Don't be NERVOUS
The two components of the central nervous system.
What are the brain and spinal cord?
Use of a computer to generate three-dimensional images. Especially effective in diagnosing disorders of the brain and spinal cord also used to visualize tumors, abscesses hemorrhage, and trauma. Produces an image of a single plane (a slice of the body). Does not require the use of contrast chemicals.
What is Computed Tomography (CT)?
Helps control balance, muscle coordination, movement memory
What is cerebellum?
Inflammation of the meninges.
May be caused by: Bacteria, Viruses, Fungi, or Parasites
What is MENINGITIS?
Muscle fasciculation (twitching)
Difficulty speaking and swallowing
Eventually, respiratory failure and total paralysis occur
What is ALS?
The "rest and digest" subdivision of the nervous system.
What is the parasympathetic nervous system?
A electrical recording of a muscle activity that aids in the diagnosis of neuromuscular disease.
What is electromyography (EMG)?
Controls basic life-support functions: breathing, circulation, swallowing
What is Medulla?
A degenerative condition resulting in the diminishment of mobility and a mask-like expression.
What is Parkinson's Disease?
Hallucinations/Delusions
Impaired judgement
Increased intensity of abnormal movement
Severe depression is common, and may lead to suicide
What is Huntington's Disease?
A fatty substance that speeds the signal traveling down the axon
What is myelin sheath?
Imaging procedure that records metabolic activity. Used to scan brain and nervous tissue. Identifies areas of abnormal activity that occur in schizophrenia, tumors, epilepsy, stroke, and Alzheimer Disease.
What is Positron Emission Tomography (PET)?
What are the 4 main lobes?
1. Frontal
2. Parietal
3. Temporal
4. Occipital
A neuromuscular disorder that results in improper communication between the CNS and other parts of your body.
What is MULTIPLE SCLEROSIS?
Headache, fever, stiff neck, photophobia, seizures, eventually death
What is Meningitis?
The three membranes covering the brain and spinal cord. OUTERMOST LAYER: Dura Mater MIDDLE LAYER: Arachnoid Mater INNERMOST LAYER: Pia Mater
What are the meninges?
Neurological test that uses an electronic monitoring device to measure and record electrical activity in the brain. It is a superficial exam in the sense that the electrodes are placed on the skull - they are not implanted in the brain.
What is electroencephalography (EEG)?
consist of two hemispheres which control emotion, hearing, vision and personality
What is Cerebrum?
A Heredity disorder of the Nervous System where symptoms develop slowly over time.
What is Huntington's Disease?
Initially: vision problems, weakness, clumsiness, tremor, mood swings
Eventually: ataxia or paraplegia, incontinence, blindness, loss of memory, difficulty concentrating and impaired judgement
What is MULTIPLE SCLEROSIS?
Nerves that arise from the brain itself (rather than the spinal cord). They pass through the openings of the skull. There are 12 pair. These nerves carry impulses from brain to muscles, skin, and organs of head and neck.
What are the Cranial Nerves?
a needle is inserted into the space between two lumbar bones (vertebrae) to remove a sample of cerebrospinal fluid.
What is Lumbar Puncture?
Where is executive functioning (control, plan, direct and initiate activities, motor functions) located?
What is the frontal lobe?
Occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts.
What is stroke?
Rigidity
Hand Tremor
Bradykinesia
Shuffling Gait
Stopped Posture
What is Parkinson's Disease?
