Name:	endocrine pancreas
Synonyms:	pancreatic islet, tail pancreas

Name:	lacks parts or has fewer parts of type
Synonyms:	loss of
Definition:	The bearer of this quality has_part < n of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. This case includes the limit case, where the bearer lacks all parts of the specified type.
