Review of cerebral structures and umn and lmn involvement
Question | Answer |
---|---|
Frontal Lobe: Precentral, Prefrontal, Premotor | Precentral - Primary motor cortex, Prefrontal - Controls emotions/judgement, Premotor - Related to the planning of movement |
Parietal Lobe: Postcentral | Postcentral - Primary sensory cortex |
Temporal Lobe: Primary Auditory, Associative Auditory, Wernicke's area | Primary Auditory- Receives/Processes auditory info, Associative Auditory - secondary auditory processor, Wernicke's area - language comprehension (receptive) |
Occipital Lobe: Primary Visual, Visual Association | Primary Visual - Receives/Processes Visual stimuli, Visual Association - secondary |
Upper motor neuron involvement | Spinal cord and superior structures increase deep tendon reflex, spasticity, clonus, primitive reflexes, autonomic disreflexia, flaccidity |
Lower motor neuron involvement | Anterior horn to muscle: flaccidity, decrease deep tendon reflexes, atrophy |
