Biology · Nervous System
In a chemical synapse, nerve impulses are transmitted unidirectionally from the axon of one neuron to the dendrite of another. Under normal physiological conditions, why is the reverse direction of nerve impulse transmission prevented?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1Because neurotransmitter receptors are present only on the postsynaptic membrane and neurotransmitters are released only from the presynaptic terminal✓
- 2Because myelin sheaths block reverse conduction
- 3Because axons cannot conduct electrical impulses
- 4Because dendrites lack neurotransmitter receptors
Correct answer
Because neurotransmitter receptors are present only on the postsynaptic membrane and neurotransmitters are released only from the presynaptic terminal
