A synaptic cleft is

Movement of nerve impulse across synaptic cleft is primarily

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

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

What in a synaptic cleft ?

Which of the following is true about the synaptic cleft ?

Which of the following is true about the synaptic cleft ?

Do you know how the pre-synaptic neuron transmits an impulse (action potential) across the synaptic cleft to the post-synaptic neuron?

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.
