Summary Introduction
To review:
The reason as to why a nonvesicular synapse is more efficient than a vesicular synapse.
Introduction:
A synapse is defined as a site, where communication between a neuron and any other cell takes place. Synapses may occur on the cell body, axon and on dendrites. The axonal terminal is the place where a neuron forms a synapse with the other neuron. Communication using synapses involve the secretion of chemicals known as the neurotransmitters. A synapse is divided into two types: vesicular (chemical) and non-vesicular (electrical) synapse.

- In which of these ways does a metabotropic synapse differ from an ionotropic synapse? a. Its effects are slower to start and last longer. b. Its effects are faster to start and last longer. c. Its effects are slower to start and briefer in duration. d. Its effects are faster to start and briefer in duration.arrow_forwardAt a synapse, opening one sodium channel (for the normal duration before closing) causes a small depolarization. Opening a handful of sodium channels may cause a larger depolarization. Opening more channels may lead to an even larger depolarization, up to a point. Then the depolarization would be the same regardless of how many other sodium channels opened. Explain why the number of open channels increases the depolarization, and why it doesn’t matter beyond a certain point.arrow_forwardDescribe the difference between an electrical synapse and a chemicalsynapse.
