Woodworkers set up, operate, and tend all types of woodworking machines, such as saws, milling machines, drill presses, lathes, shapers, routers, sanders, planers, and wood-fastening machines. Operators set up the equipment, cut and shape wooden parts, and verify dimensions, using a template, caliper, and rule.
Cerebrum: The cerebrum develops from the embryologic forebrain. It is the largest part of the brain and represents @ 85% of the brain's total weight. The cerebrum is divided into two hemispheres separated by a deep longitudinal fissure extending from the front to the back of the brain.
Cerebrum is the largest and the most prominent part of the brain, whereas the cerebral cortex is the outer layer of the cerebrum. Cerebral cortex is actually a part of the cerebrum. The human cerebral cortex is actually made up of approximately 10 billion nerve cell bodies and their dendrites, whereas the cerebrum has both cell bodies and nerve fibers. The cerebrum has both gray and white matter, whereas the gray matter is considered to be the cerebral cortex.
