Responsible for the motor response of eye movement | CNIV Trochlear |
Both motor and sensory that is responsible for face sense and chewing | CNV Trigeminal |
Also a motor response for eye movement | CNVI Abducens |
Both motor and sensory responsible for expression, taste, and salivary secretions | CNVII Facial |
Sensory response for hearing and balance | CNVIII Auditory |
Both motor and sensory responsible for taste, swallowing, and parotid gland secretions | CNIX Glossopharyngeal |
Both motor and sensory responsible for digestive enzymes, HR, speech muscles, GI motility, resp, swallowing, cough, and vomit | CNX VAGUS |
Motor response that controls head and shoulder movement | CNXI Spinal accessory |
Motor response that controls tongue movement | CNXII hypoglossal |
Brain stem leaves the occipital bone through the | foramen magnum |
the brain stem is responsible for | resp. and cardiac |
what controls body temperature | hypothalamus |
conducts and impulse | neurons |
protects the neurons and form myelin and blood brain barrier. | neuroglia |
largest portion of the brain located around the cerebellum and is coated in cerebral cortex. Divided by corpus collosum. | cerebrum |
what substance makes up most of CSF | glucose |
CSF is produced in these ventricles | Choroid plexus |
dura, arachnoid, and pia are called | meninges |
section of the brain responsible for personality | central sulcus |
section of the brain responsible for speech | parietal lobe |
section of the brain responsible for visual | occipital lobe |
section of the brain responsible for auditory | temporal lobe |
separates temporal and frontal lobes | lateral sulcus |
section of brain responsible for writing motor and coordination. | Frontal lobe |
classified as a nerve tract | corpus collasum |
end of one neuron to the beginning of another | synaptic gap |
protects brain from chemicals and large substances | blood brain barrier |
electrical conduction down the axon | saltatory conduction |
motor neurons are made of | dendrites and axons |
excite or inhibit neurons; chemicals released by synaptic nobs | neurotransmitters |
fatty substance covers axon | myelin |
when the left side of the brain controls the right side of the body and vice versa | contralateral |
space in the meninges that holds CSF | subarachnoid space |
end of spinal nerve | caudaequina |
ventral motor roots | dorsal sensory |
spinal never root innervates a specific area (map) | dermatones |
fight or flight; released during stressful situations, emotions, and severe illness | sympathetic nervous system |
Sympathetic Nervous system prompts adrenal medulla to produce what three catecholamines? | dopamine, Norepinephrine, and epinephrine |
Nervous system that slows HR, increases GI, and encourages eliminating body waste | Parasympathetic (PNS) |
PNS produces this hormone that increases skeletal muscle contraction and causes cardiac muscle relaxation. | Acetylcholine |
posture leaning away from pain | antalgia posture |
for a head, neck, and spine injury, what places would you look for cerebral spinal fluid leaks? | Mouth, nose, eyes, and ears |
posturing with arms flexed, fist clenched, and legs extended | decorticate |
posturing with stiff and rigid extremities | decerebrate |
no motor response (posture) | flaccidity |
pt can be aroused only to fall asleep again | somnolent |
what score on the glasgow coma scale indicates a comatose state? | 7 or below |
size of normal pupil dilation | 2-3 mm |
diagnostic test used if pt has metal in the body | Computed tomography (CT) |
radio frequency used to show tissue, veins, and arteries | Magnetic Resonance Imaging (MRI) |
shows brain's cerebral blood flow and status of receptors used to diagnose Alzheimer's and Parkinson's | Single-Proton emission computed tomography (SPECT) |
shows metabolic activity of a body structure | Positron emission tomography (PET) |
what position do you place the patient in for a lumbar puncture | side-lying (knee to chest) or tripod |
what is the location of a lumbar puncture | L3 or L4 |
Lumbar punctures show the presence of pathogenic microorganisms by removing fluid from where? | subarachnoid space |
contrast study that detects distortion of cerebral arteries and veins; shows the blood flow to brain; diagnose aneurysms | cerebral angiography |
shows electrical impulses generated in the brain | Electroencephalogram (EEG) |
shows nerve injury or compression; diagnoses carpal tunnel and peripheral neuropathy | Nerve conduction study |
ultrasound of the brain | Echoencephalography |
A way to cure a HA after a spinal tap; often given with sumatriptin; 20-30 mL of venous blood put into the spine | blood patch |
electrical potential to muscles and nerve supply to musles | Electromyography (EMG) |
what should you avoid prior to an EMG | anticoagulants and blood thinners |
part of the vertebrae that bears weight | vertebral body |
dilation/constriction of cerebral blood vessel in response to changes in BP, O2, and pH maintains constant and consisten tissue perfusion | ICP |
Leads to altered VS | pressure on brainstem via foramen magnum |
when is a HA more severe with ICP | AM |
pulse rate increases then decrease, systolic BP increases (widened pulse pressure), resp. rate irregular (cheyne-stokes) | Cushings Triad |
what type of solution should you avoid with ICP because it could increase it's symptoms | hypotonic |
the HOB should be in what position to decrease HA with ICP | midline at 30 degrees |
use this osmotic diuretic to decrease fluid in the body (ICP) | mannitol |
