FOR GUARANTEED PASS
Functions of the Limbic System - CORRECT ANSWER - Drives basic instincts, "animal-like"
aspects of a human - if damaged can cause emotional responses that can become uncontrollable
Amygdala - CORRECT ANSWER - Part of the limbic system - responsible for emotional
memories, closely tied to sense of smell
Hippocampus - CORRECT ANSWER - Part of the limbic system - responsible for the
organization of memories
Basal Ganglia - CORRECT ANSWER - Part of the limbic system - relays information from
cerebral cortex to brain stem and cerebellum for movement, the checking system that comes to
attention when things are not working as they should be i.e. restoring equilibrium
Cerebellum - CORRECT ANSWER - Governs a person's movements by controlling rate,
direction, force and steadiness of movements
Cerebral Cortex - CORRECT ANSWER - Made up of right and left hemisphere and corpus
collosum
Functions of the Right Hemisphere - CORRECT ANSWER - Holistic, visual spatial and ,
intuitive in nature
Associated with art, shapes, music, and faces
Functions of Left Hemipshere - CORRECT ANSWER - Linear, verbal-analytic, logical in nature
Associated with speaking, reading, and calculating
,Corpus Collosum - CORRECT ANSWER - Pencil-thick band that exhanges info between L and
R hemispheres
Afferent Signals - CORRECT ANSWER - Signals sent along the spinal cord through foremen
magnum towards the central nervous system
Efferent Signals - CORRECT ANSWER - Signals sent from the central nervous system to the
rest of the body through the foramen magnum via the spinal cord
Cervical Vertebrae - CORRECT ANSWER - Made up of 7 vertebrae, primary function to support
and move the skull
Thoracic Vertebrae - CORRECT ANSWER - Made up of 12 vertebrae, primary function is
stability
Lumbar Vertebrae - CORRECT ANSWER - Made up of 5 vertebrae, primary function is weight
bearing
Sacral Vertebrae - CORRECT ANSWER - Made up of 5 vertebrae, located at the base of the
spine meeting the pelvis
CT Scan - CORRECT ANSWER - X-ray used in conjunction with a computer, only capable of
showing what the naked eye can see
MRI - CORRECT ANSWER - Uses magnetic field in conjunction with a computer, a more
detailed scan ideal for seeing soft tissue damage, can detect changes in blood flow and track
cellular activity
Blood Brain Barrier - CORRECT ANSWER - A filter within the red blood cells which allows
blood to enter the brain but blocks harmful substances from entering
,Neuroplasticity - CORRECT ANSWER - The ability of the nervous system to change, grow, or
compensate for an injury
The brain can change and re-map! Based on the Hebbian Principle which states that every
rehearsal of a skill strengthens memory trace in the brain
Hippocampus may contain stem cells which can generate new brain cells if optimized by
therapy!
Synaptogenesis - CORRECT ANSWER - A part of nueroplasticity - the formation of synapses
between nuerons
The more synapses there are the more efficiently nuerons can communicate!
Nueroprotection - CORRECT ANSWER - Preventing secondary damage post injury
Apoptosis - CORRECT ANSWER - Process in which a brain cell self destructs if it is not
working as it should be
Experience Dependent Learning - CORRECT ANSWER - Neural connections that are
established which depend entirely on and are due to an environmental experience
Autonomic Storming - CORRECT ANSWER - Also called dysautonomia, autonomic
hyperreflexia, sympathetic storming
A disorder of the autonomic nervous system that involves failure of the - CORRECT ANSWER -
sympathetic/parasympathetic components of the ANS.
Characterized by resting tachycardia, labored breathing, gastroparesis, sweating irregularities,
hypotension, constipation, and erectile disfunction
15-33% of TBIs sustainees experience AS
Deep Vein Thrombosis (DVT) - CORRECT ANSWER – Blood clots
, Symptoms include shortness of breath, pain/discomfort that worsens with coughing or breathing,
light headedness, dizziness, feeling faint, coughing up blood, rapid pulse
Pulmonary Embolism (PE) - CORRECT ANSWER - Occurs when a blood clot travels to the
lungs- same symptoms for DVT
Disinhibited Nuerogenic Bladder - CORRECT ANSWER - Neurological impairment in CNS or
PNS causing decreased bladder capacity, increased urgency, increased frequency and
incontinence with intact bladder sensation
Treatment for Bowel and Bladder Incontinence - CORRECT ANSWER - Best when initiate
early on - treatment includes exterior cathing and suppository schedules, toileting schedules, and
close monitoring of intake
UTI's extremely common due to cathing - risk of UTI is increased with use of in-dwelling
catheters, especially if cognitive impairment is present
Aspiration - CORRECT ANSWER - Caused by dysphagia - when liquid enters into the lungs
Commonly leads to aspiration pneumonia
Specialized diets are often prescribed if there is a risk of dysphagia - may include thickened
liquids and diets with altered consistency
Seizures and TBI - CORRECT ANSWER - Caused by an imbalance of nuerotransmitters or an
abnormal and disorderly discharge of electrical activity in the cells of the brain
TBI sustainees 22x more likely to die from a seizure than general population
Immediate post TBI convulsions are most common but not believed to be a predictor of
prolonged seizure disorder
Seizures occurring 1 wk post TBI are strong predictor of future patterns
Status Epilepticus - CORRECT ANSWER - A seizure lasting longer than 5 minutes or seizures
that occur close together, when one seizure occurs before fully recovering from previous seizure
