Front 7

longitudinal fissure

Back 7

midline saggital suture, separates brain into hemispheres

Front 8

5 lobes of cerebral hemishpere

Back 8

frontal, parietal, occipital, temporal, insula
*limbic system sometimes given own lobe (limbic lobe)

Front 9

lateral fissure

Back 9

also called Sylvian fissure, separates parietal and temporal lobes

Front 10

central sulcus

Back 10

also called Rolandic sulcus, separates frontal and parietal lobes
*to find it look for 2 parallel gyri, not always obvious

Front 11

parieto-occipital sulcus

Back 11

on medial surface of hemisected brain, separates occipital lobe from the rest of the brain

Front 12

insula

Back 12

buried in lateral fissure, find by removing other lobes

Front 13

pre-central gyrus

Back 13

somato-motor cortex, controls volitional movements of contralateral side of the body

Front 14

frontal gyri

Back 14

superior, middle, and inferior

inferior separated into opercular, triangular, and orbital

Front 15

Broca's Area

Back 15

on dominant hemisphere, opercular and triangular parts, produce speech and use language

Front 16

frontal lobe functions

Back 16

voluntary eye movements, emotions, intellectual functions

damage to this part can have profound effects on personality

Front 17

orbital gyri function

Back 17

intellectual and emotional expression
