Trochlear Nerve (motor) - controls superior oblique muscle - moves eye down, or back and forth (side to side)
27
Cranial Nerve V
Trigeminal Nerve (sensory and motor) - Ophthalmic: sends sensory info to upper face (forehead, scalp) - Maxillary: sends sensory info to middle of face (cheeks, upper lip, nasal cavity) - Mandibular: (both motor and sensory) sends sensory info to lower face and moves jaw and ear - Sensations in your face and cheeks, taste and jaw movements
28
Cranial Nerve VI
Abducens Nerve (motor nerve) - controls the lateral rectus muscle - ability to move your eyes
29
Cranial Nerve VII
Facial nerve (sensory and motor) - facial expressions and sense of taste
30

33
Cranial Nerve XI
Accessory Nerve (motor) - shoulder and neck muscle movement
34
Cranial Nerve XII

35
What is mental status ?
the degree of competence that a person shows in intellectual, emotional, psychological and personality functioning
36
What questions do we ask to ensure the patient is alert and oriented ?
- For client's name (last orientation to be lost) - Where he or she is (second orientation to be lost) - Ask the date (first orientation to be lost) - what is happening (situation)
37
Lethargic
aroused by saying their name and touching them - once aroused they respond appropriately but return to "sleep" once stimuli cease
38
Obtunded
require louder verbal stimuli and vigorous shaking to prompt a response - they carry out requests while awake but return to "sleep" when stimuli ceases
39
Stuporous
require painful stimuli to respond - response is usually withdrawal from pain
40
Semicomatose
require painful stimuli and respond with abnormal flexion or extention
41
Comatose
does not respond to any stimuli, even central pain
42
What is the test we perform for balance ?
Romberg test
43
What determines consciousness ?
awareness, arousal, and cognition
44
What is the scale of the Deep Tendon Reflexes ?
0: no response 1+: sluggish or diminished 2+: active or expected response (normal) 3+: more brisk than expected, slightly hyperactive 4+: brisk, hyperactive, with intermittent or transient clonus
45
What is clonus ?
involuntary, rhythmic muscular contractions and relaxations
46
What are some reasons for hyperactive reflexes ?
- spinal cord injuries - calcium and magnesium deficits - hyperthyroidism
47
What are some reasons for diminished reflexes ?
- calcium or magnesium excesses - hypothyroidism - spina bifida - guillain barre syndrome
48
What does a positive babinski look like ?
the big toes bends up and the other toes fan out - normal in kids younger than 2 yrs old
49
Aphasia
defective, or absent, language function
50
Dysphagia
difficulty swallowing
51
Receptive/Fluent Aphasia
inability to comprehend the speech of others, spoken words are logical - Wernicke's Asphasia: temporal lobe
52
Expressive/Non-Fluent Aphasia
inability to communicate or express ideas as meaningful speech
53
Dysphasia
speech impairment
54
What does a normal/negative babinski look like ?
toes curl down (flex) - normal in kids older than 2 yrs old
55
What is the expected age range for the Moro Reflex ?
- birth to 1-4 months
56
Tonic Neck Reflex
- birth/6 wks to 4-6 months - move head to side with arm/leg extended - they will extend on the side where their head is turned and the opposite side is flexed
57
What are abnormal findings in toddlers and children ?
- spasticity - paralysis - impaired vision, speech or hearing - inattention, motor restlessness and easy distractibility may indicate ADHD
58
What are expected findings in older adults ?
- slowed responses - move more slowly - decline in function - deviation of gait from midline - difficulty with rapidly alternating movements - some loss of reflexes and sensation
59
What are abnormal findings in older adults ?
- resting tremor of the hands that is reduced with purposeful movement - dizziness or vertigo - hemiparesis of upper or lower extremities (weakness/mild loss of strength)
60
What is Multiple Sclerosis ?
progressive demyelination of nerve fibers of brain and spinal cord - typical onset between 20-50 yrs; higher risk among women - clinical findings depend on the area of affected CNS Symptoms: - fatigue - depression - paresthesia - ocular changes - gait instability - bowel/bladder dysfunction
61
What are Spinal Cord Injuries (SCI) ?
caused by traumatic disruption of spinal cord - Cervical SCI: quadriplegia, tetraplegia - Thoracic and Lumbar SCI: paraplegia - Clinical Findings: complete SCI vs incomplete SCI
62
What are Head Injuries ?
in injury or trauma to the scalp, skull, or brain - Open Head Injury: d/t fractures or penetrating wounds - Closed Head Injury: d/t blunt trauma (concussion or confusion) - Clinical Findings: depend on severity of the trauma and areas of brain involved
63
What is Parkinson Disease ?
a chronic, progressive movement disorder - results from degeneration of dopamine-producing neurons
64
What is a Cerebrovascular Accident (Stroke) ?
occurs when brain cells die from ischemia - results from thrombus, embolus, or hemorrhage - clinical findings vary depending on area of the brain involved and extend of ischemic area Symptoms: - motor impairments - bowel and bladder dysfunction - speech and swallowing difficulties
65
What is the acronym for Cerebrovascular Accident (stroke) ?
ACT FAST - facial drooping - arm weakness - speech difficulty - time to call 911
66
What is one of the earliest and most sensitive indictors in alternations in cerebral function ?
change in LOC
67
What is 2-point discrimination ?
touch with 2 points; patient states if 1 or two pokes felt at the same time
68
What is extinction ?
impairs ability to percieve multiple stimuli at the same type simultaneously - touch both sides of the boy with paperclip at same time - patient states how many touches were felt
69
What can a compression of the nerve cause ?
absence of sensation
70
What is consciousness ?
awareness, arousal and cognition
71
Which people are at most risk for skin breakage like pressure ulcers ?
people with diminished/loss of sensation - like older adults
72
When is the expected age for the Palmar Grasp ?
birth to 3-4 months - can reemerge after a brain injury and sometimes it can cause the family of the patient to think they are doing it voluntarily and that means they'll be okay but instead it's a reflexive action
73
What does the frontal lobe do ?
- motor decision making (impulse control) - personality
74
What does the temporal lobe do ?
- hearing
75
What does the parietal lobe do ?
sensory - touch, shape, and taste
76
What does the cerebellum do ?
balance and coordination
77
What is Wernicke's area and in which lobe is it in ?
concerned with comprehension of language - in temporal lobe - damage to this area causes you to speech fluently but can't understand or use basic nouns
78
What is Broca's area and in which lobe is it in ?
concerned with speech and language production - frontal lobe
79
What assessment test can we perform to assess for peripheral nervous sensory function ?
light touch sensation
80
What is the function of the occipital lobe ?
vision
