Knowledge quiz

1. When our tissues are forcibly squashed or stretched (high supra-threshold stimulation) electrical impulses are triggered in specialised afferent nerves? These are conventionally called:

Laminae
Nociceptors
A-beta (ß) fibres
Golgi organs
the autonomic nervous system

2. Pain can come from the shoulder:

True

False

3. Only the assessing clinician can judge if someone has real pain:

True

False

4. Second-order neurones projecting from Lamina I are commonly called:

Wide-dynamic range neurones
Nociceptive-specific neurones
Inter-lamina neurones
A-delta and C-fibres
A-beta and A-alpha fibres

5. The medial nociceptive system (inc. medial thalamic nuclei) can be described as:

Slow and only broadly somatotopic
Fast and highly somatotopic
Slow and highly somatotopic
Fast and only broadly somatotopic
Highly sensory-discriminative

6. The best indication that a person is in pain is:

an experienced doctor says so
an experienced nurse says so
an experienced physiotherapist says so
an experienced psychologist says so
the person says so

7. Analgesics and transcutaneous electrical nerve stimulation (TENS) are similar in that they do not target the injured tissue but attempt to interfere with the nociceptive system:

True

False

8.    Normalisation of the representation of a body part in the primary somatosensory cortex (S1) can reduce pain. This can be achieved by:

Altering the firing properties in the brain
Visual attention to sensory stimulation of the affected body part
Improving tactile acuity
Training tactile discrimination
All of the above
