Goal/Purpose: What do you want to do with this speech? I want to people to understand why building muscle is healthy for the body‚ and persuade others to want to build muscle. SPEECH Introduction: Write out the full introduction word for word. I am going to be talking about three different benefits that come from building muscle‚ and why I feel most people should incorporate muscle building into their work outs. Now I know that not everyone is too concerned with working out‚ and some people may

Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms

Over all muscle cars are just a better car to have. Yes tuner cars in better gas mileage and they are lighter. But muscle cars have more power and are faster. The first reason you should buy a muscle car is because you will get more respect than if you drove a tuner. You will get more respect in a and muscle car because more older

look manly”‚ but frankly this couldn’t be further from the truth. First of all the way women and men build muscle is completely different. Women don’t naturally have enough muscle building hormones‚ testosterone‚ to build muscle mass as easily as men do. When women build muscle it’s not the type of muscle you see on professional bodybuilders. It takes a very long time to build muscle and it’s not something that can suddenly happen overnight after

excitation-contraction coupling mechanism between skeletal and cardiac muscles. Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn‚ 2007) In the skeletal muscle‚ action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh)‚ at the neuromuscular junction. This initiates muscle action potential which is then

However‚ by observing my needs‚ I figured that I should most likely follow a diet that leads to muscle growth and that diet doesn’t have a particular name but can be called the “eat to gain weight/muscle diet”. To explain my choice‚ the main reason why I would like to do this diet is because my future occupation‚ which is to become a police officer‚ depends on it of course. Furthermore‚ I need to gain more muscle mass and weight because when being a police officer‚ you are most likely dealing with individuals

Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. _Energize the power stroke of the myosin cross bridge. 2. _Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke. 3. _Energizing the calcium ion pump. 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called hydrolysis. Write the end products of this process: ATP (+ H2O) (

Brain fart. I practiced that small thirty-second choreography over and over until it became muscle memory. I could have sworn I knew it so well I could perform in my sleep‚ but as soon as I met the intimidating gaze of my judge‚ I froze. When they taught the choreography during class a few hours prior‚ I felt no pressure and memorized every move with utmost precision. Any possible mistake I made would have been concealed by the other fifty dancers in the room. But right at a crucial moment during

The action of ANS-related drugs on smooth muscle Introduction In the following experiment‚ the key objective is to compare the mechanical changes in tonic force by longitudinal smooth muscle after the addition of different concentrations of the drugs noradrenaline and acetylcholine. Peristalsis is the wave of muscle contractions that allow circular muscles to constrict the gut and longitudinal muscles to shorten it in an attempt to move the food bolus towards the rectum.

Skeletal muscle is part of the three big muscle types‚ it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their
