Hind-brain

"automatic survival functions"

contains brain-stem.

Brainstem

Directs essential survival functions. Ex: breathing, sleeping, alertness, coordination, and balance.

Medulla

Brain stems base. Controls heartbeat and breathing ;automatic functions.

Pons

Above medulla. Helps coordinate movements and control sleep, "limb body/paralysis."

Thalamus

A top of brain stem(medulla+pons." brains sensory control center. Directs messages to sensory receiving areas(except smell), transmits replies to cerebellum and medulla. "switch board operator"

Recticular Formation

Nerve network that travels through the brain-stem into the thalamus. Filters information, plays a role in alertness.

Cerebellum

Rear of the brain-stem. processing sensor input, coordinating movement output and balance, and enabling procedural learning.

if injured: difficulty in walking and keeping balance.
