A functional syncytium

Question

Quizplus · Accepted Answer

A functional syncytium is a group of cells that function as a single unit by sharing their cytoplasm through gap junctions, which allows for coordinated contraction. This is found in both the heart and single-unit smooth muscle, allowing them to contract as a coordinated unit. Option A refers to agonist and antagonist muscles, which may work together to create movement, but are not a functional syncytium. Option C refers to a type of muscle fiber and is not related to the concept of a functional syncytium. Option D is the opposite of a functional syncytium, where cells contract independently rather than as a coordinated unit. Therefore, the correct answer is B.
