The terminal buttons are:
A)the cell body of the neuron
B)fibers that extend outward from a neuron
C)tiny swellings at the end of the axon
D)small gaps between neurons

Question

Quizplus · Accepted Answer

The terminal buttons are also known as synaptic boutons or axon terminals. They are small swellings at the end of the axon that contain neurotransmitters, which are released into the synapse to communicate with other neurons or cells. Option A is incorrect because the cell body is also known as the soma and is located near the base of the neuron, whereas the terminal buttons are located at the end of the neuron's axon. Option B is incorrect because fibers that extend outward from a neuron can refer to either dendrites or axons, but the terminal buttons specifically refer to the end of the axon. Option D is incorrect because small gaps between neurons are known as synapses, which are the spaces where signaling occurs between neurons, but they do not refer specifically to the terminal buttons themselves.
