Muscle

Muscle refers to a tissue composed of fibers capable of contracting to produce movement in the body. These fibers, primarily made of proteins actin and myosin, generate force through a sliding filament mechanism. Muscles are essential for a wide array of functions, including locomotion, maintaining posture, facilitating organ function, and even generating heat. They can be voluntary (consciously controlled) or involuntary (controlled automatically) and vary in size, shape, and function depending on their location and role within the body. Furthermore, regular use through physical activity leads to hypertrophy, increasing their size and strength, while disuse can lead to atrophy or degeneration.
