Question 41

At a chemical synapse, the tiny junction between cells, what carries the signal across the gap?

  1. Red blood cells circulating through the gap
  2. Bones that bridge the two cells
  3. Fused axons with no space between them
  4. Neurotransmitter moleculesCorrect answer

Explanation

The sending cell releases neurotransmitters that cross the synaptic gap and bind to the receiving cell. The cells do not need fused axons, because chemical signaling specifically works across a small separation.
