Neuromuscular: Central Nervous System Flashcards
Frontal lobe function
Voluntary movement, intellect, orientation
Broca’s Area (Left): speech, concentration
Personality, temper, judgement, reasoning, behavior, self-awareness, executive function
Frontal lobe impairment
Contralateral weakness perseveration, inattention Personality changes, antisocial behavior Impaired concentration, apathy Broca's aphasia (expressive deficits) Delayed or poor initiation Emotional lability
Parietal lobe function
Associated with sensation of touch, kinesthesia, perception of vibration, and temperature
Receives info from other areas of the brain regarding hearing, vision, motor, sensory, and memory
Provides meaning for objects
Interprets language and words
Spatial and visual perception
Parietal lobe impairments
Dominant hemisphere (typically left): agraphia, alexia, agnosia
Non-dominant hemisphere (typically right): dressing apraxia, constructional apraxia, anosognosia
Contralateral sensory deficits
Impaired language comprehension
Impaired taste
Temporal lobe function
Primary auditory processing and olfaction
Wernicke’s area (left hemisphere): ability to understand and produce meaningful speech, verbal and general memory, assists with understanding language
The rear of the temporal lobe enables humans to interpret other people’s emotions and reactions
Temporal lobe impairment
Learning deficits Wernicke's aphasia (receptive deficits) Antisocial, aggressive behaviors Difficulty with facial recognition Difficulty with memory, memory loss Inability to categorize objects
Occipital lobe function
Main processing center for visual information
Processes visual information regarding colors, light, and shapes
Judgement of distance, seeing in three dimensions
Occipital lobe impairment
Homonymous hemianopsia
Impaired extraocular muscle movement and visual deficits
Impaired color recognition
Reading and writing impairment
Cortical blindness with bilateral lobe involvement
Meningitis signs and symptoms
Fever, headache, vomiting
Complaints of a stiff and painful neck, nuchal rigidity
Pain in the lumbar area and posterior thigh
Brudzinski’s sign (flexion of the neck facilitates flexion of the hips and knees)
Kernig’s sign (pain with hip flexion combined with knee extension)
Sensitivity to light
Signs of hydrocephalus or a blocked shunt include:
Enlarged head or bulging fontanelles in infants Headache Changes in vision Large veins noted on scalp Behavioral changes Seizures Alteration in appetite, vomiting "Sun setting" sign or downward deviation of the eyes Incontinence
