Question

What is muscle fatigue. Define fascicle, myofibrils,myofilaments and sarcomere

Answer 1

Muscles are composed of tubular cells called myocytes, known as muscle fibers in striated muscle, and these cells in turn contain many chains of myofibrils. ... These proteins are organized into thick and thin filaments called myofilaments, which repeat along the length of the myofibril in sections called sarcomeres.
