Central sulcus

Answer 12

separates teh frontal lobe from teh parietal lobe
is very vertical in comparison to other sulci

Question 13

lateral sulcus

Answer 13

also called the sylvian fissure
separates frontal lobe from temporal lobe

separates parietal lobe on the inferior side

Question 15

calcarine sulcus

Answer 15

also on the inferior side of parietal lobe

Question 16

Limbic lobe

Answer 16

surrounds the diencephalon
between the telencephalon and diencephalon

Question 17

Precentral gyrus

Answer 17

anterior to central sulcus
contains the motor cortex

Question 18

Answer 18

partially on precentral gyrus
also on superior and medial frontal gyri
planning and initiation of movement

Question 19

Motor speech area

Answer 19

broca’s area/expressive area
opercular and triangular regions of inferior frontal gyrus

Question 20

Prefrontal cortex

Answer 20

all non-motor areas of frontal lobe
controls executive functions
personality, insight, and foresight

Question 21

Parietal lobe functions

Answer 21

somatosensory regions

Question 22

Answer 22

contains auditory processing areas
sensory speech area (wernike’s area)
visual processing
learning and memory (medial regions)

Question 23

Occipital lobe

Answer 23

is the main vision processing center

Question 24

Limbic lobe structures

Answer 24

cingulate gyrus
parahippocampal gyrus

Question 25

Limbic lobe function

Answer 25

emotional response drive related behavior memory

Question 26

diencephalon structures

Answer 26

Thalamus hypothalamus epithalamus subthalamus

Question 27

Thalamus

Answer 27

ovoid nucleus mass conveys info to the cerebral cortex from subcerebral sites only olfactory senses avoid thalamus fused at the interthalamic adhesion

Question 28

Hypothalamus

Answer 28

hypothalamic sulcus separates it from the thalamus- floor of the third ventricle infundibular stalk forms the inferior surfacealong with the mammilary bodies controls the autonomic nervous system

Question 29

Cerebellum regions

Answer 29

vermis two hemispheres

Question 30

amygdala

Answer 30

beneath the uncus of temporal lobe major component of limbic system

Question 31

Crossing over

Answer 31

somatosensory nerves cross in the spinal cord touch/motor cross in the medulla (pyramidal decussation) cerebellum receives information i[silaterally
