Which division of the brain holds the midbrain, pons, and medulla oblongata?
The brain stem
What is the function of the midbrain?
Relay center for eye and ear impulses
What is the function of the pons?
ConnecTion between the cerebrum and medulla, as well as various reflex actions
What is the function of the medulla oblongata?
