AAET NCV/EMG QUESTIONS WITH 100% CORRECT ANSWERS.

Ion What describes an atom in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge? Electron What is the negatively charged particle in an atom? Neutrons What has neutral particles, along with protons, and is found in the nucleus of an atom? Protons Which particles of an atom are positively charged? Atoms What makes up the elements found in all matter? -90 to -70mV What is the voltage inside t...

A-waves or Axon reflex Seen when using sub- maximal stimulation during the F-wave recording. Consistent in latency and amplitude and usually occurring before the F-wave. Thought to be a result of reinnervation of the nerve. Abduct Move away from the median plane Abductor digiti minimi (ADM or ADQ) Ulnar innervated muscle on the medial side of the little finger alongside the 5th metacarpal. The most superficial muscle in the hypothenar eminence. Commonly used when recording ulnar m...

Phsiatrists and neurologists Who else besides PTs can perform EMG/NCV testing? Individual state practice acts What regulates PTs ability to perform EMG/NCV testing? Michigan, west Virginia, Hawaii and NJ In what states is EMF/NCV testing not allowed in No Does EMG/NCV determine a specific diagnosis 100-200 cases under a trained electromyographer, continuing education courses. Loose because there is no regulatory body What qualifications are required to perform EMG/NCV testing? Are qu...

When the synaptic vesicles are electrically stimulated by a nerve impulse, synaptic vesicles gravitate to the outer membrane of the presynaptic wall and release acetylcholine into the synaptic cleft. The Ach molecules migrate to the postsynaptic cells where they attach to the specific receptors. When enough neurotransmitters are received by the receptors to overcome the firing threshold a CMAP is generated causing muscle contraction. This describes The events that occur in the Neuromuscular Junc...

motor unit A motor neuron and all of the muscle fibers it innervates and composed of: 1. anterior horn cells 2. axon 3. neuromuscular junction 4. muscle fiber innervated by nerve motor neurons neurons that carry signals from the spinal cord to the muscles to produce movement MUAP the summation of electrical potential from all the fibers of that unit close enough to the electrode artifact unwanted electrical activity that arise outside the tissue bring examined True or False: th...

Nerve Fiber bundles having a common destination describes Fascicles What muscle fibers called slow twitch muscle fiber Type I Which muscle fiber is called fast twitch muscle fiber Type 2-A and 2-B What is an interconnection of components such that current flows and one or more close loops Circuit What is an electrical device that provide specific resistance used to control current and voltage and electrical circuits Resistors What reduces total resistance and is the sum of individ...
