Which of these statements correctly describes gap junctions?

Question

Quizplus · Accepted Answer

Gap junctions are specialized channels that allow direct communication between adjacent cells, permitting the passage of various molecules and ions. They are present in many cell types, including neurons, cardiac muscle cells, and smooth muscle cells. In neurons, gap junctions allow for the spread of action potentials from one neuron to another, while in muscle cells, they facilitate synchronous contractions. They are not specific to any particular muscle type or tissue. The autonomic nervous system does not directly connect to smooth muscle cells through gap junctions, but rather indirectly through neurotransmitters and other signaling molecules.
