With powder coating, the bottom line is that the aluminum is covered with a coating which cannot be repaired should any peeling or blistering occur. Polished stainless steel differs from powder coating primarily in that the base material is not covered with a coating and the materials are substantially different.
The baroreceptor reflex or baroreflex is the body's way of responding to a change in blood pressure. Baroreceptors in the arteries notice that something has changed. When they sense a change in pressure, they send out signals through nerves to a part of the brain called the brainstem.
Proprioceptors are specialized sensory receptors on nerve endings found in muscles, tendons, joints, and the inner ear. These receptors relay information about motion or position and make us aware of our body position and movement in space. Proprioceptors detect subtle changes in movement, position, tension, and force, within the body.
