The conditions mentioned are both a type of sclerosis, which refers to the hardening of a certain anatomical feature.
In atherosclerosis, the affected <u>anatomical feature </u>is the artery. This is a condition that causes the <u>obstructions </u>of <u>blood flow </u>through the artery as a result of plaque buildup along the artery walls. Unlike with MS, atherosclerosis does not present symptoms until the obstructions are severe or the plaque loosens, which can lead to <em>heart attacks</em>, among other consequences.
In the case of Multiple Sclerosis, the affected anatomical structure is that of the nerve. This is a condition for unknown reasons, causes the <u>immune system </u>to attack the myelin covers of nerve cells which act to protect the cell. The absence of this cover causes the build-up of plaque along the nerve axon, <u>stiffening </u>and <u>disrupting </u>the communication of the nerves with the central nervous system.
