State any three points of difference between your limb and heart muscles.

(N/A) $(i)$ Muscles present in our limbs are voluntary,meaning they move or pause when we consciously decide to do so. In contrast,heart muscles are involuntary,exhibiting rhythmic contraction and relaxation throughout life without conscious control.
$(ii)$ Limb muscles are typically attached to bones and facilitate body movement,whereas heart muscles are not attached to bones and are specialized for the continuous pumping of blood.
$(iii)$ The cells of limb tissue (skeletal muscles) are long,cylindrical,unbranched,and multinucleate,while heart muscles (cardiac muscles) are cylindrical,branched,and uninucleate.
