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.

The brachial plexus is a network of nerves that originate in the neck region and branch off to form most of the other nerves that control movement and sensation in the upper limbs, including the shoulder, arm, forearm, and hand. The radial, median, and ulnar nerves originate in the brachial plexus. Causes of a brachial plexus injury Brachial plexus injury (BPI) is an umbrella term for a variety of conditions that may impair function of the brachial plexus nerve network. The majority of pediatric and adult brachial plexus injuries are caused by trauma.
