# BAS 03 Nervous System
Question | Answer |
---|---|
axon | Part of the nerve that sends the signal |
dendrite | part of the nerve that receives the signal |
CNS | Brain & Spinal cord make up the central nervous system |
PNS | Peripheral nerves outside the spine make up the peripheral nervous system |
ANS | Autonomic nervous system. Basic life functions are automatic. Nerves of the base brain and cranial nerves are included |
synapse | gap between nerves. The area where one nerve sends message to the next nerve. |
Cell body | Nerve cell area that contains the nucleus |
myelin | protective covering around the axon |
meninges | protective tissue surrounding the brain and spinal cord. |
myo- | muscle |
-pathy | disease |
neur/o | nerve |
neuropathy | nerve disease |
-algia | pain |
neuralgia | nerve pain |
encephal/o | brain |
encephalitis | brain inflammation |
myelo | spine |
myelography | scanned image of the spine |
-plegia | paralysis |
hemiplegia | paralysis on one half of the body. Arm,leg,and trunk |
paraplegia | paralysis of the lower body |
The patient presents a lack of sensation in the foot and ankle. Some of the times the patient feels pain in the toes and foot. There is no lower extermity stenosis. Dx is diabetic neuropathy. What is the code? | |
A patient wakes to find blurry vision in the left eye. Upon slit lamp exam and retinal exam the doctor diagnosis is vitreous hemorrhage. What is the code for each procedure and the code for the condition. | |
CC: patient complains of a "star halo" around lights. He first noticed the problem 3 nights ago when driving. Dx: doctor used densitometer to view the internal structures of the eye. Dx: cataract due to diabetes. What is the code. | |
A patient suffers a spinal injury and is left paraplegic. What is the code for this disease. | |
afferent | nerves that take sensory signals to the CNS |
efferent | nerves that send signals from CNS to muscles or glands |
cerebellum | controls balance, muscle tone, posture |
medulla oblongata | controls heart, lung |
cerebrum | large "thinking part" of the brain. |
thallamus | relay center for the sensations |
ventricles | cavitites of the brain. Filled with spinal fluid. |
CSF | cerebrospinal fluid. |
olfactory nerve | controls sense of smell |
oculomotor | controls eye movements |
optic nerve | controls vision` |
somatic nervous system | involved with sensing and voluntary muscle movements. |
autonomic nervous system | The part you don't think about. Signals go to internal organs and glands |
sympathetic nervous system | part of the ANS that gets you ready for stress. |
parasympathetic nervous system | part of athe ANS that gets you ready for relaxing. |
MRI | magnetic resonance imaging |
PET | Positron emission tomography |
CAT | Computerized axial tomography |
myelogram | xray of the spinal cord |
encephalography | xray of the ventricles of the brain |
concussion | injury to the brain |
contusion | brusing |
subdural hematoma | bleeding beneath the dura mater. |
alzheimers | dementia |
amyotrophic lateral sclerosis | degeneration of motor neurons |
motor | (movement) refers to nerve signals to muscles. |
