The devil is in the details. Together the spinal cord and the brain form the central nervous system (CNS). It is connected to the peripheral nervous system (PNS) which includes the nerves in our extremities. But, there are big differences between the two. Firstly the nervous cells (neurons) in CNS and PNS differ in ways such as their potential to regenerate. And, there are more cell types in the nervous system than just neurons. For a long time, those glial cells were regarded as mainly supporting cells (âgliaâ is ancient Greek name for glue).
â¢ ACCELERATOR PEDAL (noun). The noun ACCELERATOR PEDAL has 1 sense: 1. a pedal that controls the throttle valve. Familiarity information: ACCELERATOR PEDAL used as a noun is very rare.
The accelerator pedal sensors are used in electronic throttle control (ETC) or  drive by wire  systems, and the most common use of a wide open throttle sensor is for the kick-down function on automatic transmissions. Modern day sensors are non contact type.ome engine control units (ECUs) also control the throttle position electronic throttle control (ETC) or  drive by wire  systems and if that is done the position sensor is used in a feedback loop to enable that control.
