CSD 155 Lab 13: Neurology Flashcards
1
Q
cortical structures
A
- cerebrum
- cerebellum
2
Q
cerebrum
A
- frontal lobe
- parietal lobe
- occipital lobe
- temporal lobe
3
Q
frontal lobe
A
- most anterior lobe of brain, bound inferiorly by lateral sulcus posteriorly by central sulcus
- functions: initiating voluntary motor movements (includes Broca’s area), regulate personality, control executive functioning
4
Q
parietal lobe
A
- bound anteriorly by central sulcus, bound posteriorly by lateral sulcus
- functions: take in sensory information
5
Q
temporal lobe
A
- bound medially by lateral sulcus, projects back to parietal and occipital lobes posteriorly
- functions: take in and process auditory information, oral language comprehension (Wernicke’s area)
6
Q
occipital lobe
A
- most posterior lobe of brain
- function: take in and process visual information
7
Q
cerebellum
A
- visible structure located below the cerebrum
- function: coordinate motor movements with incoming sensory information. controls aspects of movement like posture and gait; communicates with the cerebrum, brain stem, and spinal cord
8
Q
subcortical structures
A
- insular lobe
- limbic lobe
- basal ganglia
- hippocampal formation
- thalamus
- subthalamus
- hypothalamus
9
Q
insular lobe
A
insular cortex/island of Reil
- sits deep to the cerebrum, consists of portions of the frontal, parietal, and temporal lobes
10
Q
limbic lobe
A
- located deep within cerebrum
- function: controls emotions, drives, motivation
- parts: cingulate gyrus, uncus, and parahippocampal gyrus
11
Q
basal ganglia
A
- group of nuclei deep within the cerebrum
- functions: maintain posture and balance, control underlying muscle tone, initiate movement, control speed and amplitude of movement
12
Q
hippocampal formation
A
- functions: mainly memory, can perform other functions via connections to other structures
13
Q
thalamus
A
- function: relays sensory information coming into the place it should go to be processed, takes in motor information from cerebellum to send to the primary motor strip (in cortex, frontal lobe)
14
Q
subthalamus
A
- function: helps to control movement of striated muscles
15
Q
hypothalamus
A
- helps to control wants and needs (connected to limbic system), digestive and metabolic systems
