3.5 The Spinal Cord

Learning goals

I can....

• explain how reflexes are different than a normal nervous system response.
• follow the chain of events that take place during a reflex arc.
• explain how impulses are passed from one neuron to the next.
• explain the function of neurotransmitters in spreading impulses.
• describe how drugs can connect to receptors and disturb impulses.

Key words

• Reflexes 
• Spinal cord
• Synapses
• Vesicles
• Neurotransmitters

Reflexes

A reflex is also a response of your body, but then using your spinal cord as a coordinator instead of a your brain:

- this is often used in cases of emergency

Synapses

Synapses are connections in your nervous system that use chemicals in stead of electricity:

- synapses work with a chemical called neurotransmitters

- the bag that holds the neurotransmitter is called a vessicle
