Synapse

Definition

A specialized junction between two neurons, or between a neuron and an effector cell, where communication occurs through the release of chemical messengers called neurotransmitters. In the context of entomology and arachnology, synapses play a vital role in the functioning of the nervous systems of insects and arachnids.

Etymology

From Greek 'syn-', meaning 'together', and 'haptein', meaning 'to clasp'.

Example

Insects rely on synapses to process sensory inputs and coordinate their complex behaviors, such as flying and hunting.
