2

PARTS OF THE BRAINSTEM

pons: connects the medulla oblongata, the cerebellum, and cerebrum

midbrain: contains auditory (hearing), visual (sight), and muscle control centers.

medulla oblongata: lowest and most posterior(at the back of the brain)

The hindbrain includes the pons and the

medulla.3

THE BRAINSTEM

THE PONS (THE BRIDGE)

Connects the medulla oblongata, cerebellum, and cerebrumAssociates with sensory nerves: taste, hearing, and balance.

Controls muscles of the face.

5

THE MEDULLA OBLONGATA

controls alertness heart action respiration (breathing) blood pressure

connects the CEREBRUM with the SPINAL CORD the RIGHT side of the brain controls the LEFT side of the body. the LEFT side of the brain controls the RIGHT side of the body.

THE MIDBRAIN

7

THE CEREBELLUM

coordinates muscle activity.has three parts:the vermisthe right cerebellar hemispherethe left cerebellar hemisphere

8

THE DIENCEPHALON P

is located between the midbrain and the cerebrumhas three parts:the thalamus: receives sensory information and sends it to the cerebral cortex.the epithalamus: contains the pineal body and olfactory centers.the hypothalamus: connects the endocrine and nervous systems.

THE CEREBRUM

is divided into two cerebral hemisphereshas an outer surface,

or CORTEX,

made of “gray matter”

www.laskerfoundation.org 11

THE CEREBRAL CORTEX

is divided into parts called lobes:1. the frontal lobe2. the parietal lobe3. the temporal lobe4. the occipital lobe

12www.colorado.edu

THE FRONTAL LOBE

is the center for voluntary movementis called the “motor area” (movement)includes the prefrontal area,

for intelligence, creativity, memory, and ideas.

13

THE PARIETAL LOBE

Collects, recognizes, and organizes sensations:feelings of

paintemperaturetouchpositionmovement

14

THE TEMPORAL LOBE

processes auditory (hearing) information stores auditory (hearing) and visual (seeing)

memories includes Broca’s speech area

15

THE OCCIPITAL LOBE

is at the back of the cerebral hemisphereinvolves
