Core muscles refer to your abdominal muscles‚ although it takes more than developing your ab muscles to build it up. The muscles in your back‚ hips and pelvis must also be exercised if you want to develop a strong core. Having strong core muscles is essential for any modern woman. The demands of career and family (especially if you have infants and toddlers to lift and run after) make it imperative that we have core strength so we can do most physical activities with ease and facility. A weak core

INTRODUCTION OF MUSCULAR SYSTEM. Muscles tissue do is done by the coordinated contraction and release of millions of sarcomeres‚ tiny structures within the muscles cells. Muscle activity accounts for the most of the body’s energy consumption. All muscles tissues is strong. Most is enduring‚ some of it astoundingly so. Its cells are crowded with mitochondria‚ thousands of little factories constantly turning out molecules of ATP‚ a refined fuel. There are three types of muscles that can be found in our body

INTRODUCTION Smooth muscle fibers in different organs are distinctly different from each other in their physical dimensions‚ organization into bundles or sheets‚ response to stimuli‚ characteristics of innovation‚ and function. Smooth muscle is responsible for the contractility of hollow organs‚ such as blood vessels‚ the gastrointestinal tract‚ the bladder and the uterus. Specifically in the uterus‚ regulation of smooth muscle contraction is under the influence of an octapeptide known

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
