CEREBELLUM
basic horizontal and vertical arrangement
CORTEX AND CEREBELLAR NUCLEI
Medial zone - cortex covering vermis + ncll. fastigii
Paramedial zone - paramedial cortex + ncll. emboliformes et globosi
Lateral zone – lateral cortex + ncl. dentatus
Gray mater (cortex + ncll.) and white mater (including pedunculi cerebellares)

• basic significance for maintenance of balance - trr. vestibulospinales
• influence to lower motoneurons for axial muscles
• a role during control of eye movement and their coordination with movement
of head
FUNCTION SPINAL CEREBELLUM – MEDIAL ZONE
• control of axial muscles at keeping of upright posture through cortex and
tr. corticospinalis ant.
FUNCTION OF SPINAL CEREBELLUM - PARAMEDIAL ZONE
• control of spinal cord motoneurons for distal muscles of extremities through
cortex and tr. corticospinalis lat.
FUNCTION OF PONTOCEREBELLUM
• control of motor planning and target movement
• non-motor function (cognition) - solution of problem and linguistics phrasing
FUNCTION OF VESTIBULAR CEREBELLUM
