Muscles are a type of tissue that are responsible for movement in the body. They are made up of long, thin fibers that contract and relax to produce movement. Muscles are important because they allow us to move, maintain posture, and generate heat. There are over 600 muscles in the human body. The three types of muscles are skeletal, smooth, and cardiac. The two basic types of muscle fibers are slow-twitch and fast-twitch. Different types of muscle contractions include isotonic, isometric, concentric, and eccentric contractions.
