Definitions:

Muscle Fiber Striations

The visible lines seen in skeletal and cardiac muscle fibers, resulting from the arrangement of actin and myosin filaments.

Electrical Junctions

Specialized connections between cells that allow for the direct transfer of ions and small molecules, enabling electrical communication.

Intercalated Discs

Specialized structures in cardiac muscles that connect cardiac muscle cells to each other, facilitating synchronized contraction of the heart.

Autorhythmicity

The ability of certain cells, especially cardiac muscle cells, to generate a rhythmical impulse spontaneously.
