Question

Which of the following is a long fiber-like part of a nerve cell?
A) an axon
B) a dendrite
C) a synapse
D) a vesicle

Accepted Answer

An axon is a long fiber-like part of a nerve cell that transmits electrical impulses away from the cell body towards other neurons, muscles or glands. Option B, dendrites are also finger-like protrusions that receive signals from other neurons towards the cell body. Option C, synapses are the tiny gaps between neurons where the transfer of messages occurs by the release of neurotransmitters. Option D, vesicles are small membrane-bound sacs that store and transport neurotransmitters within the nerve cell.
