Exam 2 Cervical Spine Part 3 Flashcards
T/F: Facet mechanoreceptors are responsive to extremes rather than mid-range of joint motion.
True
T/F: Muscles in the cervical region contation a high density of muscle spindles, especially suboccipital muscles.
True
What theory states that proprioceptive inout flowing into the dorsal horn serves to disallow or modulate nociceptive input into the CNS?
Gate Theory
What is the term for a change in the stimulus-response profile of dorsal horn neurons so that they respond to mechanoreceptive afferents as if they were nociceptors, meaning that hurt may not equal harm?
Sensitization
T/F: Adjustments to decrease nociceptor input to the spinal cord do not seem to be an effective way to decrease the “hyperexcitable central state.”
False; do seem to be effective
What changes have been seen via MRI studies between the suboccipital muscles of healthy individuals and those with chronic neck pain?
atrophy and Fatty infiltration/degreneration
When does the cervical curvature begin to develop?
prior to birth
T/F: Cervical kyphosis aids in absorbing spinal loads.
False; cervical LORDOSIS
What bones make up the “Upper Cervical Curve?”
“Lower Cervical Curve?”
occiput to axis (Kyphotic)
C2-C7 (Lordotic)
What should the angle of the cervical lordosis be when measured via lines through C1 and C7?
30-45 degrees
According to Deed Harrison (CBP), is Kyphosis a normal variant?
No
What did Lennon find was associated with pain and a myriad of autonomic dysfunctions?
kyphotic confidurations
What did Nagasawa find associated with tension headaches?
straightened or reversed cervical curves
How did Breig document a mulititude of successes in improving neurological disorders?
surgically inducing a lordosis
What is the primary load on the cervical spine?
compression
