A misspelling or variant of 'cerebella,' the plural of cerebellum, the part of the brain that controls balance and coordination.
This appears to be an archaic or erroneous spelling of 'cerebella,' which comes from Latin 'cerebellum' (little brain), diminutive of 'cerebrum' (brain).
This is a fun reminder that spelling standardization is recent—older medical texts used many variations before everyone agreed on 'cerebella' as the correct plural!
