---|---|---|---|---|
1 | Receptors on nerves work by opening ion channels (gates) in the wall of the nerve | |||
2 | When part of your body is injured, special pain receptors convey the pain message to your brain. | |||
3 | Pain only occurs when you are injured. | |||
4 | The timing and intensity of pain matches the timing and number of signals in nociceptors (dangerreceptors) | |||
5 | Nerves have to connect a body part to your brain in order for that body part to be in pain | |||
6 | In chronic pain, the central nervous system becomes more sensitive to nociception (dangermessages) | |||
7 | The body tells the brain when it is in pain | |||
8 | The brain sends messages down your spinal cord that can increase the nociception (danger message) going up your spinal cord. | |||
9 | The brain decides when you will experience pain | |||
10 | Nerves adapt by increasing their resting level of excitement. | |||
11 | Chronic pain means that an injury hasn’t healed properly. | |||
12 | Nerves can adapt by making more ion channels (gates) | |||
13 | Worse injuries always result in worse pain | |||
14 | Nerves adapt by making ion channels (gates) stay open longer | |||
15 | Second-order nociceptor (messenger nerve) post-synaptic membrane potential is dependent on descending modulation | |||
16 | When you are injured, the environment that you are in will not have an effect on the amount of pain you experience. | |||
17 | It is possible to have pain and not know about it. | |||
18 | When you are injured, chemicals in your tissue can make nerves more sensitive | |||
19 | In chronic pain, chemicals associated with stress can directly activate nociception pathways (dangermessenger nerves). |
