Cardiac muscle ________.

A) has more than one nuclei per cell
B) has gap junctions and intercalated discs
C) lacks striations
D) none of the above

Intercalated Discs

Intercalated discs are specialized connections between heart muscle cells (cardiomyocytes), facilitating coordinated contraction through electrical and mechanical linkage.

Gap Junctions

Specialized intercellular connections that allow for direct communication between cells through the exchange of ions and small molecules.

Cardiac Muscle

A type of involuntary striated muscle found exclusively in the heart, responsible for heart contractions.

  • Elucidate the role of the cardiac muscle's configuration, focusing on the thickness of the ventricular walls, in performing its duties.
