👉 Musculatures are the various muscle groups in the body, which are responsible for various functions such as movement, strength, and endurance. They include skeletal muscles (such as the heart, lungs, and muscles of the arms), cardiac muscle (which pumps blood throughout the body), smooth muscle (which relaxes when pressure is applied to it), and connective tissue (like tendons and ligaments). Muscles are also involved in various bodily movements such as walking, running, and jumping.
