CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)
