Which type of muscle tissue is characterized by striated muscle fibers and involuntary control?

The type of muscle tissue that is characterized by striated muscle fibers and involuntary control is cardiac muscle. Cardiac muscle is unique in that it comprises the walls of the heart and is responsible for pumping blood throughout the body. Its striated fibers allow for a coordinated contraction, which is necessary for efficient blood circulation. Unlike skeletal muscle, which is also striated but under voluntary control, cardiac muscle operates autonomously through intrinsic electrical signals, making it involuntary. This means that it functions without conscious effort, allowing the heart to maintain a steady rhythm.

On the other hand, skeletal muscle is associated with voluntary movement and is under conscious control, which is distinct from the function of cardiac muscle. Smooth muscle, while involuntary, lacks striations and is found in structures like the intestines and blood vessels. Connective muscle is not a recognized type of muscle tissue. Thus, the defining characteristics of cardiac muscle—striations and involuntary control—clearly identify it as the correct answer.
