neuro conditions exam 2 Flashcards
frontal lobe responsible for
voluntary movement and judgment, memory for language, personality and broca’s area motor speech control
damage to parietal lobe results in difficulties with
auditory and visual discrimination
cerebellum is responsible for
coordinating muscle movement timing and force
An ACA stroke primarily affects
motor and sensory areas for leg and foot
motor planning areas- prefrontal cortex
temporal lobe responsible for
memory emotions recpetive language, auditory adn visual discrimnation, ability to recognize faces; perception of written language
parietal lobe functions
attention, behavior, praxis, spatial relations, tactile discrimnation, reflexive responses to pain adn temperature
occipital lobe
vision and perception
brainstem functions
autonomic functions; heartbeat respiration blood pressure/flow; perpsiration, arousa, sleep, reflexive actions- gagging, vomiting, swallowing coughing
likely affected by MCA stroke
motor and sensory areas for the face, trunk, arm adn hand
lobe involved in tactile discrimnation and spatial relations
temporal
condition often leads to increased muscel tone and hyoertonia
spasticity
damage to brainstem likely to impact
heartbeat and respiratory functions
MCA- middle cerebral artery
primary motor and sensory cortices for face, trunk, arm and hand; impacts frontal and parietal lobe; optic radiations (visual tract); corticobulbar and corticospinal tracts; basal ganglia
ACA- anterior cerebral artery
primary motor and sensory cortices for leg and foot; motor planing areas prefrontal cortex
PCA posterior cerebral artery
primary visual areas; optic radiations (visual tract) ; temporal lobe; multimodal association areas (sensory relay )
anterior cord syndrome
loss of motor control, diminished pain and temp /////
pressure and joint sensation, proprioception, vibrations and fine touch are kept
posterior/ dorsal cord injury
loss of fine touch, vibration and decreased proprioceptions// intact pain adn temperature
central cord syndrome
loss of pain adn temperature // loss of functions in UEs more than LEs
cuneocerebellar tract and rostral spinocerebellar tract lesion
ipsilateral UE and trunk proprioceptions
ACA lesions
contralateral LE sensory loss
MCA lesions
contralateral sensory loss of UE, LE and face
brown-sequard syndrome
loss of touch, vibration and proprioception ipsilaterally
loss of pain and temp contralaterally
upper motor neuron
pareisis or plegia; spasticity; hypertonocity; hyperreflexia; postive banbinskis sign
Lower motor neuron problem
flaccidity ; fibrillations or fasiculations; hypotonia; hypo- or areflexia
