20
Q

Hipotonia

A

diminuição do tónus muscular

21
Q

função vestibular

A
  • maintains balance
  • awareness of the body’s spatial orientation
  • afferent and efferent vestibular pathwaysThe vestibular nuclei receive afferents and integrate input from the vestibular system of :
    • the inner ear
    • the visual and somatic sensory systems
    • the cerebellum
    Efferents from these nuclei extend to the thalamus, cerebellum, visual motor, and descending motor systems to facilitate balance and the coordination of movement
22

A

paresthesia → abnormal sensation
tato levo

23
Q

dysesthesia

A

dysesthesia→ spontaneous or evoked abnormal unpleasant sensation
ao tato levo

24
Q

Hypesthesia

A

hypesthesia → decreased perception of sensory stimuli
