Motor function and motor control begin in the motor cortex of the brain. The primary motor cortex is associated with generation of a motor program. Premotor areas are involved in complicated motor functions, such as required changes in output forces or velocities, or motor response to visual or auditory input. Also, the basal ganglia and thalamus are important coordinating centers for goal­directed motor programs and patterns. The cerebellum allows for unimpeded movements of those motor programs…

Tissue in your body is used to help your body move to bend over and pick up a box that is on the floor. Muscular tissue is used to move muscles and bones and connective tissue connects the muscles/tendons to the bones to help with movement. Nervous tissue is also used. It’s needed to tell you to pick up the box and tell your muscles and bones to move the way you do to bend over to pick the box up. First, the rectus abdominus pulls forward to bend over, the latissimus dorsi and gluteus maximus…

INTRODUCTION: An individual’s level of strength is not only dependent upon on the muscles involved in an action but also the nervous systems ability to activate the appropriate muscles at any one time. It is well known that resistance training can lead to an increase in maximal contractile muscle force (Aagaard et al., 2002) however; this adaptation is not primarily explained by an increase in muscle volume or muscle cross-sectional area but adaptive changes within the nervous system.…

Diseases of the muscular system grow more rapidly each day, especially since we use our muscles on a daily, hourly, minute, and second basis. One of the most common diseases, affecting an estimated 2 to 7 percent of the general population, is fibromyalgia. This is a chronic (long lasting) condition in which widespread body pain occurs for more than three months. Symptoms that accommodate this condition includes, but not limited to: fatigue, sleeping disorders, depression, irritable bowel…

CPR Mask Response Heart disease and sudden cardiac arrests in people around the world are rapidly on the increase due to a number of health problems. Knowing how to address the situation on how to perform CPR including the removal of the ventilation mask from the packaging to applying the mask correctly and performing the CPR correctly can be the difference between life and death. When a single rescuer without any CPR training when faced with the problem of performing CPR can face many problems…

described above. This is a major protein produced by the MYH7 gene and comprises the thick filament in cardiac muscle and plays a major role in cardiac muscle contraction. Mutations of this MYH7 cause excess thickening of the cardiac muscle, namely the left ventricle wall. It is not known how the mutation of MYH7 causes this thickening, but this thickening causes a functional impairment of the cardiac muscle. This thickening is found in those with hypertrophic cardiomyopathy (HCM), which is the…

aiding those in sudden cardiac arrest distress. Before becoming a certified Emergency Medical Technician (EMT), I was completely unaware of the Good Samaritan Laws. In fact, I fallaciously believed that medical equipment such as an AED could only be handled by medical professionals. The widespread lack of awareness of Good Samaritan Laws prevents many from assisting in a sudden cardiac arrest situation. The fear of lawsuits may deter individuals from providing assistance in a cardiac arrest…

Persons. They began the first attempts at dealing with sudden cardiac arrests and heart attacks. The group organized a set of rules to follow in case there was ever a situation in which a person could have drowned (History of CPR). The movement has since gained immense popularity, saving about 92,000 lives each year. In 1960, the American Heart Association started a program helping physicians become familiar with close-chest cardiac resuscitation, and now has now developed into a program…

Therapeutic hypothermia in cardiac arrest has shown improved neurological outcome rate in multiple trials. Current AHA guidelines report Class 1, Level B recommendation of therapeutic hypothermia for cardiac arrest with out-of-hospital shockable rhythm while it is a Class 2b, level B recommendation for in-hospital cardiac arrest with any rhythm or out of hospital arrest with a non- shockable rhythm. In North Shore Medical Center, therapeutic hypothermia is offered to all cardiac arrest patients…

Muscles help provide strength, endurance, and help to keep the body warm. Muscles help keep the body warm by continuously pumping blood out of the heart and by body movement. There are three main categories of muscles in the human body: skeletal, cardiac, and smooth (non-striated) muscles. One type of muscle, known as skeletal, controls mobility. It is the only type that is voluntary and is also striated. Everyday living activities are performed using the majority of the skeletal muscles…
