Electrical impulses are sent through one electrode to stimulate the nerve. The second electrode records the impulse sent through the nerve as a result of stimulation. The time difference between stimulation from the first electrode and pickup by the downstream electrode is known as the latency. Nerve conduction latencies are typically on the ...
The most common everyday cause is temporary restriction of nerve impulses to an area of nerves, commonly caused by leaning or resting on parts of the body such as the legs (often followed by a pins and needles tingling sensation). Other causes include conditions such as hyperventilation syndrome and panic attacks.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Muscle cells work by detecting a flow of electrical impulses from the brain which signals them to contract through the release of calcium by the sarcoplasmic reticulum. Fatigue (reduced ability to generate force) may occur due to the nerve, or within the muscle cells themselves. [citation needed]
In neurology, Lhermitte phenomenon, also called the barber chair phenomenon, is an uncomfortable "electrical" sensation that runs down the back and into the limbs. The sensation can feel like it goes up or down the spine. It is painful for some, although others might simply feel strange sensations. [1]
Nerve conduction studies are beneficial to diagnose certain diseases of the nerves of the body. The test is not invasive, but can be painful due to the electrical shocks administered during the test. The shocks are associated with a low amount of electric current, so they pose minimal risk to the patients.
Pain also causes a behavioral change in the body, which is proportional to the intensity of the pain. The feeling is recorded by sensory receptors on the skin and travels to the central nervous system , where it is integrated and a decision on how to respond is made; if it is decided that a response must be made, a signal is sent back down to a ...
