I am not sure if this question means the adjective form or the adjacent form? However, a Schwann cell is a type of glial cell and its main function is to support neurons. Adjacent to the Schwann cell are nodes of Ranvier which are gaps in the myelinated axons, and are believed to assist in potential generation among other things.
The nucleus would be like the command center in the cell, because it monitors the cells functions and keeps everything "running smoothly".
The answer to that question would be C. temperature
