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.

(November 2014). The lumbar plexus is a nervous plexus in the lumbar region of the body which forms part of the lumbosacral plexus. It is formed by the divisions of the first four lumbar nerves (L1-L4) and from contributions of the subcostal nerve (T12), which is the last thoracic nerve.Additionally, the ventral rami of the fourth lumbar nerve pass communicating branches, the lumbosacral trunk, to the sacral plexus.he femoral nerve is the largest and longest of the plexus' nerves. It gives motor innervation to iliopsoas, pectineus, sartorius, and quadriceps femoris; and sensory innervation to the anterior thigh, posterior lower leg, and hindfoot.
