. Q1 Concerning the cerebellum:
a. paleocerebellum is facilitatory to muscle tone
b. each cerebellar hemisphere acts on the contralateral muscles
c. spinocerebellar tracts give rise to conscious recognition of joint position sense
d. neocerebellum helps planning of voluntary movements

.  Q2 The cerebellum:
a. initiates the skilled voluntary movements
b. lesion is accompanied by severe hypertonia on the same side
c. has no role in maintenance of equilibrium
d. compares the performance of movement with cortical orders

Q3 All the following statements about the cerebellum are correct, except
a. cortico-pontocerebellar fibers pass through the middle cerebellar peduncle
b. cerebellar lesion of one side produces abnormalities of movements on the ipsilateral side of the body
c. the spinocerebellum provides the planning and timing function of voluntary movements
d. cerebellar lesion produces decomposition of voluntary movement

Q4:Concerning the functions of the cerebellum the following statements are true, except
a. the cerebellum co-ordinates the muscle contractions required to execute a movement
b. the cerebellum directly stimulates motor neurons required to make a movement
c. the cerebellum receives feedback from muscles that execute the movement
d. the cerebellum is involved in the planning of a movement

Q5:A patient who presents with an intention tremor, "past pointing", and a"drunken" gait might be expected to have a lesion involving the
a. cerebellum
b. medulla
c. basal ganglia
d. eighth cranial nerve

Q6 Neocerebellar syndrome is characterized by:
a. hypertonia
b. mask face
c. dysdiadokinesia
d. static tremors

Q7: Loss of braking function of cerebellum leads to:
c) drunken gait.
a) staccato speech.
d) kinetic tremors.
b) hypotonia.
e) dysmetria.

Q8:Braking function of cerebellum
a) is carried mainly by archicerebellum.
c) is carried mainly by paleocerebellum.
e) when lost leads to dysdiadokinesia.
b) stops the moved part at the intended point.
d) inhibits oscillation in movements
Q9: Cerebellar ataxia is
a) characterized by static tremors.
c) characterized by vertigo
e) caused by lesion in archicerebellum,
b) caused by lesion in paleocerebellum.
d) characterized by dysdiadokinesia.

Q10: Which of the following is a manifestation of cerebellar ataxia:
a) static tremor.
b) dysdiadokinesia.
c) akinesia.
d) shuffling gait.
e) vertigo.

Q11: Dysmetria:
a) is a manifestation of parkinsonism.
c) results from stimulation of crista ampullaris.
e) is a manifestation of paleocerebellum.
b) means failure to do rapid alterating movement.
d) is a manifestation of neocerebellar lesion
