Common sites for IM injections include the following: 1. The ventrogluteal muscle is the preferred site for adults and children over the age of 1 year because there are no large nerves or vessels, it is a large muscle, it is sealed by bone and contains less fat (Berman et al., 2008). 2.
electromyogram (EMG). Recording of electrical activity of a muscle associated with contraction and relaxation. This is obtained by placing a microelectrode within a muscle.The recording process is called electro-myography. diagnostic test that records the electrical activity of muscles. In the test, small electrodes are placed on or in the skin; the patterns of electrical activity are projected on a screen or over a loudspeaker. This procedure is used to test for muscle disorders, including muscular dystrophy. Mentioned in: Myopathies.
2 Physiological Basis â¢ Muscle contraction due to a change in the relative sliding of thread-like molecules or filaments â¢ Actin and Myosin â¢ Filament sliding triggered by electrical phenomenon â¢ The recording of muscle APs is called electromyography â¢ What can be learned from an EMG? Time course of muscle contractionâ¢â¢ Coordination of several muscles in a movement sequence â¢ â¢ Field of Ergonomics: from the EMG conclusions about ___________ and the ____________ can be derived as well.
