Transmission of nerve impulse at synapses is a

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

Synapse gap is present between which of the following ?

Read the following statements and find out the incorrect statements. a. A synapse is formed by the membranes of a pre-synaptic neuron and a post-synaptic neuron, which may or may not be separated by a gap called synaptic cleft. b. At electrical synapses, the membranes of pre-and post-synaptic neurons are in very close proximity. c. Electrical current can flow directly from one neuron into the other across chemical synapses. d. Impulse trasmission across a chemical synapse is always faster than that across a electric synapse. e. Electrical synapses are rare in our system.

A : Transmission of the nerve impulse across a synapse is accomplished by neurotransmitters . R : Transmission across a synapse usually requires neuro transmitters because there is space , i.e., synaptic cleft, that separates one neuron from another .
