Solved 100% Correct
__________ are receptors that receive sensory input from the body's musculoskeletal
system - Answer proprioceptors
Proprioceptors provide the body with information regarding: (3) - Answer 1. presence
2. position
3. movement
5 examples of proprioceptors and their functions: - Answer 1. Muscle spindles: stretch
2. Golgi tendon organs: tension
3. Pacinian corpuscles: pressure
4. Periodontal mechanoreceptors
5. Free nerve endings: pain
__________ are receptors that receive sensory input from the body's "supply system" -
Answer interoceptors
2 examples of interoceptors and their functions: - Answer 1. Pacinian corpuscles:
pressure
2. Free nerve endings: pain
Which type of receptors provide information that can be sensed at a conscious level? -
Answer exteroceptors
,sometimes proprioceptors (chiefly unconscious)
Which type of receptors provide information that is sensed at an unconscious level? -
Answer interoceptors
sometimes proprioceptors (chiefly unconscious)
Pain from which type of receptors generally stimulate action from the individual? Which
inhibit action? - Answer stimulate = exteroceptors
inhibit = proprioceptors and interoceptors
The ______________ is the part of the sensory cortex devoted solely to sensory input
from the face - Answer Homunculus
3 functions inhibitied by orofacial pain that make it particularly significant: - Answer 1.
chewing
2. speaking
3. non verbal expression
The _____________ Theory states that all individuals perceive pain sensation at the
same level of noxious stimulation, and the great variation of pain experiences is related
to the individual's reaction to the pain sensation - Answer Pain Perception-Reaction
The ____________ Theory focused on a reexamination of pain mechanisms, particularly
an inhibitory interneuron - Answer Gate-Control
, The concept of ___________ states that a descending inhibitory system acts to counter-
balance the ascending arousal system - Answer Pain Modulation
3 premises of the "Dynamic Nervous System" which contribute to the concept of pain
modulation: - Answer 1. no stimulus arrives in a blank open CNS
2. all peripheral stimuli interact as the enter the CNS
3. all known central transmission pathways are subject to powerful controls and
modulations
Within the concept of pain modulation, constant sensory input from the ____________
initiates a tonic, low-level background of impulses that represent the arousal system -
Answer dorsal root ganglion
Within the concept of pain modulation, a ___________ system acts to counter-balance
the tonic, low-level background of impulses that represent the arousal system - Answer
Descending inhibitory system
4 important functions allowed by the actions of the descending inhibitory system: -
Answer 1. selective attention
2. concentration
3. sleep
4. pain modulation
3 known mechanisms of pain modulation: - Answer 1. nonpainful, cutaneous
mechanisms (warm rag, music, etc)
2. intermittent, painful stimulation (acupuncture)
3. psychological modulation mechanisms (excitatory or inhibitory)
