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

A list of events occurring in the transmission of nerve impulse across the synapse is given below in a random order (i)Opening of specific ion channels allows the entry of ions, a new action potential is generated in the post-synaptic neuron. (ii)Neurotransmitter binds to the receptor on post synaptic membrane. (iii)Synaptic vesicle fuses with pre-synaptic membrane, neurotransmitter release into synaptic cleft. (iv)Depolarisation of pre-synaptic membrane. (v)Arrival of action potential at axon terminal. Which of the following options represents these events in a correct order ?

Which of the following statements regarding impulse transmission is incorrect ? I . Chemicals called neurotransmitters are involved in impulse transmission across the synapses. II. The membranes of the pre - synaptic and post - synaptic neuron are separated by an empty space called the synaptic cleft. III. The released neurotransmitters bind to the specific receptors present on the pre - synaptic membrane. IV. The new potential which develops is always excitatory.

The given diagram shows axon terminal.Select the option that correctly matches the steps in transmission of impulses (list i-vii) with the labellings (A-C) in diagram. (i)Chemicals called neurotransmitters are released in the synaptic cleft through ion channels. (ii)When an impulse arrives at the axon terminal, it stimulates the movement of synaptic vesicles. (iii)Neurotransmitters are endocytosed into the neurons. (iv)The ions channels close with the binding of neurotransmitters to their specific receptors vesicles. (v)Synaptic vesicles move towards the membrane where they fuse with the plasma membrane. (vi)Neurotransmitters are released in the synaptic cleft. (vii)The released transmitters bind to their specific receptors on post-synaptic membrane
