Module 5: Pain assessment Flashcards
What is nociception?
Term used to describe how noxious stimuli are typically perceived as pain
Nociception can be divided into four phases. What are they?
Transduction, transmission, perception of pain, and modulation
In what stage of nociception is the conscious awareness of a painful sensation felt?
Third phase - Perception
What phase of nociception does the pain impulse move from the level of the spinal cord to the brain?
Transmission – 2nd phase
What phase of nociception is the pain message inhibited?
4th phase - modulation.
Pain is based on its origin, that is classified as
Nociceptive, neuropathic, or both
Nociceptive pain is caused by? Feels like? Further classified as?
Tissue injury. Well-localized and often described as aching or throbbing.
Further classified as somatic or visceral
Superficial somatic pain is derived from where? Deep somatic pain is derived from where?
Superficial - Skin surface and subcutaneous tissues
Deep- Joints, tendons, muscles, or bone
Visceral pain originates from
Larger interior organs (e.g., kidney, intestine, gallbladder, and pancreas)
Pain signals are carried to the central nervous system by way of
Afferent fibres
What occurs during transduction (first phase of nociceptive pain)?
Pain signals move from the site of origin to the spinal cord
Neuropathic pain implies an abnormal
Processing of the pain message
Specialized nerve endings that are designed to detect painful sensations
Nociceptors
