As an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.
When there is a short circuit inside the tube, usually from the cathode to the tube envelope, tube arcing happens. A brief loss of x-ray output and a localised artefact are the consequences. On transaxial computed tomography (CT) scans, it appears as a near-parallel, equidistant streak pattern, and on coronal and sagittal CT images, as a "horizontal" hypodense band.
The most frequent cause of x-ray tube failure is an inability to effectively disperse the heat produced during routine operation. It is common knowledge that at the anode target, heat accounts for 99% or more of the kinetic energy given to the electron beam.
Therefore, an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.

Answer:
The answer to the question: In what part of the spinal cord would you expect to find myelinated axons, would be, in the white matter of the spinal cord.
Explanation:
The spinal cord, the roadway and connection between the brain and the rest of the body, and a vital part of life itself, is formed by covering tissue, fluid, and most importantly, by the neuronal bodies and axons that form the entire system of the CNS, and ANS, and which also connect these systems with the PNS (peripheral nervous system), and the different organs. One visual characteristic of the cord is it having two colors, white and gray. The white matter surrounds the gray matter. The reason for this white color in the white matter, which is really the connecting filaments that go up and down the CNS, and connect with the gray matter, is that white matter neurons and axons are covered by myelin, an insulating and cushioning covering that surrounds the cell´s axons and also helps the nerve impulses move much faster and with higher precision, than in the white matter.
There are around 650 skeletal muscleswithin the typical human body. Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented in this article.
