which of the following helps in transmission of impulse across the synapse ?

Excitatory neurotransmitter involved in transmission of impulse at neuromuscular junction is

Type of synapse in which transmission of impulse across neuron is similar to conduction along a single axon

Which statements are incorrect for mechanism of nerve impulse conduction along electrical junctions of nerous or electrical synapse? i Nerve impulse flow directly from one neuron to other across the synapses in electrical synapses ii. Transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon iii. Impulse transmission across an elecetrical synapse is always faster than that across a chemical synapse. iv. Electrical synapses are rare in our system v. At an electrical synapse, the membranes of the pre and post-synaptic neurous are separated by a fluid-filled space called synaptic cleft is thick. vi. Chemicals called neurotransmitters are involved in the transmission of impulses at this synapse
