Block 2 #3 Flashcards
What is the primary goal of a neurological exam?
Localize problem
What are the 6 steps to a neurological exam?
Mental status
Gait and posture
Postural reactions
Cranial nerve exam
Spinal reflexes
Pain and sensation
What goes into the mental status exam?
Level of conciousness (brainstem)
Behavior (forebrain)
What is kyphosis?
Back bending up
What is lordosis?
Back bending down
What does the gait exam take into consideration?
Literally everything
What are the 3 key questions to gait exams?
Is the gait normal/abnormal
If abnormal, where is it abnormal
What is the problem

tetra
What is paresis of just pelvic?
Para
What is paresis of one side?
Hemi
What is paresis of a single limb?
Mono
What is vestibular ataxia?
Head tilt
What is cerebellar ataxia?
Dysmetria (hypermetria), tremors
What does hypermetria mean?
High stepping
What does ataxia mean?
Incoordination
What are the 3 types of ataxia?
Vestibular
Cerebellar
Proprioceptive
What is something you need to do during the menace response?
Cover the opposite eye
What cranial nerve does the menace response test?
II - optic
What cranial nerve does the pupillary response test?
III - oculomotor
What cranial nerve does the palpebral test?
V - Trigeminal
What branches of the trigeminal does the palpebral test?
Ophthalmic (most rostral)
Maxillary
Mandibulary (most caudal)
What is the nasal sensation test for?
Sensory for trigeminal but tailored toward cortex
How is CN VII tested?
Looking at symmetry
What CN does menace test?
II and VII
Thalamocortex and cerebellum
What CN does symmetry pupils and PLR test?
II and III (parasympathetic)
***What CN does palpebral test?
V and VII
What CN does nasal sensation test?
CN V
Which nerve closes eyelids?
Facial VII!
Is it menace response or reflex?
Response
Why is it menace response? (not reflex?)
It has cortical involvement
***What are the structures involved in the menace response?
CN II, VII, thalamocortex (motor and occipital), cerebellum
What parts of the thalamocortex are involved in the menace response?
Motor and occipital
What does a vertical (up and down) nystagmus indicate?
Central vestivular disease
(Brainstem, cerebellum)
What are 3 tests for trigeminal nerve?
palpebral reflex (3 branches)
Nasal sensation (*thalamocortex)
Muscles of mastication
What is most important part of neurological exam?
Gait exam
What does the cranial nerve tests test?
II - VIII
What is the knucking exam called?
Postural reactions (PRs)
What is the only part of the brain that the postural reaction does not test?
cerebellum
What is reflex?
Local
What is response?
Need cortex
Where does the pudendal nerve go to?
Anus
What is the spinal reflex?
Pinching of cutaneous truci cranially
**What does EFF stand for?
Extension femoral first
**What does SSF stand for?
Sciatic second flexion
What are the femoral segments?
L4-L6
What are the sciatic segments?
L6-S2
When a spinal reflex cutoff is found, where is the lesion?
Likely 2 vertebral bodies cranial
What does increased extensor tone mean?
Lesion in UMN (stiff leg)

Lesion in LMN (flaccid)
What are the UMN segments of spinal chord?
C1-5
T3-L3
What are the LMN segments of spinal chord?
C6-T2
L4-S3
What does a head turn (not tilt) indicate?
Forebrain/cortical lesion
