CNS Flashcards
What are the five lobes of the cerebral hemispheres?
frontal parietal occipital temporal insula
which four of the fives lobes correspond with the skull?
frontal, parietal, occipital, and temporal
what is the function of the frontal lobe?
Personality (alhimers disease) Analysis Executive (ability to know what your concentrating on. Ie. ADHD) Primary Motor Cortex (voluntary motor) Frontal Eye Fields Speech (Broca’s)
what is the function of occipital lobe?
sight, seeing
Primary Somatosensory (refers to touch) Cortex
parietal
Personality and Analysis are to what lobe?
frontal
what does dorsal visual system mean? what lobe is it significant to?
Dorsal Visual Stream (sends info. As to Where and How something is)
parietal
Spatial analysis (Orientation) Navigation
parietal lobe
Self-image (neglect)
Written to spoken word (have to see it comprehend then command to speak it)
what lobe?
Parietal Lobe
self image….what lobe?
parietal lobe.
primary somatoesory cortex is next to where?
motor cortex.
New memories: Hippocampus, Amygdala
Memory selection in temporal lobe (anterial grade amnesia= no new memory)
TEMPORAL LOBBE
Auditory cortex
TEMPORAL LOBE
SPIRITUALITY
TEMPORAL
Wernicke’s is what? associated with what lobe?
LANGUANGE COMPREHENSION.
TEMPORAL LOBE.
ventral visual system is what? what lobe?
what you are looking at.
TEMPORAL LOBE
SEIZURES…..WHAT LOBE?
TEMPORAL LOBE
VISUAL CORTEX (PRIMARY, SECOMDARY, AND TERTIARY) OPTICAL SEIZURES ARE ASSOCIATED WITH WHAT LOBE?
OCCIPITAL
Insula lobe is responsible for what? Located where?
Consciousness
Homeostasis (Autonomic)
Self-awareness
Under Frontal Lobe.
Difficulty recalling recent events Old memories intact Hippocampal damage Amygdala damage Korsakoff’s Syndrome what type of amnesia?
Anterograde Amenisia
Loss over older memories
Associated with traumatic injury
Usually memories near time of injury
Global amnesia Loss of identity Stroke, seizure Transient what type of amnesia?
retrograde amenesia
transverse fissure separates cerebellum from rest of brain. true or false.
true
cerebellum has to be separated from central hemisphere. true or false.
true
separates the left from right hemisphere
longitudinal fissure
broca’s area of brain associated with what?
associated with speaking. (if cant speak during stroke this area effected)
aphasia=
speaking problems
sensory memory
somatosensory
Pain and Temperature Touch and Proprioception Primary cortex: postcentral gyrus Contralateral Association cortex: adjacent sensory memory Phantom Limb Syndrome what cortex?
somatosensory cortex
Voluntary motor commands
Primary motor cortex: UMN -precentral gyrus
Association cortex: adjacent motor memory
Contralateral
Homunculus:
From Corpus Callosum to Lateral fissure
what cortex is this?
motor cortex
Primary visual cortex: Occipital pole
Retinotopic Map
Secondary: Adjacent Orientation, Spatial frequency, color Tertiary: Adjacent Motion, recognition what cortex is this?
Visual cortex
Superior Temporal Gyrus Primary cortex Input: frequency, amplitude, timing Association cortex Memory, pitch, harmony, chords what cortex is this?
auditory cortex
what are fissures?
Divisions between lobes
what are gyri?
convulusions on surface of brain
what are sulcus?
grooves between gyri in brain.
