pons and contains sensory fibers

28
Q

the cerebellum connects to what throught the inferior cerebellar peduncle

A

medulla oblongata and the spinal cord and ocntains sensory and motor axons

29
Q

function of teh cerebellum

A

the coordination of skeletal muscle contraction
may have a role in cognition and language processing
regulating posture and balance

30
Q

signs and symptoms of cerebellar disease

A

1) ataxia
2) gait ataxia
3) hypotonia
4) intention tremor
5) nystagmus
6) dysmteria

8) dysdiadochokinesia
9) siorders of speech ( dysarthria)
10) decomposition of movement

30
Q

what is the decomposition of movement

A

ability to carry out moto movement but in a component of motions ( not smoothly carried out)

31
Q

what is the rebound phenomenon

A

over shooting of movement when resistenace is suddenly removed
