Stimulus-Dependent Lab A motor unit is a motor neuron and the muscle fiber it controls. A whole muscle is made up of hundreds of motor units that are handled by different motor neurons that react at different levels of stimulation. The electric shock acts as an action potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become

Muscle fatigue occurs when a muscle has a diminished ability to continue to produce force‚ usually occurring due to extensive use of those muscles‚ such as when performing extraneous activity. On a molecular level‚ there are a number of things that happen that prevent the muscle from performing more action‚ ultimately to prevent any damage from being afflicted on the muscles cells. One particular effect that most people are likely familiar

talk about how BUILDING MUSCLE INCORPORATES MANY DIFFERENT FACTORS BUT CAN ULTIMATELY BE ACHEIEVED BY NUTRION‚ WEIGHT TRAINGING‚ AND ADDING SUPPLEMENTS TO YOUR DAILY ROUTINE. Let’s start with nutrition. There are hundreds of fad diets out there today‚ however the foundation of a successful nutrition plan begins a healthy calorie controlled diet. You must be eating a consistent amount of daily calories. This intake should be substantial enough to allow the body to build muscle. Undereating is one of

Cardiac This is an involuntary muscle‚ found solely in the walls of the heart‚ as well as in the walls of the blood vessels. This sort of muscle has similarities with the skeletal muscles‚ because it is striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions

of exercise are helpful for the body and health. Remember to breathe and have correct form or else the body could get injured. Also‚ always speak with a doctor before starting or continuing an exercise. Exercising can result in many different effects to the mind and body. From the moment a person starts exercising‚ the heart begins to exercise also. Exercise can cause noticeable effects on the heart (Sherwood 1). When the heart begins to exercise‚ the blood begins to pump harder throughout the
