Vedclass · Answer

(A) Cardiac muscle cells are short,cylindrical cells joined end-to-end and by side branching to form a network. Intercalated discs are the dense junctions formed between cardiac muscle cells where they meet each other. These discs are specialized regions of the cell membranes that allow the rapid transmission of electrical impulses. Since cardiac muscle possesses considerable rhythmicity and generates its own wave of excitation,these discs function as boosters for the muscle contraction wave,ensuring that the heart contracts as a single unit (syncytium).

Assertion : Intercalated discs are important regions of cardiac muscle cells.
Reason : Intercalated discs function as boosters for muscle contraction waves.
