Acute Pain 2 Flashcards
What receptors detect pain
Nociceptors
What activates the nociceptors
Damage to tissue
What NS do pain fibres have to go through first in the pain matrix
The spinal cord
What Tract does the spinal cord send pain fibres/signals to in the pain matrix
The contralateral Spinothalamic tract
What is the contralateral spinothalamic tracts’s role in the pain matrix
Receive pain fibres/signals from the spinal cord and send them to either the periaqueductal grey area
Where is slow pain sent to from the contralateral Spinothalamic tract in the pain matrix
The periaqueductal grey area
What is the periaqueductal grey area
It’s apart of the pain matrix and receives slow pain signals
Where does the contralateral Spinothalamic tract send fast pain signals/fibers in the pain matrix
The thalamus
What tract does the thalamus receive pain signals from
The contralateral Spinothalamic tract
What are the 2 parts of the thalamus that receive pain signals/fibers
Medial and lateral
Where are the medial and lateral divisions apart of in the pain matrix
The thalamus
What division of the thalamus sends pain signals to the somatosensory cortex
The lateral division
Where does the lateral division send pain signals to in the pain matrix
The somatosensory cortex
What does the somatosensory cortex do in the pain matrix
Localises pain
What Part of the pain matrix localises pain
The somatosensory cortex
What are the two cortex’s the medial division sends pain signals/fibres to
Anterior cingulate cortex & the frontal cortex
What division of the thalamus sends pain Signals/fibres to the anterior cingulate and the frontal cortex
The medial
What is the anterior cingulate cortex’s role in the pain matrix
To select a response to the pain through emotions, memory and attention
What part of the pain matrix selects a response to the pain through emotions, memory and attention
The anterior cingulate cortex
What role does the frontal cortex play in the pain matrix
It’s creates the motors response to pain
What creates the motor response to pain in the pain matrix
Frontal cortex
What is the insula in the pain matrix
Works out the worth/value of pain
What part of the pain matrix Works out the worth/value of pain
The insula
