Cerebellum Flashcards
What are the lobes of the cerebellum?
Anterior
Posterior
Flocculonodular
What are the fissures of the cerebellum?
Primary
Posterolateral
What are the regions of the cerebellum?
Vermis (medial)
Paravermis (intermediate)
Hemisphere (lateral)
The superior cerebellar peduncle is in charge of
Output from cerebellum to the ventral lateral nucleus of the thalamus and red nucleus of the midbrain
The middle cerebellar peduncle is in charge of
Input from the pons
The inferior cerebellar peduncle is in charge of
Input from the spinal cord and medulla
Input/output from/tp vestibular nuclei
The superior cerebellar artery supplies
Superior portion of cerebellum including vermis, paravermis, hemisphere, superior and middle cerebellar peduncles
AICA supplies
Lateral inferior portion of the cerebellum including hemisphere, flocculus, middle cerebellar peduncle
PICA supplies
Medial inferior portion of cerebellum including vermis, paravermis, nodulus, inferior cerebellar peduncle
What are the layers of the cerebellar cortex?
Molecular layer
Purkinje layer
Granular layer
Subcortical white matter
Climbing fibers send signals/excite …. in the cerebellum
Purkinje cells
The cell bodies of climbing fibers are found in …. axons are found in ….
Cell bodies: Inferior olivary nucleus
Axons: inferior cerebellar peduncles
Mossy fibers send signals/excite …. which then excites
Granule cells which excite Purkinje cells
The cell bodies of mossy fibers are found in …. axons are found in ….
Cell bodies: pontine nuclei, vestibular nuclei, spinocerebellar tracts
Axons: all three cerebellar peduncles
The fastigial nucleus of the cerebellum receives input from
Purkinje cells of vermis and flocconodular lobe (medial zone)
