Answer:
Answer is D.
Medulla Oblongata.
Explanation:
This is the posterior end of the brain that continues into the spinal chord. This part of the brain has an outer region of white matter and an inner region of grey matter. It controls involuntary movements in the body especially those concerned with respiration, heartbeat and digestion.
During emotional stress, fear, or anger, impulses travel down the cerebrum to the medulla causing increased rate of sweating, heartbeat and breathing. These processes makes it the peacemaker of inhalation.
