Shape and Function of Muscle Tissues

Muscle Tissue

The tissue that helps in movement of body by its contraction and relaxation is called muscle tissue. It is the most abundant tissue in animals.

Muscle Fiber

Muscle tissue has large number of long cells in the form of bundle called muscle fiber.

Ø  There are three types of muscle tissues in animal’s body.

Skeletal Muscles

·         They also called striated muscles.

·         They are attached to bones.

·         Their cells are striped and many nuclei are present in it.

·         Their function is to provide movement to bones.

                                              

Smooth Muscles

·         They are present in blood vessels, urinary bladder, and in the walls of alimentary canal.

·         They are called non striated cells.

·         Each cell contain single nucleus.

·         There function is to provide movement to substances.

                          

Cardiac Muscles

·         The muscles that is present in the walls of heart.

·         They produce heart beat.

Skeletal muscles are voluntary in action.

Cardiac and smooth muscles are not under our control.

·         Striated cells are present and each cell contains a single nucleus.
