Question 13

Spinal facilitation is the maintenance of a pool of neurons in what state?

Results in?

Answer 13

• A state of partial or subthreshold excitation
• In this state, less afferent stimulation is required to trigger the discharge of impulses

Question 14

Spinal facilitation may be due to sustained increase in what 3 factors?

Answer 14

• Afferent input
• Aberrant patterns of afferent input
• Changes within the affected neurons themselves or their chemical enviornement

Question 15

Answer 15

• Rib-raising
• Paraspinal inhibition
• Cervical ganglia inhibition
• Abdominal collateral ganglia technique
• Target non-neutral (type II) SD if present

Question 16

6 OMT techniques which can be used to normalize parasympathetic tone?

Answer 16

• Suboccipital inhibition
• Sphenopalatine ganglia release
• Sacral inhibition and rocking
• Sacroiliac joint gapping
• BLT
• Gentle ME

Question 17

What did Louisa Burns do?

Answer 17

• Induced SD of the atlas, C6, and T3 in rabbits
• Measured pulse (rate and amplitude); respons to exercise; EKG and tissue samples

Question 18

In rabbits with induced SD of the Atlast what was seen 2 months later?

Answer 18

• Developed arrhythmias
• Theorized to be result of vagal nerve facilitation
