Nervous System Test

It speeds up the transmission of impulses by acting as an electrical insulator.

It speeds up the transmission of impulses by integrating signal information more quickly.

It slows down the transmission of impulses by forming gaps called the nodes of Ranvier.

The energy conversion at the synapse involves converting electrical signals to chemical signals, which is necessary for transmitting information between neurons.

The energy conversion at the synapse involves converting chemical signals to mechanical energy, which is necessary for muscle contraction.

The energy conversion at the synapse involves converting light energy to electrical signals, which is necessary for vision.

. The energy conversion at the synapse involves converting thermal energy to chemical signals, which is necessary for temperature regulation.
