Explanation:
Detailed explanation-1: -Intercalated discs, also known as lines of Eberth, are responsible for connecting the cardiac muscles. It consists of fascia adherens, desmosomes, and gap junctions. It is specifically located at the longitudinal ends of each cardiac muscle cell.
Detailed explanation-2: -An intercalated disc allows the cardiac muscle cells to contract in a wave-like pattern so that the heart can work as a pump. Intercalated discs are part of the sarcolemma and contain two structures important in cardiac muscle contraction: gap junctions and desmosomes.
Detailed explanation-3: -Cardiac muscle cells are branched and contain intercalated discs, which skeletal muscles do not have.
