Root Explanation

Postsynaptic → It is formed from "post-" (meaning after) and "synaptic" (from Greek "synapsis", meaning connection). The word "postsynaptic" refers to the part of a neuron that receives signals after the synapse, or connection, has occurred.

Memory Tip

Think of 'post-' meaning 'after' and 'synaptic' relating to connections between neurons — so postsynaptic refers to the part that receives signals after the connection.
