Muscles are tissues that enable movement by contracting and relaxing. They work with bones and joints to facilitate motion.
There are three types of muscles: skeletal, smooth, and cardiac. Each type has unique functions and locations in the body.
Skeletal muscles are attached to bones and allow voluntary movements like walking and lifting. They are controlled by the nervous system.
Smooth muscles are found in internal organs like the stomach and intestines. They handle involuntary movements such as digestion.
Cardiac muscles make up the heart and are responsible for pumping blood throughout the body. They work involuntarily and continuously.
Muscle contractions occur through a complex process involving calcium ions and proteins like actin and myosin. This process is vital for muscle function.
Regular exercise, proper nutrition, and adequate rest are crucial for maintaining healthy muscles. Keeping muscles strong supports overall health.
