Cerebellum Flashcards
Restiform body + juxtarestiform body
Connects cerebellum and medulla
Inferior cerebellar peduncle
Connects cerebellum and pons
Afferent fibers originating in the contralateral basal pons
Middle cerebellar peduncle
Brachium pontis
Connects cerebellum and midbrain
Conveys primarily efferent fibers that originate in the deep cerebellar nuclei–>specific nuclei of thalamus and other areas in the brainstem
Also has some afferent pathways that come into the cerebellum through the superior cerebellar peduncle
Superior cerebellar peduncle
Lateral zone
Dentate nucleus
Intermediate zone
Globose and emboliform nuclei
Medial zone
Fastigial nucleus
Supplies posterior-inferior cerebellum, restiform body, 4th ventricle
PICA
Caudal parts of middle cerebellar peduncle, caudolateral portions of inferior cerebellar surface, parts of dentate nucleus
AICA
Superior surface of cerebellum, most of cerebellar nuclei, anterior parts of middle cerebellar peduncle and superior cerebellar peduncle
SCA
Outermost layer, contains cell processes and stellate and basket cells
Molecular layer
Single row of very large cells; contains only efferents within the cerebellar cortex; release GABA, causing waxing and waning inhibitory effect
Purkinje cell layer
Deepest layer, contains granule cells and Golgi cells
Granule cell layer
