Head , Nervous System, Face Flashcards
unpaired skull bones
frontal, occipital, sphenoid, ethmoid, vomer, mandible
junction of frontal + temporal + parietal + greater wing of sphenoid
pterion
junction of parietomastoid + occipitomastoid + lambdoid
asterion
junction of coronal + sagittal suture
bregma = bandang harap
future site of ant fontanelle
closes at 18 mos
junction of lambdoid + sagittal suture
Lambda = likod
future site of post fontanelle
closes first few months after birth
3 primary brain vesicles and divisions
- Prosencephalon ➝ telencephalon & diencephalon
- Mesencephalon (no division)
- Telencephalon ➝ metencephalon & myelencepalon

Presentation of ACA stroke
motor and sensory cortices of lower limb
CL paralysis and sensory loss of lower limb
Presentation of MCA stroke
motor and sensory cortices of upper limb and face, temporal lobe, and frontal lobe
CL paralysis and sensory loss of upper limb
If stroke in dominant hemisphere = aphasia
nondominant=hemineglect
Presentation of PCA stroke
occipital lobe
CL hemianopsia with macular sparing
VPM thalamic nuclei transmits
sensory
VPL and ventral anterior transmits
motor
anterior thalamic nuclei transmits
emotional tone and memory
Central pain syndrome due to thalamic infarction aka
Dejerine-Roussy syndrome
cerebellar lobe which maintains coordination of limb movements and for regulation of muscle tone
Anterior lobe
cerebellar lobe which functions for coordination of voluntary movements
posterior lobe
cerebellar lobe for equilibrium
floculonodular lobe
heel to din test tests integrity of what cerebellar lobe
anterior
