6. FIG. 409 Muscles connecting the upper extremity to the vertebral column. (See enlarged image). The clavicular insertion of this muscle varies in extent; it sometimes reaches as far as the middle of the clavicle, and occasionally may blend with the posterior edge of the Sternocleidomastoideus, or overlap it.
In typical commercial aluminium anodizing processes, the aluminium oxide is grown down into the surface and out from the surface by equal amounts. So anodizing will increase the part dimensions on each surface by half the oxide thickness.
Many metals are structurally weakened by the oxidation process, but not aluminum. Aluminum can actually be made stronger and more durable through a process called ' anodizing '. Anodizing involves placing a sheet of aluminum into a chemical acid bath, quite often acetone in laboratory experiments.
