D)motor end plates.

Question

Quizplus · Accepted Answer

Intercalated discs are specialized structures that connect cardiac muscle cells to each other. They contain gap junctions, which allow for rapid electrical communication between cells, and desmosomes, which provide mechanical strength and prevent separation of the cells during contraction. Intervertebral discs are found in the spine and have no connection to cardiac muscle cells. Neuromuscular junctions and motor end plates are structures between nerve cells and skeletal muscle cells, not cardiac muscle cells.
