Autonomic Nervous System and Sensory Systems Flashcards
What is the job of the hypothalamus?
initiation of motor activity for meeting homeostasis needs, autonomic functions
What are other structures in the autonomic nervous system?
olfactory cortex- smell
hippocampus- memory
amygdala- emotion
What is the effect of the limbic system?
reciprocal connections which have an effect on arousal, participation, learning and compliance
What is the role of the autonomic nervous system?
controls activity of smooth muscle, cardiac muscle and glands, visceral activity
balance of sympathetic and parasympathetic- homeostasis
What three systems are required for survival?
ANS, sensorimotor system, limbic system
What is role of sympathetic nervous system?
hyper vigilant, “fight or flight” , vitals increase, sweating, increase blood flow to muscles , increase in glucose production
What is role of parasympathetic system?
decreased awareness of environment, vitals decrease, increase blood to GI and relaxation of muscles
Why is it important to know the signs of sympathetic nervous system?
changes in ANS could be related to underlying health condition, need to modify treatment area
What are some techniques for decreasing sympathetic nervous response?
slow continual stroking of paravertebrals for 3-5 minutes, slow pain free PROM/AAROM, deep breathing
What is the auditory system connected to?
vestibular system CN 8, auditory stimulation may cause problems with equilibrium
Where is the auditory cortex located?
temporal lobe, which is responsible for ability to hear/process verbal commands
How does voice volume and quality affect ANS?
soft steady sounds will calm
loud fluctuating tone will increase arousal
extraneous noise may cause agitation
Where is the visual cortex located?
occipital lobe , ability to perceive visual stimuli, detect our movement and orientation of body parts in space
What is the connection between visual system and rest of body?
impact of muscle tone, balance, emotion, level of arosual
What are two ways to alter ANS through vestibular system?
slow sustained movements- decreases ms tone, calming (otoliths)
fast arrhymitcial- increases tone, arousal level and motor response (can help with someone with low tone)
What are exteroreceptors?
tacticle receptors that are part of the spinothalamic system
primitive, protective resposnes for pain
pleasure inresponse to light touch
What is the lemniscal system?
discrimination of touch , pressure, location, contour, spatial details and quality of somatic stimuli
What is perceived as less painful, light or firm touch?
sustained firmer touch
How do you facilitate exterorecptors?
light touch, quick stroking
inihibit- slow stroking, sustained
What are three kinds of proprioceptors?
muscle spindle, golgi tendon organ, joint receptors
What does joint distraction facilitate?
agonist flexor group
What does joint approximation facilitate?
postural extensors, co contraction for increased stability
