How do Striated Muscles work?
Striated muscles work through a coordinated process of contraction and relaxation, enabling voluntary movements in the body and composed of long, cylindrical cells called muscle fibers, these muscles are organized into bundles known as fascicles. Within muscle fibers, actin and myosin filaments create sarcomeres, the basic units of contraction. When a nerve impulse stimulates the muscle, calcium ions are released, allowing myosin heads to form cross-bridges with actin filaments.
This initiates a power stroke resulting in muscle contraction. The neuromuscular junction, where nerves communicate with muscle fibers, plays a crucial role in initiating this process. Muscle relaxation occurs when calcium ions are transported back preventing further cross-bridge formation.

What are Striated Muscles and Their Functions?
Striated muscle, also known as skeletal muscle, is a type of muscle tissue characterized by its striped or striated appearance and it plays an important role in the movement of the human body. Striated muscles are composed of long, cylindrical cells known as muscle fibers.
These muscles are characterized by their striped or striated appearance under a microscope that shows the organized arrangement. This article helps in understanding the biology of striated muscles which is essential to know how our bodies move, maintain posture, and perform various physical activities.
