TERM 1
3 Functions of Cerebellum
DEFINITION 1
1. Proprioception 2. Equilibrium/Balance 3. Coordination of
motor movements - controls speed, force, and duration of
movements
TERM 2
Flocculonodular Lobe
DEFINITION 2
The flocculonodular lobe is a lobe of the cerebellum
consisting of the nodule and the flocculus.
TERM 3
Flocculonodular Lobe (anatomical name)
DEFINITION 3
- vestibulocerebellum [Archicerebellum] = Equilibrium A.
Receives information from the inner ear (vestibular nuclei)
for BALANCE B. Flocculonodular lobe C. Fastigal nucleus
TERM 4
Anterior Lobe (anatomical name)
DEFINITION 4
- Spinocerebellum [Paleocerebellum] (Spinocerebellar Tracts)
A. Receives information from the accessory cuneate nucleus
and the nucleus dorsalis for unconscious proprioception B.
Mainly anterior lobe and medial part of posterior lobe C.
Interposed nuclei= globose and emboliform nuclei
TERM 5
Posterior Lobe (anatomical name)
DEFINITION 5
- Pontocerebellum [Neocerebellum] A. Receives information from
pre-motor area (area 6), the postcen tral gyrus (areas 3,1,2) and
the association areas through the po ntine nuclei for planning and
timing of sequential movements. In s hort, to control the speed,
force, and duration of movements. B. Mainly posterior lobe and
lateral part of anterior lobe C. D entate nucleus

Flocculonodular Lobe

DEFINITION 2 The flocculonodular lobe is a lobe of the cerebellum consisting of the nodule and the flocculus. TERM 3

Flocculonodular Lobe (anatomical name)

DEFINITION 3

  • vestibulocerebellum [Archicerebellum] = Equilibrium A. Receives information from the inner ear (vestibular nuclei) for BALANCE B. Flocculonodular lobe C. Fastigal nucleus TERM 4

Anterior Lobe (anatomical name)

DEFINITION 4

  • Spinocerebellum [Paleocerebellum] (Spinocerebellar Tracts) A. Receives information from the accessory cuneate nucleus and the nucleus dorsalis for unconscious proprioception B. Mainly anterior lobe and medial part of posterior lobe C. Interposed nuclei= globose and emboliform nuclei TERM 5

Posterior Lobe (anatomical name)

DEFINITION 5

  • Pontocerebellum [Neocerebellum] A. Receives information from pre-motor area (area 6), the postcentral gyrus (areas 3,1,2) and the association areas through the pontine nuclei for planning and timing of sequential movements. In short, to control the speed, force, and duration of movements. B. Mainly posterior lobe and lateral part of anterior lobe C. Dentate nucleus
