Which is the process of recording the electrical potential of skeletal muscles and nerves supplying them by inserting small needle electrodes into the muscles?

Which is the process of recording the electrical potential of skeletal muscles and nerves supplying them by inserting small needle electrodes into the muscles? Correct Answer EMG

Concept:-

  • Electro Myography (EMG) is the test done to measure the muscle response of electrical activity of muscles in response to nerve stimulation and the test is mainly done to detect neuromuscular abnormalities.
  • During this test, the needle shape structure is inserted into the nerves through the skin or muscles known as Electrodes.
  •  After the insertion of electrodes into the muscle, the activities of the electric potential of skeletal muscles are seen on the monitor known as Oscilloscope.
  •  Results are seen in the form of waves, as the electrodes are inserted, the body responds by slight and forceful muscle contractions.
  • Nerve conduction studies are also done for the same purpose as Electro Myography both are used to detect the nerve conduction of the muscles.
  • The patient may feel little pain and discomfort during the EMG study.
  • EMG results show nerve damage and dysfunctions in the nerves and the signs of nerve damage are:
    • Numbness or tingling sensations in the extremities
    • Peripheral Muscle weakness
    • Unable to hold the objects
    • Sharp prickling pain at the extremities

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. What do we see when we look at an object?
