Muscular Tissue
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.
striated muscle
smooth muscle
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
