Neural transmission across a mammalian synapse is accomplished by ________.
A) the movement of sodium and potassium ions from the presynaptic neuron into the postsynaptic neuron
B) impulses traveling as electrical currents across the synapse
C) impulses causing the release of a chemical signal and its diffusion across the synapse
D) impulses ricocheting back and forth across the synapse
E) the movement of calcium ions from the presynaptic into the postsynaptic neuron

Question

Quizplus · Accepted Answer

Neural transmission across a mammalian synapse is accomplished by the release of a chemical signal (neurotransmitter) from the presynaptic neuron into the synaptic cleft, followed by its diffusion across the synapse to bind to specific receptors on the postsynaptic neuron. This process is called synaptic transmission, and it allows for the transfer of information between neurons. Choices A, B, D, and E are incorrect because they do not accurately describe the process of synaptic transmission.
