Verified step by step guidance

Understand the basic structure of muscle tissue: Muscle tissue can be categorized into three types - skeletal, cardiac, and smooth muscle. Each type has distinct characteristics and functions.
Identify the characteristics of skeletal muscle: Skeletal muscle is characterized by its striated appearance due to the arrangement of actin and myosin filaments. It is under voluntary control and is primarily responsible for movement.
Identify the characteristics of cardiac muscle: Cardiac muscle is also striated, similar to skeletal muscle, but it is found in the heart and is under involuntary control. It has unique features such as intercalated discs that facilitate synchronized contraction.
Compare the similarities between cardiac and skeletal muscle: Both cardiac and skeletal muscles have a striated appearance due to the presence of sarcomeres, which are the repeating units of actin and myosin filaments.
Conclude the similarity: The correct similarity between cardiac and skeletal muscle is that both have striations, which is a result of their sarcomeric structure.
