MICROANATOMY

Detailed explanation-1: -Actin and myosin are two protein molecules in muscles and are mainly involved in muscle contraction in humans and animals. Both actin and myosin function by controlling the voluntary muscular movements within the body, along with the regulatory proteins known as troponin, tropomyosin and meromyosin.

Detailed explanation-2: -Note:The key difference between actin and myosin is that actin is a protein that produces small, contractile filaments within muscle cells, while myosin is a protein that produces thick, contractile filaments within muscle cells.
