What is the largest part of the brain?
cerebrum
Where is the primary motor cortex located?

midbrain, pons, and medullar oblongata
What does the midbrain do?
relay stimuli concerning muscle movement to other brain structures
What does the pons do?
relays impulses to brain centers and lower spinal nerves
What does the medulla oblongata contain and what does it do?
contains reflex centers for controlling involuntary movements functions such as breathing, sneezing, swallowing, coughing, vomiting, and vasoconstriction
