Muscle Histology

Muscle histology examines the microscopic structure of muscle tissue, revealing how muscles are built and function. Muscles are composed of specialized cells called muscle fibers, which contain protein filaments responsible for contraction. These fibers are organized into bundles, allowing muscles to generate force and movement. There are different types of muscle tissue—skeletal (voluntary movements), cardiac (heart function), and smooth (organs). Studying muscle histology helps scientists understand how muscles grow, repair, and respond to training or injury, providing insights into muscle health and disease at a cellular level.
