Answer: Anaesthesia blocks or impairs impulse transmission which helps patients not to feel pain during surgery

Explanation: . Local anesthesia affects the neural processes usually at the nodes of Ranvier by reducing the rate at which sodium ions(which are positive) flow through the membranes. Local anesthetics blocks sodium influx into the cell membranes ensuring that the minimum threshold for transmission is not reached thereby causing no pain.

General anesthesia on the other hand opens Chloride ions(which are negative ions) channel thereby allowing chloride to flow into the cell membranes causing hyperpolarization. As the negative ions increase, this shifts the membrane potential away from the minimum threshold thereby blocking the pain during surgery.

A magenta dashed line surrounds certain uncontrolled airports what does this indicate and what is its significance to vfr pilots
DENIUS [597]

A dashed magenta line indicates the boundary of the Class E Surface Area.

Using visual flight rules (VFR) is the most crucial aspect of flying an aeroplane. Simply said, VFR refers to a set of rules that allow an aircraft to fly in clear visual conditions, such as on sunny, clear days. Your major goal as a pilot will be to learn these protocols by heart and carry them out gracefully.

One of the following four lower restrictions applies to Class E: surface, 700' AGL, 1200' AGL, or 14,500' MSL (discussed below). A Class E lower restriction of 1200' AGL applies to the majority of the nation. It is shown by a broad magenta line with a fuzzy side as it lowers to 700' AGL. The side where the floor of Class E is 700' AGL is the fuzzy side.

The "Class E Surface Area" is the area below the floor that may descend to the top. The Class E Surface Area limit is denoted by a dashed magenta line.

So, you can see the dashed magenta line indicating the outer boundary of the Class E Surface Area around the airport and outside of that, a meandering wide magenta line showing where the floor of Class E goes from 700' agl to 1200' agl as you go away from the airport. The floor of Class E will be indicated in the text when you hover your mouse over the image and keep it motionless.
