Answer
|
Precentral Gyrus
|
Part of the frontal lobe. Primary MOTOR cortex for voluntary muscle
activation.
|
Prefrontal Cortex
|
Controls emotions and judgment.
|
Broca's Area
|
Controls motor aspects of speech
|
Postcentral Gyrus
|
Part of the parietal lobe. Primary SENSORY cortex for the integration
of sensations.
|
Primary (and Associative) Auditory Cortex
|
Part of the temporal lobe. Receives & processes auditory stimuli.
|
Wernicke's Area
|
For language comprehension.
|
Primary Visual Cortex
|
Part of occipital lobe. Receives & processes visual stimuli
|
Insula
|
Within the lateral sulcus, for visceral functions.
|
Limbic System
|
Consists of limbic lobe, hippocampus, hypothalamus, amygdaloid, and
anterior nucleus of thalamus. For feeding, aggression, emotions, endocrine
aspects of sexual response.
|
Basal Ganglia
|
Forms associated motor system. Occulomotor, skeletomotor, and limbic
circuits.
|
Occulomotor Circuit (cuadate loop)
|
Functions with saccadic eye movements.
|
Skeletomotor Circuit (putamen loop)
|
Controls amplitude & velocity of movement, reinforces a selected
pattern while suppressing conflicting patterns; preparation/anticipation for
movement.
|
Limbic Circuit
|
Organizes behaviours, executive functions, problem solving, motivation
and procedural learning.
|
Thalamus (Diencephalon)
|
Sensory nuclei to relay information to cerebral cortex. Motor nuclei
relays motor information from cerebellum & globus pallidus to precentral
motor cortex. Other nuclei also assist in integration of visceral &
somatic functions.
|
Subthalamus
|
Control of several functional pathways for sensory, motor, and
reticular formation.
|
Hypothalamus
|
Controls functions of ANS & body homeostasis (temp, eating, water
balance, pituitary).
|
Dorsal Column/Medial Lemniscal
|
Afferents for proprioception, vibration, tactile discrimination.
Fasciculus cuneatus (UE) & Fasciculus gracilis (LE). Tract crosses in the
medulla going to thalamus.
|
Spinothalamic Tracts
|
Afferents for pain & temp, and gross touch. Tracts ascend 1or2
segments in Lissauer's tract then cross.
|
Spinocerebellar Tracts
|
Convey proprioception info from muscle spindles, GTO's, touch, and
pressure receptors to cerebellum for control of voluntary movement. Dorsal
tract ascends ipsilaterally to ICP. Ventral tract ascends to
contra/ipsilateral SCP's.
|
Spinoreticular Tracts
|
Convey deep & chronic pain to reticular formation of the brainstem
via diffuse polysynaptic pathways.
|
Plexuses
|
Cervical (C1-C4), Brachial (C5-T1), Lumbar (T12-L4), Sacral (L4-S3)
|
Levels of Consciousness (arousal)
|
Alertness, Lethargy, Obtundation, Stupor, Coma
|
Glasgow Coma Scale
|
3 elements (EMV): eye movement, motor response, verbal response. Mild
brain injury (13-15), Moderate (9-12), Severe (3-8).
|
Mini-Mental Status Exam
|
For cognitive dysfunction. Max score of 30. Mild impairment (21-24),
Moderate (16-20), Severe (15 and below).
|
Rancho Los Amigos Levels of Cognitive Function (LOCF)
|
Assesses cognitive recovery from TBI. 8 levels: no response (I),
decreased response (II, III), confused (IV, V, VI), appropriate (VII, VIII).
|
Weber's Test
|
Strike tuning fork & place handle on middle of forehead. Examine
for hearing perceived in middle of head or one ear only.
|
Rinne Test
|
For air vs. bone conduction. Strike tuning fork & place on mastoid
process, then place near external ear canal to check hearing acuity.
|
Cheyne-Stokes Respiration
|
Period of apnea lasting 10-60 seconds followed by gradually increasing
depth & frequency of respiration.
|
Tests for Meningeal Irritation
|
Neck mobility, Kernig's sign, Brudzinski's sign.
|
Modified Ashworth Scale
|
6 grades of spasticity. No increase in tone(0). Resistance @ end ROM
(1). Resistance through < half ROM (1+). Resistance through most ROM, part
still easily moved (2). PROM difficult (3). Rigidity (4).
|
Common Reflexes

Jaw (CN V), biceps (C5-C6), triceps (C7-C8), brachioradialis (C5-C6),
hamstrings (L5-S3), quads (L2-L4), achilles (S1-S2), plantar (S1-S2).
|
Strength Duration Curve
|
Strength (intensity) on Y axis, duration (time) on X axis.
|
Rheobase
|
Intensity of current to produce a visible twitch.
|
Chronaxie
|
Duration of a stimulus twice rheobase that will elicit a muscle
twitch. Chronaxie of an intact nerve & innervated muscle is much lower
than that of a denervated muscle.
|
Middle Cerebral Artery (MCA) Syndrome
|
MCA supplies lateral cortex, BG, and internal capsule. Occlusions
produce contralateral sensory loss and hemiparesis with UE more involved than
LE. Maybe also Broca's aphasia.
|
Anterior Cerebral Artery (ACA) Syndrome
|
The ACA supplies the medial cortex. Occlusions produce contralateral
sensory loss and hemiparesis with the LE more involved than UE.
|
Posterior Cerebral Artery (PCA) Syndrome
|
Occlusions may cause contralateral homonymous hemianopsia,
contralateral sensory loss, involuntary movements and more.
|
Fugl-Meyer Assessment of Physical Performance
|
Scoring of movements 0(can't perform),1,2(fully performed). Includes
subtests of UE, LE, balance, sensation, ROM, and pain.
|
Motor Assessment Scale
|
Measures functional capabilities using eight categories and provides
criteria for scoring performance.

not UNDERESTIMATE ability to learn
|
Guidelines to promote learning in patients with RIGHT hemisphere
lesions

Wallerian degeneration
|
Degeneration of the axon and myelin sheath distal to the site of
injury
|
Neurapraxia (Class 1)
|
Injury to a nerve that causes transient loss of function (conduction
block ischemia, compression injury, etc.). Nerve dysfunction may be rapidly
reversed or last a few weeks.
|
Axonotmesis (Class 2)
|
Injury to the nerve interrupting the axon, causing loss of function
and Wallerian degeneration. No disruption to the endoneurium, so regeneration
is possibe. (crush injury).
|
Neurotomesis (Class 3)
|
Cutting of the nerve with complete severance of all structures &
complete loss of function. Regeneration unlikely without surgery (terminal
ends can't meet).
|
Bulbar Palsy
|
Weakness or paralysis of the muscles innervated by motor nuclei of
lower brainstem, affecting the muscles of the face, tongue, larynx and
pharynx.
|
Guillain-Barre syndrome
