This learning program is designed to introduce the physiology of pain. Pain is a broad term used to describe an experience that everyone can relate to and is the most common reason that patients seek medical attention. Pain is nevertheless a complex phenomenon. Different forms of pain not only involve distinct receptors and pathways, but can also be modulated by different physiological factors. This program describes the different types of pain and how they are distinguished physiologically. A basic understanding of how pain is sensed, transmitted and perceived, and which aspects of physiology modulate pain is provided.
Upon completion of this learning program, you will be able to::
Contrast fast-sharp pain with slow-chronic pain.
List the 3 types of pain stimuli that activate pain receptors.
Compare the 2 pathways for transmission of pain signals.
Describe how pain is enhanced or suppressed by pain modulation pathways.
