" The new potential developed in the post-synaptic neuron is: "

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 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

Define the term: Post-synaptic neuron.

Define the term: Pre-synaptic neuron.

The following steps are involved during synaptic transmission. Rearrange them in correct order. a) Release of neurotransmitter at synaptic cleft. b) Generation of a new potential at post synaptic neuron c) Arrival of impulse at the axon terminal d) Binding of neurotransmitter with specific receptor e) Movement of synaptic vesicle towards the membrane.
