What does the length of the reflex arc mean?

1, long reflex arc means to describe someone's slow reaction.

2. Reflex arc is a specific nerve structure of human body, that is, the nerve chain that receives external information and reacts. Because it takes time for information to transmit on reflex arc nerve cells, some people joked that the longer the reflex arc, the longer the reaction time of human body. For example, A tells a joke, B laughs at once, and C 10 minutes reacts to laugh. You can tease him at this time. The reflex arc is too long.
