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)

1.The atria does not perform any contractions since it is directly linked to the SA node. The SA node is being blocked was causes no signals to be sent to the atria muscle‚ resulting in no contraction of it. On the other hand‚ there will be contraction at 40 times per minute for the atrioventricular because this node has its own pacemaker which will allow it to spontaneously contract by depolarizing without any other signal or stimulus--thus‚ even though the SA node signals are blocked‚ the ventricles
