Brain Stem

• Stem-like portion of the brain that controls
  vegetative functions ( i.e. respiration's, heart
  rate), and connects the brain to the spinal cord.
• Divided into the midbrain, pons, Medulla
  Oblangata, and the Reticular Activity System.

12
Midbrain

• Involved in hearing and visual reflexes.

13
Pons

• Relays information from the cerebrum to the
  cerebellum.
• Houses the sleep center and the respiratory
  center, which along with the medulla controls
  breathing.

14
Medulla Oblangata

• Located between the pons and spinal cord.
• Contains the centers that control heart rate,
  respiration's, and constriction of vessel walls.

15
Reticular Activity System

• Responsible for consciousness.
• Keeps us alert and out of trouble.
• Involved in sleep-wake cycle.

12 Cranial Nerves

• I. Olfactory - Sense of smell.
• II. Optic - Vision.
• III. Oculomotor - Eye movements.
• IV. Trochlear - Eye movements.
• V. Trigeminal - Sensations of face, scalp and
  teeth, chewing movements.
• VI. Abducens - Turning eyes outwards.

18
12 Cranial Nerves

• VII. Facial - Sense of taste, facial expressions.
• VIII. Acoustic - Hearing, sense of balance.
• IX. Glossopharyngeal - Sensation of throat, taste
  swallowing movements, secretion of saliva.

19
12 Cranial Nerves

• X. Vagus - Sensations of throat and larynx and of
  thoracic and abdominal organs, swallowing, voice
  production, slowing of heartbeat, acceleration of
  peristalis (muscle contractions).
• XI. Spinal Accessory - Shoulder movements,
  turning of the head.
• XII. Hypoglossal - Tongue movements.

12 Cranial Nerves

• Cranial nerves do not cross. Therefore, a right
  cranial nerve insult will result in right sided
  deficit.
