Introduction. Cellular movement is brought about by the interaction of the motor protein myosin with actin filaments. In cross-striated heart and skeletal muscle (Fig. 1b), these two proteins are arranged in a para-crystalline fashion to myofibrils, ensuring maximal force output.The basic unit of a myofibril is called a sarcomere and is defined as the region between two neighbouring Z-discs.

Explanation: Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. It is striated, branched, and contains intercalated discs, which help coordinate contractions. Unlike skeletal muscle, cardiac muscle cells have only one nucleus.There are striations in skeletal muscle.
