Cardiac Muscle

Striated and branching muscle found only in the walls of the heart, controlled involuntarily.

Smooth Muscle

Non-striated muscle found in the walls of hollow organs, controlled involuntarily.

Striations

Obvious banding patterns found in skeletal and cardiac muscle tissues.

Intercalated Discs

Specialized junctions in cardiac muscle cells that connect them.

Tissues

Groups of similar cells that perform a specific function.
