These tissues are composed of long, tube-shaped fibres, which are structured in parallel arrays and are mainly composed of numerous fine fibrils, called myofibrils. Muscular tissues play a vital role in contraction, relaxation and other bodily movements. There are three different types of muscular tissues: skeletal muscles, smooth muscles, and cardiac muscles.
These are special kinds of involuntary muscles.
The muscles of the heart are called Cardiac Muscles they perform rhythmic contraction and relaxation throughout our life.
They are cylindrical in shape, they have branches and there is a single nucleus.
Cardiac muscle consists of individual heart muscle cells connected by intercalated discs to work as a single functional organ
