Defining organelle of the eukaryotic cell; a membrane limited body which contains chromosomes and one or more nucleoli; 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.CRISP ThesaurusNational Institutes of Health, 2006
-
Organelle which has as its direct parts a nuclear membrane and nuclear matrix.Foundational Model of AnatomyUniversity of Washington, 2017

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 & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
