Random Review NEUROMUSCULAR Flashcards
(405 cards)
To use visual system for balance…
eyes have to be open
To use proprioception for balance…
something like foam can’t be present because it makes the input info unreliable
To use the vestibular system for balance…
the neurological and mechanical aspects of this system can’t be compromised
How does the knowledge of results affect motor learning?
- Knowledge of results should be kept minimal
- Patients should be encouraged to engage in retrieval processes and maintain focus on performance
Function of the frontal lobe
- Voluntary movement
- Intellect
- Orientation
- Broca’s area (usually left hemisphere): speech, concentration
- Personality, temper, judgement, reasoning, behavior, self-awareness, executive function
Function of parietal lobe
- Sensation of touch, kinesthesia, vibration, temperature
- Receives info from other areas of the brain about hearing, vision, motor, sensory, and memory
- Provides meaning for objects
- Interprets language and words
- Spatial and visual perception
Function of temporal lobe
- Primary auditory processing and olfaction
- Wernicke’s area (usually left hemisphere): understand and produce meaningful speech
Function of occipital lobe
- Process visual info
- Process color, light, and shape
- Judgement of distance
- See in 3D
Impairments of frontal lobe
- Contralateral weakness
- Perseveration, inattention
- Personality changes, antisocial behavior
- Impaired concentration, apathy
- Broca’s aphasia (expressive deficits)
- Delayed or poor initiation
- Emotional lability
Impairments of parietal lobe
- Dominant hemisphere –> agraphia, alexia, agnosia
- Non-dominant hemisphere –> dressing apraxia, constructional apraxia, anosognosia
- Contralateral sensory deficits
- Impaired language comprehension
- Impaired taste
Impairments of temporal lobe
- Learning deficits
- Wernicke’s aphasia (receptive deficits)
- Antisocial, agressive behaviors
- Difficulty w/ facial recognition
- Difficulty w/ memory, memory loss
- Inability to categorize objects
Impairments of the occipital lobe
- Homonymous hemianopsia
- Impaired extraocular muscle movement and visual deficits
- Impaired color recognition
- Reading and writing impairment
- Cortical blindness w/ bilateral lobe involvement
Function of hippocampus
Memory
Function of basal ganglia
- Voluntary movement
- Regulation of autonomic movement
- Posture
- Muscle tone
- Control of motor responses
Function of amygdala
Emotional and social processing
Thalamus
Relay or processing station
Hypothalamus
- Receives and integrates info from the ANS
- Regulates hormones
- Controls hunger, thirst, sexual behavior, and sleeping
Subthalamus
Regulating movements produced by skeletal muscles
Epithalamus
- Pineal gland
- Secretes melatonin
- Controls internal clock
Blood supply of anterior cerebral arterey
- Anterior frontal lobe
- Medial surface of frontal and parietal lobe
Blood supply of middle cerebral artery
- Most of outer cerebrum
- Basal ganglia
- Posterior and anterior internal capsule
- Putamen
- Pallidum
- Lentiform nucleus
Blood supply of posterior cerebral artery
- Portion of midbrain
- Subthalamic nucleus
- Basal nucleus
- Thalamus
- Inferior temporal lobe
- Occipital and occipitoparietal cortices
Blood supply of vertebral-basilar artery
- Lateral aspect of pons and midbrain together w/ superior cerebellum
- Cerebellum
- Medulla
- Pons
- Midbrain and thalamus
- Occipital cortex
Expected impairments from injury to anterior cerebral artery
- Contralateral LE motor and sensory involvement
- Loss of bowel and bladder control
- Loss of behavioral inhibition
- Significant mental changes
- Neglect
- Aphasia
- Apraxia and agraphia
- Perseveration
- Akinetic mutism w/ significant bilateral involvement
