Maintains internal environment
The two FUNCTIONAL divisions of the nervous system?
Somatic
Autonomic
Function of somatic nervous system?
Controls motor and sensory function for body wall
Function of autonomic nervous system?
Controls visceral function
Functional unit of nervous system?
Neurone

3 diagnostic methods for nerve damage?
Patient history
Neurological examination
Specific methods
Components of patient history important for diagnosis? (5)
Symptoms Duration of symptoms Other illnesses Social situation etc Observation of patient (abnormalities)
Components of neurological examination for diagnosis? (6)
Level of consciousness Speech Mental state and cognitive function Sensory function Motor function Cranial nerve function
Specific methods of nerve damage assessment? (5)
EEG -electroencephalography EMG - electromyography NCS - nerve conduction studies CT - computerised tomography MRI - magnetic resonance imaging
