Cardiac surgery

Muscles work in pairs. one muscle contracts and pulls on the bones to which they are attached, in other word, Tendons which are fibrous connective tissue, muscle are attached to bones by tendons. The muscles contract to allow movement, while the skeletal gives the muscles support. The muscles and bones move together, basically with the muscles contracting the bones. The bone can not move back to its original state until another muscle pulls on it. Muscles work together to produce movement by…

The three types of muscle tissue are smooth, skeletal, and cardiac muscles. Smooth muscle tissue is a tissue in organ and blood vessel walls. It is involuntary and has spindle-shaped cells for pushing things through organs. The skeletal muscle is found in large body muscles. It is voluntary and is packed in bundles and attached to bones for movement. The cardiac muscle is involuntary and is found in the heart wall. It is a striated muscle with intercalated discs…

5. Normal muscle contraction occurs in a series of steps, and they are as follows: First, a motor neuron must have acetylcholine released in the synaptic cleft. The acetylcholine is then able to bind with receptors found in the cell membrane. This binding causes the Ca+/Na+ channels to open. The terminal cisternae then releases calcium into the muscle fiber. Calcium will begin to bind to troponin. The troponin moves tropomyosin out of the way since it blocks the actin’s active site. Next, actin…

health. Following the policy by the British Heart Foundation Lisa would be advised to engage in more physical exercises this helps reduce the risk of having another heart attack. When Lisa got discharged back to the community she was referred to the cardiac rehabilitation…

Usain bolt is the fastest man in the world using a lot of force to propel him self over the finish line in record times even though his hight isn't the ideal hight to be a sprint he needs to be faster than any of the other athletes. When usain bolt runs he puts a massive amount of force into the ground. With each quick stride he takes he generates a huge amount of force.the ground produces the same amount of force to propel bolt forward. Usain would need more force to propel him forward because…

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…
