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.

Which of the following statement is correct. (A) The electrical potential difference across the polarised plasma membrane is called as action potential in resting stage. (B) Na^+ ion is responsible for generating an action potential. (C) The impulse is action potential

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

Which of the following events is involved in the transfer of information across a chemical synapse?(i) Neurotransmitters bind to the postsynaptic receptors.(ii)Calcium channels open in the presynaptic region.(iii) Ion channels open in the postsynaptic membrane.(iv) Direct flow of ions from one neuron to the next.

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

Read the following statements and find out the incorrect statements. a. A synapse is formed by the membranes of a pre-synaptic neuron and a post-synaptic neuron, which may or may not be separated by a gap called synaptic cleft. b. At electrical synapses, the membranes of pre-and post-synaptic neurons are in very close proximity. c. Electrical current can flow directly from one neuron into the other across chemical synapses. d. Impulse trasmission across a chemical synapse is always faster than that across a electric synapse. e. Electrical synapses are rare in our system.

A : Transmission of the nerve impulse across a synapse is accomplished by neurotransmitters . R : Transmission across a synapse usually requires neuro transmitters because there is space , i.e., synaptic cleft, that separates one neuron from another .
