Nervous SystemStructure vs Function

Hindbrain

•Upper spinal cord

•Brain stem

•Cerebellum

Hindbrain

• Controls respiration and heart rate

• Cerebellum (1)– Coordinates movement and is involved in

learned rote movements– Balance and posture

•

Midbrain

• Brainstem – Heart rate, breathing, eating, and sleeping

Forebrain- Cerebrum (2)

• Divided into lobes = various functions– Frontal (3)

• Decision making and problem solving• short-term storage sites • Motor Area (4)

–helps control voluntary movement • Broca’s Area (5)

–allows thoughts to be transformed into words

Forebrain…cont.

• Parietal Lobe (6)– Reading and arithmetic

• Where letters form words, words form thoughts

– Processes sensory info• When you enjoy a good meal—the taste, aroma,

and texture of the food • forward parts of these lobes, just behind the motor

areas, are the primary sensory areas (7) – temperature, taste, touch, and movement from the rest of

the body

Forebrain…cont.

• Occipital Lobe (8)– process images from the eyes and link that

information with images stored in memory. Damage to the occipital lobes can cause blindness

Forebrain…cont.

• Temporal Lobe (9)– Top

• Receives info from ears (symphony vs rock music)

– Underside• Forming and retrieving memories

– Other• Integrate memories and sensations of taste, sound

(language), sight, and touch.

Cerebral Cortex

• Coating the surface of the cerebrum and the cerebellum is a vital layer of tissue the thickness of a stack of two or three dimes– Most information processing – "gray matter" in the brain- nerves in this area

lack myelin insulation

Inner Brain

• Determine our emotional state, modify our perceptions and responses, and allow us to initiate movements that you make without thinking– Hypothalamus (10)

• Wakes you up in the morning, gets the adrenaline flowing during a test or job interview, and emotional center

– Thalamus (11)• major clearinghouse for information going to and from the

spinal cord and the cerebrum – Hippocampus (12)

• Memory index for long-term storage
