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.
The Graphic Method Of Recording Muscle Contraction. In order to study the details of the contraction of muscle, the graphic method of recording the motion is applied. The curve may be drawn on an ordinary cylinder moving sufficiently rapidly.he rate of motion is registered by a tracing drawn by a tuning fork of known rate of vibration. In order that the muscle-nerve preparation may not be injured by the tissues becoming too dry, it is placed in a small glass box, the air of which is kept moist by a damp sponge.
