Introduction to Facial Pain Flashcards
what is an example of nociceptive pain
putting your hand on a hot pan and withdrawal reflex
what are the three types of pain
nociceptive
inflammatory
pathological
what can cause non-odontogenic intra oral pain on mucosa
ulcers
lichen planus
vesiculobullous disease
salivary gland
what is pain
unpleasant sensory and emotional experience
potential for tissue damage
how do we assess a patient in pain
physical symptoms
emotional symptoms
QOL (quality of life) scores
what are the four ways we feel pain
nociception
peripheral nerve transmission
spinal modulation
central appreciation
how do cranial nerves communicate with the brain
the nucleus associated with the nerve
what are the somatic nerves linked to the head and neck
CN V, VII, IX, X
cervical 1-3
why are pain signals coming from the autonomic supply more distressing
they go to the basal part of the brain - which was one of the first parts of the brain to be formed
what is the somatic reflex ark
sensory neuron - branches with relay neuron in spinal cord which then branches with motor neurone
what is the autonomic reflex ark
afferent information going in
efferent signals going out
how are nociceptors activated
there is tissue damage which releases chemical mediators
what is the gate control of chronic pain
spinal cord modulates what pain goes to the brain
what is neuronal plasticity
chronic pain can trick the nerve to be hypersensitive so even when cause is removed there is still pain
what is learned pain
brain learns to expect pain
