Frontal lobe

Front 6

plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved with visuospatial processing

Back 6

Parietal lobe

controls sense of sight; lesions can produce hallucinations

Back 7

Occipital lobe

Front 8

Controls senses of smell and sound, as well as processing of complex stimuli like faces and scenes.

Back 8

Temporal lobe

Front 9

a portion of cortex in between and covered by the temporal and parietal lobes. Many sources consider it a separate lobe, and some group it with limbic structures deep in the brain into a limbic lobe

Back 9

Insula

Back 23

pia mater

Front 24

mambranous partition of duramater that extends as flat partitions deep into the cranial cavity.

Back 24

2.a spinal chord
2 b arachnoid space
3. veinous blood.

Front 32

Strictly regulates what substances can enter the interstitial fluid of the brain. prevents exposure to drugs, waste products, and variation of normal substances that can harm the brain

Back 32

blood brain barrier

Front 33

name the 3 area that have less or no blood brain barrier

Back 33
