Biology Study Set: DSA6 Reflexes & Facilitation Terms

What did Dr. Louisa Burns publish in 1948?

Pathogenesis of Visceral Disease from Vertebral Lesions

Why are appendicitis patients often found "doubled over" on their side?

Inflammation from appendix sends signals to T10 --> T10 then sends afferents out to send pain signals (tells CNS there's pain in RLQ and in the muscle under appendix, or Iliopsoas) --> causes lower back pain and muscle spasms

Dorsal Nerve Component (sensory)

Identify this portion of the nerve

Ventral Nerve Component (motor)

Identify this portion of the nerve

Sympathetic chain - give information straight into ganglia from nerve root; increases autonomic tone to organ/muscle in question AND sympathetic tone

Identify this portion of the nerve and its function

Facet Joints of Nerve - where some information from root gets sent UP and DOWN - when these get activated, the tissue around these joints become palpably different in texture

Identify this portion of the nerve and its function

Define Somatovisceral Reflex

Alteration in soma --> alteration of viscera (ex: Muscle tension --> vagus nerve irritation --> trigger for Nausea)

Define Viscerovisceral Reflex

Alteration in viscera --> alteration in other viscera (ex: Uterine contraction leading to Bowel dysfunction)

Define Somatosomatic Reflex

Alteration in soma --> alteration in other area of soma (ex: Diaphragm irritation leading to shoulder pain)

Define Crossed Extensor Reflex

Signals sent from agonist AND antagonists' spindles --> since very few interneurons in CNS, many signals come to same interneurons --> aggravation from one muscle can cause any of these few interneurons to fire --> synapse the neurons for maybe both soma and viscera connected (so you can't make the distinction of what's in pain)

Define the Theory of Facilitation

Previous injury of one area will be affected pain wise by an injury in a connected area
