Explanation -

Muscualr tissue of heart consists made up of elongated muscle fibers within there are numerous myofibrils.

The myofibrils show tranverse striations.

The fibers of cardiac muscle do not run in strict parallel formation, but branch and anastomosis with other fibers to form a network.

The nucleus of each myocyte is located centrally.

The junctions between adjoining cardiac myocytes are seen as dark staining transverse lines running across the muscle fiber.

These lines are called intercalated discs i.e adjacent cells are separated from one another by transverse lines called intercalated discs.

Cardiac muscle is involuntary and is innervated by autonomic fibers.
