Transduction: What are nociceptors?
They are at the end of the peripheral nerves which are specialized receptors.
Transduction: What do nociceptors become activated?
When they are exposed to noxious stimuli. They can be mechanical, chemical, or thermal
Transduction: Mechanical stimuli may include?
Intense pressure to an area, strong muscular contractions, or extensive pressure due to muscular overstretching
Transduction: Chemical stimulation may involve?
Release of mediators such as histamine, prostaglandings, or bradykinin as repsonse to tissue traumaa
Tranmission: What is this?
When the stimuli are converted to electrical impulses which are relayed along peripheral nerves to the spinal cord and brain
Tranmission: Pain transmitted by these fibers often referred to as fast pain, which is associated with
mechanical or thermal stimuli , which is due to A-delta fibers
Tranmission: What do unmyelinated small C fibers do?
Transmit the impulse slowly and are often activated by chemical stimuli or continued mechanical or thermal stimuli
Tranmission: What is the gate-control theory?
Dorsal horn of spinal cord contains interneuronal or interconnecting fibers. Large fibers when stimulated close the gate or pathway to the brain, inhibiting transmission of pain impulse
Perception: What happes here?
Nerve fibers divide then cross to the opposite side toward the thalamus.
Perception: Impulse carried by a fast-A give what perceptions of pain?
Sharp, stabbing localized pain that is commonly involves the reflex xresposne to withdraw from stimulus
Perception: Impulse carried by slow-c fibers give what perceptions of pain?
Diffuse, dull, burning, or aching pain.
Perception: What is pain threshold?
The point at which the person first feels the lowest intensity of painful stimulus
Modulation: What do neuromodulators do?
Modify the pain sensation. Substance shave been found to change persons perception of pain. This includes serotonin
Modulation: How can pain perception be modified peripherally?
In peripheral nerve fibers, chemical susbtances are release that either sitmulate the nerve fibers or sensitize them. Allows nerve fibers to react to stimulis that is lower intensity
Types of Pain - Acute Pain: What is this?
Pain that is associated with a rapid onset of varying intensity. Usually indicates tissue damage and resolves with healing
Types of Pain - Acute Pain: Acute pain reflects stimulation of what?
Nociceptors and serves a protective function .
Types of Pain - Chronic Pain: What is this?
Defined as pain that continues past the expected point of healing for injured tissue.
Types of Pain - Chronic Pain: Chronic, recurrnet pain is most commonly associated with?
Abdominal pain, nonspecific headache and limb pain.
Types of Pain - Nociceptive Pain: This reflects pain due to what?
Nixous stimuli that damages normal tissues or has potential to do so if prolonged. Ranges from sharm or burning to dull and aching.
Types of Pain - Nociceptive Pain: Examples that cause this?
Chemical burns, sunburn, cuts, appendicits and bladder distention
Types of Pain - Neuropathic Pain: Pain is due to what?
Malfunctioning of the peripehral or CNS.
Types of Pain - Neuropathic Pain: How is this described?
Burning, tingling, shooting, sqeezizng, or spasm-like pain.
Types of Pain - Neuropathic Pain: Examples of this include?
Posttraumatic and postsurgical peripheral nerve injuries, pain after spinal card, and phantom limb pain
Types of Pain - Somatic Pain: What is this?
Pain that develops in the tissues.
