MeSH definition : Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one
or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type
membrane which is perforated by a number of pores; the outermost membrane is continuous
with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton
