In electrical synapses, the direct passage of ions and action potentials between adjacent cells is facilitated by

A. Ligand-gated channels
B. Synaptic vesicles
C. Gap junctions
✓
D. Neurotransmitter receptors

📝 Explanation

Electrical synapses do not use neurotransmitters; instead, they utilize gap junctions (connexons) that physically connect the cytoplasm of adjacent cells, allowing instantaneous, bidirectional current flow.
