Which of the following statements regarding impulse transmission is incorrect ?
I . Chemicals called neurotransmitters are involved in impulse transmission across the synapses.
II. The membranes of the pre - synaptic and post - synaptic neuron are separated by an empty space called the synaptic cleft.
III. The released neurotransmitters bind to the specific receptors present on the pre - synaptic membrane.
IV. The new potential which develops is always excitatory.

What is Synaptic Cleft?

Which option is correct for conduction of nerve impulse along chemical synapse? i. At synapse, the membranes of the pre and postsynaptic neurons are separated by a fluid-filled space called synaptic cleft ii. Chemicals called neurotransmitters are incolved in the transmission of impulses at these synapses iii. The axom terminals contain vesicles filled with these neurotransmitters iv. When an impulse arrives at the axon terminal, synaptic vesicles release their neurotransmitters in the synaptic cleft. v. The release neurotransmitters bind to their specific receptors, present on the pre-synaptic membrane. vi. Opens ion channels allowing the entry of ions which can generate a new potential in the postsynaptic neuron vii. The new potential developed is only excitatory
