answer

Transmission of nerve impulse through nerve fibre occurs unidirectionally because axon of one neuron linked to the dendrite of another neurone through synapse. Synaptic vesicles are filled with a neurotransmitter (e.g., Acetylcholine) released by axone endings not by dendrites.
