Q

somatosomatic

A

reflexes whose afferents and efferents are somatic nerve fibers
stimulus at one level of muscukoskeletal system produces relfex activity in the nervous system, which is then exhibited elsewhere in the musculoskeletal system

viscerosomatic
relfexes whose afferents are visceral sensory fibers and whose efferents are somatic motor nerve fibers
26
example of viscerosomatic
respiratory or digestive dysfunction such as asthma or colic may cause reflex disturbances in the spine leading to muscle tension and joint subluxation
27
somatic
refers to skin, bone muscle or nerve
28
visceral (autonomic)
organs, blood, lymph
29
psycho
thinking about something
30
where does the gate theory of control occur?
substantia gelatinosa
31
what does the degree of opening/closedness of the gate depend on?
the spinal cord
32
type A beta afferent fibers
greatly depress (inhibit) the pain that travels on type C and A delta fibers
33
pain fibers terminate where?
dorsal horn of spinal cord in substantia gelatinosa
34
when in the substantia gelatinosa, when mechanoreceptor axons terminate, what does that cause?
pretynaptic inhibition
35
vertebrobasilar arterial insufficiency hypothesis
cervical intervertebral subluxations may cause deflection or compression of the vertebral arteries, which alters cerebral circulation
36
symptoms of VBAI
``` 5Ds and 3Ns diploplia dizziness drop attacks dysarthria dysphagia ataxia of gait nausea numbness on one side of the face/body nystagmus ```
37
most common location for compression of the certebral artery is?
over the posterior arch of C1
38
what causes the most compression to the vertebral artery?
rotation and extension of C1 and C2
39
what is considered the significant neuologic disorder accompanying vertebral subluxations?
spinal nerve root compression | axoplasmic transport
40
how were spinal subluxations hypothesized to induce NR compression?
as a result of direct anatomic compression of neural elements within the IVF
41
what predisposes someone to NR compression
degenerative changes of the bony structures in the IVF
42
bone on nerve causes what?
pain in dermatomal patterns decreased DTR paresthesia muscle atrophy
43
what do the nerve rootlets lack?
epineural covering of the NRs as they exit the IVF
44
what are the nerve rootlets more susceptible to?
pressure inflammation ischemia
45
what lies within the IVF?
DRG
46
axoplasmic transport
non-impulse mechanism based not on transmission of signals along the surface of the neuron but rather on the intra-axonal transport and exchange of macromolecular materials
47
trophic substances
chemicals transported by axoplasmic transport
48
what is essential for maintenance of proper tissue function
trophic substances
49
what does trophic function influence
the development and maintenance of chemiccal changes in cells supplied by the nerve
50
describe how the chemicals move in axoplasmic flow
carried the full length of the axon to the terminals, after which materials from the terminals are returned to the cell body for reprocessing
51
is axoplasmic flow slow or fast?
slow
52
anterograde axoplasmic transport
forward moving cell body to terminal nerve growth (troophic) faster more common
53
retrograde axoplasmic flow
backward moving brings products/wastes to cell body slower less common
54
clinical implications of axoplasmic transport
any factor causing derangement of transport mechanisms in the axon could cause trophic influences to become detrimental
55
alteraltions in axoplasmic transport produce what?
aberrations of structure, function and metabolism | contributes to dysfunction and disease
56
compressive myelopathy/cord comrpession refers to?
descruction of spinal cord tissue caused by pressure from neoplasms, hematomas, congenital defects, extreme trauma
57
facilitation hypothesis AKAs
``` fixation theory segmental facilitation segmental hypothesis gamma motor gain proprioceptive insult sympatheticotonia ```
58
segmental facilitation
lowered threshold for firing in a spinal cord segment as a result of afferent bombardment associated with spinal lesions
59
Korr focused on muscle spindles as what?
coordinator that may increase or decrease muscle contraction according to the direction of motion of the joint
60
facilitation
continuous firing of nociception makes it easier to get to the brain
61
propriceptive insult
constant bombardment of nociception lowers the threshold for firing in the segment
62
Korr explained that a vertebra could be "stuck", but also have normal range of motion, why?
due to muscle spasm producing hypomobility and nociception
63
neurodystrophic hypothesis
spinal biomechanical insult to nerves may affect intra-neural axoplasmic transport mechanisms and, in turn, affect the quality of neurotrophic influence and molecular (chemical) changes in cells
64
neural dysfunction causes lowered tissue resistance, which does what?
modified the immune responses and alter the trophic function of the inolved nerves
65
general adaptation syndrome
exposure under optimum conditions, the body can respond to various stressors by adapting to them
66
distress
negative stress
67
eustress
positive stress
68
hypothalamic-pituitary-adrenal axis system
system whereby the body copes with stress
69
stages of adaptation
alarm resist adapt exhaust
70
alarm stage
upon encoutering a stressor, body reacts with fight or flight response and sympathetic nervous system is acvivated hormones such as cortisol and adrenalin released into the blood stream to meet the threat or danger body's resources are mobilized
71
resistance
parasympathetic NS returns many physiological function to normal levels while body focuses resources against the stressor blood glucose levels remain high, cortisol and adrenalin continue to circulate at elevated levels, but outward appearance of organism seems normal increase HR, BP, breathing body remains on red alert
72
exhaustion
stressor continues behond body's capasity, organsim exhausts resources and becomes susceptible to disease and death
73
response to stress is coordinated by?
neuroendocrine mechanism
