Ohm's Law states that an electrical circuit's current is directly proportional to its voltage, and inversely proportional to its resistance. So, if voltage increases, for example, the current will also increase, and if resistance increases, current decreases; both situations directly influence the efficiency of electrical circuits.
Lumbosacral Radiculopathy Definition. Lumbosacral radiculopathy is a broad term referring to a range of symptoms associated with the nerves of the lumbosacral plexus in the lower back. The lumbosacral plexus encompasses the nerves that exit the spinal cord at the lumbar, sacral and coccygeal regions of the spine.Radiculopathy occurs when an anatomical abnormality has caused one or more of these nerves to become irritated, pinched or impinged.he lumbosacral plexus encompasses the nerves that exit the spinal cord at the lumbar, sacral and coccygeal regions of the spine.

Primary lateral sclerosis (PLS) is a rare neuromuscular disease characterized by progressive muscle weakness in the voluntary muscles. PLS belongs to a group of disorders known as motor neuron diseases.Motor neuron diseases develop when the nerve cells that control voluntary muscle movement degenerate and die, causing weakness in the muscles they control.nset of PLS usually occurs spontaneously after age 50 and progresses gradually over a number of years, or even decades. The disorder usually begins in the legs, but it may start in the tongue or the hands.
