What are the three parts of the Brainstem?
- 1- midbrain
- 2- pons
- 3- medulla
What is a collection of nuclei?
What is a collection of ganglia in close communication with the cortex?
What is functionally involved with the grading of movement and adjusting movement strategies?
involved with eye movement and balance
lesions in this area can produce problems in gait and conjugate eye movements
involved with the control of the trunk and proximal muscles of arms and legs
grading of movements and adjusting movements to meet the task demands
pontocerebellum ( cerebrocerebellum)
what four nuclei receive both inhibitory and excitatory input?
interpositus- emboliform and globose
Three cerebellar peduncles which contain the afferent and efferent fibers
- superior peduncle
- middle peduncle
- inferior peduncle
major pathway for output of the cerebellum to other structures.
efferent fibers go to red nucleus, thalamus and medulla
premotor cortex to support motor planning
comprised of afferent fibers projecting into the cerebellum from the sensory and motor regions of the cerebral cortex, the largest of cerebellar peduncles
carries both afferent and efferent fibers involved with integrating proprioceptive information
contains the dendritic branches of the purkinje cells along with stellate and basket cells
outer molecular layer of the cerebellar cortex
cell bodies of the purkinje cells, this layer is sometimes refered to as the prkinje layer
middle portion of cerebellar cortex
contains granule cells and often is labeled as the Granular layer
inner layer of cerebellar cortex
