Lower portion of the brain stem; regulates heart rate, blood pressure, breathing and reflexes.

Section of the brain that coordinates body movements, including balance.

The ____ is a tiny bone in middle ear that transmits sound from tympanic membrane to anvil.

Oculomotor nerve

The section of the brain located below the midbrain that plays a role in regulating breathing.

The irregularly shaped outer portion of the ear is called the ____.

Connecting the middle ear to the pharynx ____ equalizes pressure on either side of tympanic membrane

Vagus nerve

Sections of the brain located behind the parietal lobes; primarily used for vision and speech.
