What is synaptic cleft?

A synaptic cleft is

What is synaptic fatigue ?

Which of the following is true about the synaptic cleft ?

Assertion Arival of an impulse at the axon terminal stimulates the release of neurotransmitters in synaptic cleft. Reason These neurotransmitters are responible for the opening of ion channels.

Movement of nerve impulse across synaptic cleft is primarily

Assertion : The chemical stored in the synaptic vesicles are termed as neurotransmitters. Reason : Synaptic vesicles release these chemicals in the synaptic cleft.

Consider the diagram of synapse (I) The numbered label indicate the location of the receptor moleucles (II) The number points to a synaptic vesicles (III) The number points of neurotrnsmitter (IV) The number points to synaptic cleft

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.
