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.
There is no mechanical linkage between the accelerator pedal and the throttle valve with electronic throttle control. Instead, the position of the throttle valve (i.e., the amount of air in the engine) is fully controlled by the ETC software via the electric motor.he benefits of electronic throttle control are largely unnoticed by most drivers because the aim is to make the vehicle power-train characteristics seamlessly consistent irrespective of prevailing conditions, such as engine temperature, altitude, and accessory loads.
