What is muscular tissue? Describe structure and function of striated muscle fibres.

Muscular tissue is a contractile tissue made up of muscles. Muscles consists highly specialised cells called muscle fibres. This tissue is responsible for movement in our body.

Striated muscles are also called voluntary muscles as their movement is under our will. The cells of striated muscles are long, narrow, cylindrical, unbranched with blunt ends. They have multi nucleus.

These muscles are also called skeletal muscles because they are mostly attached to bone and help in body movement. These muscles show alternate light and dark band or striations when stained appropriately. As a result, they are also called striated muscles.
