The pathway that permits electrical activity to pass from cell-to-cell in myocardial tissue is the
A)desmosome
B)septum
C)gap junction
D)T-tubule
E)sarcoplasmic reticulum

Question

Quizplus · Accepted Answer

Gap junctions are specialized intercellular channels that allow for direct electrical communication between adjacent cells. These channels are critical for the coordinated contraction of heart muscle cells, allowing for the rapid spread of electrical impulses throughout the myocardium. Desmosomes are anchoring junctions that provide mechanical strength and stability to tissues, while the septum is a physical barrier between the right and left sides of the heart. T-tubules are invaginations of the sarcolemma that allow for the deep penetration of action potentials into the interior of muscle cells, while the sarcoplasmic reticulum is an organelle that stores and releases calcium ions for muscle contraction.
