membranes and therefore only stains cells with compromised membranes‚ indicating cell death‚ was used. This theory too was proven false. This seemed to indicate that it was not proliferation or death that caused it but reorganization of the cells. Muscular reconnection on the cut side could pull the arms to the cut side. To block muscle reconnection‚ we treated the cut ephyrae with cytochalasin D‚ which inhibits it‚ after the cuts healed sufficiently. The observation was that the muscle reconnection

Muscle Tissue Introduction * Motion * Results from alternating contraction (shortening) and relaxation of muscles * Skeletal system * Provides leverage and a supportive framework for this movement * Myology – study of muscles Muscle Tissue * Alternating contraction and relaxation of cells * Chemical energy changed into mechanical energy Types of Muscle Tissue * Skeletal muscle – primarily attached to bones * Striated and voluntary * Cardiac

3A/B PE STUDIES – REVISION NOTES Conservation of linear momentum when both objects are moving * In conservation of linear momentum the momentum of both objects before impact is not lost but remains the same for the combined momentum of both objects after impact. Example When playing snooker‚ once struck‚ the white “cue ball” will contain a certain amount of momentum. This is determined by its mass and how fast its travelling. When this ball makes contact with the black ball the total momentum

current. This current is usually proportional to the level of the muscle activity. An EMG is also referred to as a myogram. EMGs can be used to detect abnormal electrical activity of muscle that can occur in many diseases and conditions‚ including muscular dystrophy‚ inflammation of muscles‚ pinched nerves‚ peripheral nerve damage (damage to nerves in the arms and legs)‚ amyotrophic lateral sclerosis (ALS)‚ myasthenia gravis‚ disc herniation‚ and others. Why is an EMG test done? An EMG is often performed

It can be classified by many athletic associations as a muscle building supplement‚ much like anabolic steroids‚ and these associations take that into account when generating use policies for competition. However‚ there are many risks

How is the muscular system disrupted?: Muscles get weaker and are unable to function as they should (might need more but I wasn’t sure of the question) How is it diagnosed?: Diagnosed by combining the typical symptoms and the appearance on the tissue sample from the muscle

Your 10 Pounds of Muscle Plan Why do you want it? Here are some quick no nonsense reasons: 1. Muscle is a metabolic marker that tricks your body into thinking it’s younger. The more muscle you have‚ the younger you look. Don’t believe me? Find a muscular 75-year old guy at your gym. I guarantee he looks like he’s in his 50s. 2. Muscle burns fat. Muscle increases the amount of calories you burn throughout the day. Whether it’s 1 calorie or 1000 calories (another academic debate I don’t get into)‚
