Neurological Flashcards
Anatomical components of nervous system?
Brain, spinal cord (central) , nerves (peripheral)
Autonomic Nervous System
The part of the Efferent Nervous System that controls involuntary functions split into sympathetic and parasympathetic
Somatic Nervous System
The part of the Efferent Nervous System that controls voluntary movements
Structure of the brain
Ventricles - Cavities in the brain filled with cerebrospinal fluid.
Brainstem - The area that connects the sinal cord to the brain
Cerebellum - Posterior to brainstem ‘string part at back of brain
Hypothalamus - Anterior to the brain stem connected to midbrain
Thalamus - The area above the brain stem
Cerebrum - Outer part of the brain seperated into lobes
Structure of the brainstem
Medulla - The lowest part of the brain stem where the spinal cord connects
Pons - Middle part of the brain stem
Midbrain - Highest part of the brain stem where the brain connects
What are the meninges
Protective layers surrounding the brain and spinal cord
Where is cerebrospinal fluid
In ventricles
Surrounding brain
Central spinal canal
Surrounding spinal cord
GCS breakdown
Eyes/4 (Follows, to speech, to pain, closed)
Speech/5 (Orientated, confused, Innapropriate, incomprehensible, none)
Motor/6 (Follows commands, localises to pain, withdraws, flexes, extends, none)
BEFAST breakdown
Balance
Eyes
Face
Arms
Speech
Time
Sympathetic Nervous System
Part of the Autonomic Nervous System responsible for fight or flight
Parasympathetic Nervous System
Partof the Autonomic Nervous System responsible for rest and digest
Afferent Nervous System
Part of the PNS responsible for sensory
Efferent Nervous System
Part of the PNS responsible for motor
Global overview
Gait
Facial drooping
Muscle wasting
Tremor
Posture
Walking aide
Meningitis tests
Kernig’s sign
Brudzinski sign
Kernig’s sign
Lie flat, flex knee 90 degrees and slowly straighten. Pain in neck or head is positive indicator
Brudzinski’s sign
Lie flat and manually maneuvre head to chest. Flexion at the hips or knees is a positive indicator
What is meningitis
Inflammation of the meninges indicating infection of the subarachnoid space (where cerebrospinal fluid is)
Dysarthria
Slurring
Dysphonia
Hoarseness
Dysphasia
Innappropriate words
Cerebral cortex lobes
Frontal - front
Parietal - Upper middle
Temporal - Lower middle
Occipital - Rear
Cranial Nerve 1
Olfactory
Sensory
Begins at cerebrum
Responsible for smell
