Additionally, marble and limestone can be scratched more easily than harder stones such as granite. Marble is, however, sometimes used in the kitchen as a pastry slab; its perfectly smooth, cool surface is ideal for rolling out dough and piecrusts.ike marble, polished limestone is subject to surface changes or damage from kitchen acids including citrus juices, vinegars, mustards, and so forth. Unsealed, some of the more porous limestones can be subject to stains.
Patient Forums. Your doctor has just ordered a test called an EMG. EMG stands for Electromyogram which loosely translated means electrical testing of muscles but in fact has come to mean electrical testing of nerves and muscles. The EMG is performed by a specialist, the Electromyographer, who is usually a Neurologist or a Physiatrist.
Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease. Muscles are stimulated by signals from nerve cells called motor neurons. This stimulation causes electrical activity in the muscle, which in turn causes contraction. This electrical activity is detected by a needle electrode inserted into the muscle and connected to a recording device. Together, the electrode and recorder are called an electromyography machine.
