PCOL ANALGESICS PART 1

An unpleasant sensory and emotional experience associated with actual or potential tissue damage

• PAIN

• PERCEPTION

• MODULATION

• TRANSDUCTION

is a painful condition that arise because of viral infection caused by Varicella zoster virus

• Shingles Pain

• Postherpetic neuralgia

• both

• none

The first step leading to pain is the activation of _____

• nociceptors

• receptors

• stimuli

• all of the above

External stimuli are converted to electrical signals that can be perceived as pain

• TRANSDUCTION

• TRANSMISSION

• MODULATION

• PERCEPTION

Message is carried from the site of tissue injury to the brain regions underlying perception (afferent neurons)

• TRANSDUCTION

• TRANSMISSION

• MODULATION

• PERCEPTION

Pain reaches the brain through ascending fiber tracts.

• TRANSDUCTION

• TRANSMISSION

• MODULATION

• PERCEPTION

The spinothalamic tract is divided into two ascending  pathways:

• Lateral

• Ventral

• Central

• Horizontal

the pain signal carried is sharp and localized pain

• Lateral Pathway

• Ventral Pathway

when neurons carries electrical messages wherein it originates from aching or dull or non-localized pain

• Lateral Pathway

• Ventral Pathway

The body alters a pain signal as it is transmitted along the pain pathway and explains, at least in part, why individual responses to the same painful stimulus sometimes differ. can either inhibit or facilitate pain

• TRANSDUCTION

• TRANSMISSION

• MODULATION

• PERCEPTION
