Definition of Unidirectional transmission and signal termination
Check what you remember
Read the wording for your board, then hide it and explain Unidirectional transmission and signal termination in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Synapses ensure one-way transmission and allow summation of impulses, and acetylcholinesterase breaks down acetylcholine to stop the signal.
