Q
gyri
A
raised ridges of cerebrum
6
Q
sulci
A
shallow grooves that separate gyri
7
Q
transverse fissure
A
divides cerebrum from cerebellum
8
Q
median longitudinal fissure
A
divides left + right cerebral hemispheres
9
Q
cerebral cortex
A
- outer portion of cerebrum
- highly convoluted, gray colored
- contains primary + association areas
10
Q
frontal lobe functions (3)
A
- higher level executive functions
- motor functions
- voluntary muscle action
11
Q
parietal lobe function
A
- receives sensory info from receptors in mouth/skin
12
Q
occipital lobe function
A
- interprets visual input
13
Q
temporal lobe functions (2)
A
- contains sensory area for hearing
- contains sensory area for smell
14
Q
primary areas of cerebral cortex
A
receive and send info for one type of sensory or motor information
15
Q
association areas
A
- integrate more than one type of sensory info for personal action
- all 4 lobes have them
