Savarese Ch 10: Facilitation Flashcards
What is facilitation?
The maintenance of a pool of neurons in a state of partial or sub-threshold excitation.
What are the 3 parts of a spinal reflex?
- An afferent limb –> Sensory input
- A central limb –> Spinal pathway (interneurons)
- An Efferent limb –> motor pathway
In facilitation, what is actually sensitized?
The interneurons at a spinal cord level.
Through which pathway does visceral dysfunction transmit information to the spinal cord?

Why should you know who Irvin Korr PhD was?
He established that there is HYPERSYMPATHETIC ACTIVITY in disease processes.
Therefore; it is important to curb sympathetic activity, or enhance parasympathetic activity when treating disease states.
What are the 5 OM techniques aimed at the sympathetic nervous system?
- Rib raising
- Soft tissue paraspinal inhibiton
- Celiac ganglion, Superior mesenteric, Inferrior mesenteric releases
- Tx of Chapman’s reflexes
- Tx of cervical paraspinal sympathetic ganglia
What are the 3 purposes of Rib Raising?
- Normalize (decrease) sympathetic activity
- Improve lymphatic return
- Encourages maximum inhalation and provokes a more effective negative intrathoracic pressure.
What are the indications of rib raising?
Visceral dysfunction Decreased rib excursion Lymphatic congestion Fever Paraspinal muscle spasm

Normalize (decrease) sympathetic activity
*Ileus prevention!)

resist the urge to insert joke
Aids in dural strains and improves parasympathetic function in head structures innervated by CN 3, 7, 9, 10.
What is the purpose of Sphenopalatine ganglion technique?
Enhancing parasympathetic activity will encourage thin watery secretions through short intermittently manual finger pressure intraorally to the sphenopalatine ganglion.
What is the indication (1) for sphenopalatine ganglion technique?
Thick nasal secretions
What is the purpose of Condylar decompression?
Help free parasympathetic responses to structures innervated by cranial nerves IX and X by freeing passage through the jugular foramen (i.e. occipito-mastoid suture)
Our profs say CNXII is primary here, FYI
Give a clinically significant scenario with condylar compression:
Can result from child birth - may cause suckling difficulties for the newborn and thus failure to thrive.
