Synapses are an important part of the nervous system. What is a synapse? Describe how information passes through a synapse.

_{A synapse is a junction between neurones. Description of a synapse being a small gap between two neurones.} 

_{Synapses use chemical messengers to pass an impulse of electrical depolarisation from one neurone to the next. When the electrical depolarisation reaches the end of one neurone, chemical neurotransmitters are released into the synapse and bind with receptors on the post synaptic neurone, eliciting depolarisation of the second neurone.}
