Anaesthesia | Pain | Physiology of Pain Transmission



Physiology of Pain Transmission
Session Overview
Description
This session provides an overview of peripheral mechanisms of injury-induced and inflammatory pain. It includes a description of the physiology of nociception at the dorsal horn and supraspinal levels.
Learning Objectives
By the end of this session you will be able to:
- Explain why a warm shower feels burning hot on sunburned skin
- Explain how non-steroidal anti-inflammatory drugs act as analgesics
- Recognize the major mediators of inflammatory pain in the periphery
- Explain the role of sodium channels in nociception
- Explain how chilli peppers produce the sensation of heat
- List the major excitatory and inhibitory neurotransmitters involved in pain transmission at the dorsal horn
- Explain why the longer pain is left untreated, the harder it can be to control
- Describe the physiological response to pain
