Synapse MCQ - Practice Questions with Answers

The Synapse

• Synapse can be defined as a functional junction between parts of two different neurons.
• There is no anatomical continuity between two neurons involved in the formation of the synapse.
• At a synapse, the membrane of the first neuron is called the presynaptic membrane, and the membrane of the next neuron is called the postsynaptic membrane.
• The small gap between is the synaptic cleft.
• Transmission across a synapse is carried out by molecules called neurotransmitters, which are stored in synaptic vesicles in the axon terminals.
• Two main neurotransmitters in vertebrates nervous system are acetylcholine and noradrenaline.
• Neurons releasing acetylcholine are described as cholinergic neurons.
• Neurons releasing the adrenaline are described as adrenergic neurons.
