Neurological Reflexes Flashcards
What is a somato-visceral reflex?
The neuromusculoskeletal system’s effect on an organ
If acute low back pain and spasms cause the lower intestine to spasm and cause constipation, what type of reflex is occurring?
Somato-visceral reflex
How does a somato-visceral reflex function?
Nociception arising from MSK structure triggers activity of autonomics that can affect input to visceral structures
What is a viscero-somatic reflex?
Visceral disturbance resulting in increased musculoskeletal tension in structures innervating corresponding levels
There’s a long history that spinal tenderness can be a sign of…
an underlying visceral condition
A visceral disorder may “hide” or present as…
an MSK disorder
Give an example of a classic visceral referred pain pattern
Gallbladder dysfunction referring to the right scap/shoulder region
Not reproducible, constant, unremitting pain could be due to…
underlying visceral condition
If pain occurs primarily at night, it could be due to…
underlying visceral condition
Fever or chills, unexplained weight loss, and change in bowel or bladder habits could all be due to…
underlying visceral condition
What is a somato-somatic reflex?
Reflex patterns between two somatic structures
Nociception from bone, ligament, joints, fascia, etc. may create a reflex response in muscle fibers that result in tightness and pain
What kind of reflex is this?
Somato-somatic reflex
What is a viscero-visceral reflex?
Visceral stimulus producing reflex activity in segmentally related visceral structures
Post-surgery on a visceral structure, afferent neuron activity from visceral structure involved may stimulate efferent autonomic (sympathetic) activity which may result in an undesirable immobilization of intestines
What kind of reflex is this?
Viscero-visceral reflex
What is a classic, but not fully correct, example of a psycho-visceral reflex?
Stress relating to ulcers
Ulcers are now known to be caused by H. pylori infection and long-term NSAID use
