Question

Quizplus · Accepted Answer

Cardiac muscle tissue is composed of small cells with branching ends, which allows for communication and coordination of contractions. Each cell has a single, centrally located nucleus. It is a specialized type of muscle tissue that is responsible for the contraction of the heart and maintaining circulation. It contracts involuntarily, meaning that it does not require nervous stimulation. Cardiac muscle tissue has limited regenerative capacity and cannot replace large numbers of cells after injury.
