Functional areas of Brain Flashcards
Frontal lobe
Pre-central gyrus
primary motor area
Frontal lobe
lateral surface
Broca motor speech area
Frontal lobe
Medial surface
Cingulate gyrus
- emotional aspects of behavior
Frontal lobe
Prefrontal association areas
emotion, motivation, personality, social inhibition
Parietal lobe
somatosensory function
Parietal lobe
Post central gyrus
primary somatosensory area
Parietal lobe
lateral and medial surface
Pain, touch, limb position
Parietal lobe
left lateral surface
Wernicke Area
- sensory aspects of language
occipital lobe
visual info
occipital lobe
calacrine sulcus
on medial surface
-on either side are primary visual areas
occipital lobe
visual association areas
mediate seeing and recognition
temporal lobe
auditory information
temporal lobe
superior temporal gyrus
ability to hear and process what is heard
temporal lobe
lateral surface
perception of language
temporal lobe
Anterior/medial surfaces
learning, memory, emotion
Basal ganglia
initiate and control voluntary movement
smooth out motor movements
Limbic structures
drive, emotion, learning, memory
Association fibers
within same hemisphere
commissural fibers
to similar area in other hemisphere
thalamus
gatekeeper for cortex
-processes sensory (except for olfactory)> motor info on way to cortex
hypothalamus
integrates endocrine, autonomic function
Superior colliculus
visual reflexes
inferior colliculus
auditory reflexes
cerebral aqueduct
connect 3rd and 4th ventricle
pyramids
contain descending corticospinal fibers
olives
contain olivary nuclear complex (modulates motor activity
ventricular foramen of monro
connects 3rd to lateral
aqueduct of sylvius/ cerebral aqueduct
connects 3rd and 4th ventricles
lateral foramen of luschka
4th vent to subarachnoid
medial foramen of magendie
4th vent to subarachnoid
CSF goes from arachnoid granulations into
Superior sagittal sinus
innervation of dura mater
CN V and X
extradural/epidural hematoma
middle meningeal artery
subdural hematoma
vein (shaken baby)
subarachnoid hematoma
cerebral arteries and veins
Corticospinal tract
(pyramidal tract)
purely motor
spinothalamic tract
purely sensory for pain/temp
posterior (dorsal) column
purely sensory for vibration/position sense
P-gp inhbitors
Vera CAN QUIt -Verapamil cyclosporin amiodarone nifedipine Quinidine
Brodmann area 4
primary motor cortex (precentral gyrus)
Brodmann area 6
Premotor cortex and supplementary motor cortex
Broadman area 3,1, 2
primary somatosensory cortex
premotor area/ motor association area
leaned movements, voluntary/planned movements-
- lesion = can’t brush teath
somatosensory association areas
interpret significance of sensory input
-lesion = cant recognize object in hand
visual association area
interprets what we see
- visual agnosia = cant recognize objects in opposite visual field
Lesion in right posterior parietal cortex
contralateral neglect syndrome
Agnosia
can’t recognize objects
- temporal lobe defect
arcuate fasiculus
connects language centers
Vestibulocerebellum structures and function
vestibular nuclei, fastigial nuclei, floccolonodular lobe, inferior paravermis
- balance, stability, head/neck/eye movement
spinocerebellum
anterior lobe, vermis, paravermis
- coordinate trun kand proximal limb movement
cerebrocerebellum
lateral posterior lobe
- fine motor planning of limbs, anticipates consequences of movements
