Synapses

• What is a synapse?

  The gap between two neurons
• What happens at a synapse?

  Chemical signals (neurotransmitters) are released
• What is released from the axon terminal of a neuron at the synapse?

  Neurotransmitters
• How do neurotransmitters affect the next neuron in the synapse?

  They bind to receptors, causing an electrical impulse
• What type of signal is transmitted across a synapse?

  Chemical
• How is the electrical impulse transmitted across the synapse?

  By neurotransmitters being released and binding
• What happens if neurotransmitters are not released properly at a synapse?

  The electrical impulse may not be transmitted
• Which of the following is a function of synapses in the nervous system?

  To transmit impulses from one neuron to another
• What is the role of receptors on the post-synaptic neuron?

  To receive neurotransmitters and trigger a response
• What happens after neurotransmitters bind to receptors on the post-synaptic neuron?

  The post-synaptic neuron is stimulated to generate an electrical impulse
