Question

In the following diagram showing axon terminal and synapse A, B, C, D and E respectively represents.

• A. A-axon terminal, B-synaptic cleft, C-synaptic vesicles, D-neurotransmitters, E-receptors
• B. A-axon terminal, B-synaptic vesicles, C-synaptic cleft, D-receptors, E-neurotransmitters
• C. A-synaptic cleft, B-synaptic vesicles, C-axon terminal, D-neurotransmitters, E-receptors
• D. A-synaptic cleft, B-axon terminal, C-synaptic vesicles, D-neurotransmitters, E-receptors
• E. A-synaptic vesicles, B-axon terminal, C-synaptic cleft, D-receptors, E-neurotransmitters

Answer 1

The correct option is B A-axon terminal, B-synaptic vesicles, C-synaptic cleft, D-receptors, E-neurotransmitters

A neuron is a structural and functional unit of the neural system. In a given diagram A represents axon terminals which are group of branches present at the end of axon, B represents synaptic vesicles which are present in the cytoplasm of synaptic knob, C represents synaptic cleft which is a gap present in between pre- and postsynaptic membrane, D represents receptors present in postsynaptic membrane which results in transmission of impulse to next neuron and E represents neurotransmitters which are the chemical substance present in synaptic vesicles and responsible for the transmission of impulse across the synapse.

Hence, the correct option is B.
