what part of the brain contains the thalamus and hypothalamus?
diencephalon
what part of the brain connects the cerebrum and diencephalon with spinal cord?
brain stem
how many steps are included in the CSF process?
4 steps included
effects of the sympathetic systems
increase HR, increase BP, dilation of bronchial tubes, increase in basal metabolic rate, dilation of pupils
A patient is admitted after a stroke affecting the frontal lobe of the brain. Which function is most likely to be impaired?

C. Problem-solving and voluntary movement
what are the division of the brain
midbrain, pons, medulla oblongata
what does the medulla oblongata do?
it helps regulate respiration control of vitals
what does the CSF do?
it permits exchange of nutrients and wastes between blood and neurons
