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.
Sequence. In a simple reflex action: stimulus â receptor â sensory neurone â relay neurone â motor neurone â effector. An effector is any part of the body that produces the response.Here are some examples of effectors: 1  a muscle contracting.2  a gland releasing (secreting) a hormone or other chemical.eflex actions. When a receptor is stimulated, it sends a signal to the central nervous system, where the brain co-ordinates the response. But sometimes a very quick response is needed, one that does not need the involvement of the brain. This is a reflex action.
