Striated muscle

Blood pressure is the pressure applied by blood on the walls of blood vessels, it is controlled by a negative feedback system where heart rate and blood volume need to be altered in order to control the pressure. Local negative feedback systems and heart rate is regulated but the cardiovascular centre which also in turn controls neural and hormonal mechanisms. Neurons regulate heart rate and contractility and some neurons inhibit, stimulate or control heart rate by causing constriction which…

athlete’s body physically. The goal of physical therapy is to get an athlete back to the point where he or she can perform normal tasks without difficulty, pain, or risk. The therapist uses exercises and rehabilitation to strengthen an athletes muscles, improve flexibility, and add stability to avoid future injuries. All of these are parts of physical therapy that help benefit the athlete by helping them gain strength and increases their ability to prevent injury. Many therapists in clinics…

the four muscles that make up the rotator cuff in the shoulder. The body of the tendon lies along the supraspinous fossa of the scapula and attaches laterally to the humeral head. Its purpose is to withstand the inferior gravitational exertions set over the shoulder joint due to the downward pull of the weight of the upper limb. Not only that, but the supraspinatus also helps the shoulder joint stay in place. The supraspinatus muscle is primarily used for abduction. It is a weak muscle in most…

rest as soon as possible, or attempting to do some weight bearing exercises or therapy to place some stress on the bones of the body. This will consequently increase the amount of bone growth. This will put more stress on the bones and the skeletal muscles surrounding them leading to an equilibrium between the amount of bone produced and absorbed.…

of injury is very high, but the rewards are worth it. Gymnastics is an amazing sport that provides many values, but there are challenges too. Anyone that is interested in doing gymnastics learns that gymnastics means exercise. The skills require muscle power, and lots of it. Gymnasts spend much of their time just doing conditioning. Conditioning means doing things like pushups, pullups,…

The musculoskeletal system provides form, support, stability and it is responsible for the movement of the body. The strong protective skeletal layer protects vital organs. For example rib cage protects the heart, kidneys and lungs from any traumatic injury. Bones provide framework that supports and keeps the body from collapsing. It is the major supporting structure of the body. The bone is classified by their shape or structure as cortical bones are dense and compact and cancellous is spongy.…

Sometimes, as we age, some parts of our body lose the ability to properly function. In our ankles, the bones and cartilage can break down, causing major discomfort and pain. The most major cause of this is ankle arthritis, when the gliding surface of the talus bone is worn down, and no longer has a smooth surface for joint motion. The ensuing friction between the talus bone and the fibula and tibia bones causes the discomfort and pain. While this isn’t a reversible problem, it is treatable. By…

Getting Relief From Plantar Fasciitis When you get out of bed in the morning, you have severe pain in the heel of your foot. It's possible you've developed plantar fasciitis (fashee-EYE-tiss). This is an overuse injury. Plantar fasciitis affects the sole of a person's foot. If you are diagnosed with plantar fasciitis, it means the tough band of tissue that connects your heel to the base of your toe is inflamed. Some people develop it from being overweight. If you have flat feet, you'll have an…

POSITION PAPER ON US AIR FORCE FITNESS STANDARDS 1. The purpose of this paper is to discuss why the US Air Force should change the current physical fitness standards. It will discuss why the current standards are not adequate enough to produce fit airmen, and recommend the steps that the US Air Force should take in order to ensure airmen are fit to fight. 2. The US Air Force requires airmen to maintain their own fitness measures and requires them to be fit in order to accomplish the mission.…

or others when using moving and handling procedures. Muscles act like levers and allow bone, at a joint, to act like hinges. Muscles pull and move bones at particular joints which makes the joint move and therefor the body moves. When a muscle contracts it pulls the bone at a joint in the direction in which it is designed to move. With reduced mobility muscles can become floppy which makes movement slower and more difficult but when the muscles are used regularly they remain firm and move more…
