Read the assertion and reson carefully to mark the correct option out of the options given below: Assertion : Transmission of the nerve impulse across a synapse is accomplished by neurotransmitters. Reason : Transmission across a synapse usually requires neurotransmitters because there is small space i.e. synaptic cleft, that seperates one neuron from another.

Transmission of nerve impulse, across the sysnapse is accomplished by

Assertion. Transmission of a nerve impulse across a synape is brought about by a neurotransmitter. Reason. A neurotransmitter is necessary to transmit a nerve impulse across a synapse because there is a small gap, the synaptic cleft, between the two neurons at the synapse.

Nerve impulse are transmitted across a synapse from the

The chemical causing the transmission of nerve impulse across synapses is or The neurotranmitter which communicates between two neurons or between a neuron and a muscle a

The enzyme required for the conduction of nerve impulses across synapse is

Why conduction of nerve impulse across the synapse is always unidirectional from axon to dendron?

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
