Front 28

Parts of Brainstem

Back 28

Midbrain, Pons, Medulla Oblongata

Front 29

Parts of Diencephalon

Back 29

Thalamus, Hypothalamus,

Front 30

Parts of Midbrain

Back 30

Superior Colliculus, Inferior Colliculus

Front 31

Medulla Oblongata

Back 31

Contains nuclei w/ functions: regultion of heart rate and blood vessel diameter, breathing, swallowing, vomiting, coughing, sneezing, balance, and coordination.

Front 32

Pons

Back 32

Functions: Breathing, swallowing and balance; chewing and salivation

Front 33

Midbrain

Back 33

major relay centers for the auditory nerve pathways in the CNS

Front 34

Diencephalon

Back 34

Main parts are epithalamus and hypothalamus

Front 35

Thalamus

Back 35

Sends axons to the cerebral cortex. Influences mood and registers and unlocalized, uncomfortable perception of pain.

Front 36

Epithalamus

Back 36

Few small nuclei that are involved in the emotional and visceral response to odors, and the pineal body.

Front 37

Hypothalamus

Back 37

Controls body temperature, hunger, and thirst. Sexual pleasure.

Front 38

Only sensory nerves
