QUESTIONS AND VERIFIED ANSWERS||
GRADED A+|| LATEST UPDATE!!
Apraxia -CORRECTANSWER inability to make a motor plan, as a result of brain
damage.
Ataxia -CORRECTANSWER lack of muscle coordination
Aphasia -CORRECTANSWER impairment of language, usually caused by left
hemisphere damage either to Broca's area (impairing speaking) or to Wernicke's area
(impairing understanding).
1 olfactory -CORRECTANSWER Making client smell something pleasant
front of brain
2 optic -CORRECTANSWER thalamus - test visual acuity (Snellen chart, or # of fingers)
front of brain
3 Oculomotor -CORRECTANSWER thalamus - looking up, in and left to right
,midbrain
4 Trochlear -CORRECTANSWER midbrain - cross eyes into nose
5. Trigeminal -CORRECTANSWER pons - - Dull vs light sensation in: Opthalmic
(forehead) Maxillary (Cheek)Mandibular (Jawline)
- Have the patient open and close mouth (feel around temporomandibular joint)
6 Abducens -CORRECTANSWER pons- looking laterally (left and right)
7 Facial -CORRECTANSWER controls most facial expressions
secretion of tears & saliva
taste
pons - Test facial symmetry - Taste on anterior 2/3 of tongue - smile - wrinkle forehead
8 Vestibulocochlear -CORRECTANSWER hearing and equilibrium
pons (acoustic) - Whisper test - Rinne Test - Weber Test
9 Glossopharyngeal -CORRECTANSWER medulla - Gag reflex- Taste on posterior 1/3
of the tongue - not gagging is a sign of lesion
, 10 Vagus -CORRECTANSWER medulla - - Say "aah" - Talk to see if uvula deviates to
one side
11 Spinal Accessory -CORRECTANSWER controls trapezius & sternocleidomastoid
controls swallowing movements
spinal cord - shoulder shrug against resistance
medulla
12 Hypoglossal -CORRECTANSWER medulla - stick tongue straight out - will deviate if
there is a lesion
Somatosensory pathways - Posterior column pathways: Proprioception, vibration, fine
touch -CORRECTANSWER Primary afferent sensory information is coming in from the
dorsal roots then travels to the ipsilateral white matter columns and ascends all the way
to dorsal column nuclei in the medulla then it will synapse onto a second sensory
neuron that crosses over to the other side of the medulla and that axon will continue to
ascend now on the contralateral synapse on the thalamus will then project up to the
primary somatosensory cortex.
Somatosensory pathways- Anterolateral pathways: Pain and Temperature -
CORRECTANSWER Sensory information comes in through dorsal root ganglia to the
