Exams, Muscle Strength, Reflexes Flashcards
when a primary sensory modality isn’t working the deficit is referred to as
anesthesia or analgesia
2 types of sensation
superficial and deep
types of superficial sensation
pain, temperature, light touch
pain, temperature, light touch carried in this tract
anterolateral part of cord
types of deep sensation
pain, touch, proprioception
pain, touch, proprioception carried in this tract
posterior part of cord
when checking the dermatomes, 2 other tests that can be performed are
deep tendon reflexes and muscle strength testing
light touch receptors
tactile disc of merkel
deep touch receptors
corpuscles of meissner
pain impulses travel along these types of fibers
A delta and C fibers
term designating areas insensitive to pain
analgesia
term designating areas having decreased sensitivity to pain
hypalgesia
term designating areas having increased sensitivity to pain
hyperalgesia
temperature of cold stimuli
41-50 degrees
temperature of hot stimuli
104-113 degrees
easiest and best way of checking motor nerve function
muscle testing
voluntary motor impulses initiated in this part of brain
cerebral motor cortex
the 3 areas of muscle integrity that are assessed
strength, tone, volume
0/5 muscle strength
no movement of muscle; 0% of normal movement
1/5 muscle strength
a twitch of movement; 0-10% of normal movement
2/5 muscle strength
moderate to severe paresis; 11-25% of normal movement
3/5 muscle strength
moderate paresis; 26-50% of normal movement
4/5 muscle strength
mild paresis; 51-75% of normal movement
5/5 muscle strength
normal; 76-100%
supraspinatus: segmental innervation and peripheral nerve
innervation: C4/5/6 (mostly C5)
nerve: suprascapular
deltoid: segmental innervation and peripheral nerve
innervation: C5/6 (mostly C5)
nerve: axillary
biceps: segmental innervation and peripheral nerve
innervation: C5/6
nerve: musculocutaneous
brachioradialis: segmental innervation and peripheral nerve
innervation: C5/6
nerve: radial
