Nervous System: Neuron, Synapse, Reflexes · Zoology

Which of the following is a characteristic of 'Electrical Synapses' compared to chemical synapses?

  1. They are much slower
  2. They utilize neurotransmitters like dopamine
  3. They allow direct flow of ions through gap junctions
  4. They are only found in the peripheral nervous system
Show answer and explanation

Correct answer: They allow direct flow of ions through gap junctions

Electrical synapses feature gap junctions that physically connect the cytoplasm of two neurons. This allows for nearly instantaneous, bidirectional signal transmission, which is useful for synchronized activities like heart contractions.
