sympathetic - 'fight and flight' system, involves during emergency, pupils dilated
parasympathetic - keeping body energy use low, involves during digestion, pupil constricted
differentiate pyramidal and extrapyramidal in descendng tract
track : pyramidal vs extrapyramidal
travel : voluntary muscle control vs do not travel pyramids of medulla
track involved : corticospinal vs rubrospinal
descending tracts are the pathways that carry motor commands from higher centers to lower motor neurons.
the extrapyramidal tract is responsible for coordinating involuntary movements such as posture, balance, and eye movement through its connections with basal ganglia and other subcortical structures.
the pyramidal tract is responsible for controlling voluntary movements of skeletal muscles through its connection with upper motor neurons in the cerebral cortex.
