Correct, Latest 2024/2025.
frontal lobe function
executive functions (concentration, thinking, problem solving, judgement)
parietal lobe function
understanding language and process sensory information
occipital lobe function
visual processing
temporal lobe function
- fight or flight
- STM
- understanding words and directions
brainstem function
metabolic functions (supplied by basilar artery)
cerebellum function
balance and coordination
order of ventricular flow
- CSF produced by choroid plexus
- lateral ventricles
- interventricular foramen
- third ventricle
- cerebral aquaduct
- fourth ventricle
- median (foramen of Magendie) and lateral (foramen of Lushka apertures
- subarachnoid space
order of venous drainage
- superior sagittal sinus
- inferior sagittal sinus
- straight sinus
- transverse sinus
- sigmoid sinus
- internal jugular vein
types of cortical neurons and their functions
GRANULE CELLS: remain in cortex
PYRAMIDAL CELLS: travel through white matter
, - Projection fibers (vertical - internal capsule)
- Commisural fibers (horizontal - corpus callosum)
- Association fibers (connect cortical regions)
pyramidal system
corticobulbar and corticospinal tracts
extrapyramidal system
responsible for motor control of activities (modulating and regulating movement and coordination)
order of arterial supply
- vertebral
- PICA (posterior inferior cerebellar)
- AICA (anterior inferior cerebellar)
- basilar
- superior cerebellar
* - posterior cerebral
* - posterior communicating
* - middle cerebral / internal carotid
* - anterior cerebral 1
* - anterior communicating
- anterior cerebral 2
LEFT hemisphere lesion : signs and symptoms
- affects right side
- difficulty understanding and producing language
- cautious behavior, hesitant, depression
- loss of logical processing
RIGHT hemisphere lesion : signs and symptoms
- affects left side
- unable to comprehend speech
- unable to recognize faces or places (left neglect)
- impulsive behavior, unaware
- loss of holistic processing (pictoral)
Brainstem pathway : medial structures
- motor nuclei of CN 3, 4, 6, and 12
- motor tract (corticospinal)
- medial longitudinal fasciculus (coordinates head and eye movement at the same time)
- medial lemniscus (light touch and proprioception)
Brainstem pathway : lateral structures
- sympathetic tract
- spinothalamic tract (fast nocioception and temperature)
- sensory tract of trigeminal nerve
- spinocerebellar tract (unconscious proprioception)
