- 1突觸（神經細胞之間傳遞訊息的接點）。台灣的生物課本用「突觸」，不要寫成「神經接點」，那不是專有名詞。
A synapse is the tiny meeting point between two nerve cells, especially in the brain. The surprise is that the two cells do not actually touch — there is a very small gap, and a message crosses it as a little squirt of chemicals from one side to the other. So a synapse is really a junction with a gap in it, not a join. Your brain has an enormous number of them, and learning something changes them: connections that get used a lot grow stronger, and ones you never use fade. That is why teachers and writers borrow the word outside science, and say things like 'my synapses aren't this morning' to mean their brain feels slow — that use is loose and joking, not technical. There is also a rarer verb, 'to synapse', used by for two cells forming such a connection; ordinary people never use it. The plural is 'synapses', with the last part sounding like '-seez'.
組成syn- 'together' + -apse from Greek haptō / hapsis, 'to fasten, a fastening' — a 'fastening together'. The English word was not old; the scientist Charles Sherrington needed a name for this junction and made one from Greek.
