Nerve impulse
A. during the propagation of a nerve impulse, the action potential results from the movement of K  ions from extracellular fluid to intracellular fluid
B. electrical synapses are very rare in the human system
C. receptor sites for neurotransmitters are present on the pre­synaptic membrane
D. when the impulse reaches the presynaptic region, synaptic vesicles break and release neurotransmitters
E. impulse through nerve fibers is unidirectional because nerve fibers are insulated by a medullary sheath
Choose the correct answer from the options given below:
1. A and E only
2. B, C and D only
3. C, D and E only
4. B and D only

An action potential in the nerve fibre is produced when positive and negative charges on the outside and the inside of the axon membrane are reversed, because
1. More potassium enters the axon as compared to sodium ions leaving it
2. More sodium enters the axon as compared to potassium ions leaving it
3. All potassium ions leave the axon
4. All sodium ions enter the axon
