What happens in a reflex arc?
What happens in a reflect action is show by a reflex arc. The links in a reflex arc are: stimulus>receptor>sensory neurone>motor neurone>effector>response.
Neurones are adapted by being long, having branched endings (dendrites) to pick up impulses and having an insulator sheath.

What is a synapse?
A synapse is a gap between neurones. The arrival of an impulse triggers the release of a transmitter substance, which diffuses across the synapse. The transmitter substance binds with receptor molecules in the membrane of the next neurone.
