Question

Quizplus · Accepted Answer

Presynaptic cells are usually neurons that transmit signals towards the synapse, whereas postsynaptic cells can be neurons or other types of cells such as muscle fibers or gland cells that receive signals from the synapse. Choice A and B are incorrect as they incorrectly define presynaptic and postsynaptic cells as sensory or motor neurons. Choice D is incorrect as it reverses the roles of presynaptic and postsynaptic cells. Choice E is incorrect as it incorrectly associates presynaptic and postsynaptic cells with the peripheral or central nervous system.
