Cerebellum Flashcards
What is the integrating center for postural information and regulates movement and posture indirectly by adjusting the output of the major descending motor systems of the brain?
Cerebellum
What results in the reduction of strength and speed of movement and results in the loss of the ability to contract individual muscles
damage to motor cortex
Where is the anatomical region of the vestibulocerebellum?
floconodular lobe
Where is the anatomical region of the spinocerebellum?
vermis: fastigial nucleus
intermediate hemisphere: interposed nucleus
Where is the anatomical region of the neocerebellum?
lateral hemisphere: dentate nucleus
What side of the body would you see signs when there is a lesion to the 3 sagittal bands of the cerebellum?
Ipsilateral side of body
What zone damage is associated with disorders of equilibrium and eye movement?
Vermal zone
With Vermal zone damage, what is the syndrome called with probems maintaining equilibrium without limb ataxia,
hypotonia, or tremor?
Floconodular lobe syndrome
What zone damage is associated with altered patterns of muscle movement and is known as
Paranormal zone
With Paranormal zone damage, what is the syndrome called with increased postural reflexes and seldomly seen in humans?
anterior lobe syndrome
What zone damage is is associated with initiation of coordinated movements?
Lateral zone
With Lateral zone damage, what syndrome is characterized by limb ataxia & hypotonia?
neocerebellar syndrome
What complication must be questioned when vomiting occurs without nausea, is projectiles, and occurs during movement?
Cerebellar tumor (3P syndrome)
What is known as movements have an irregular wavering course that seems to consist of continuous overshooting, overcorrecting, and then overshooting again around an intended trajectory (disorder of contraction of agonist and antagonist muscles)?
ataxia
What is the cardinal sign of a cerebellar lesion?
ataxia and hypotonia
