Navigational concept	SNOMED CT Glossary: A hierarchical view of a set of SNOMED CT concepts that is intended to assist navigation at the user interface . Note: There are several differences between navigation hierarchies and the formal subtype hierarchy : Links between concepts in a navigation hierarchy are represented by an [see 4.2.2. Ordered Reference Set ] Navigation links do not contribute to the semantic definitions of concepts . Therefore, the criteria for creating a navigation hierarchy can be based on arbitrary criteria relating to usability; A navigation hierarchy may specify the order in which a set of concepts are to be displayed when nested under another specified concept .
Navigational link	An association between two Concepts that supports Navigation between Concepts. Such links may involve one of more Navigational Concept but are not required to. Navigation Links generate a hierarchy which has three distinct differences from the subtype hierarchy defined by \| is a \| Relationship. A navigational hierarchy: Does not contribute to the semantic definitions of Concepts; Specifies a display order for Concepts within a navigational siblingset of Concepts linked to a common parent. Navigation Links are distributed as a Navigation Subset. Alternative Navigation Subsets may be specified and applied to vary the navigation hierarchy to meet the needs of particular groups of users.
Navigational subset	A Subset that specifies sets of Navigation Links between Concepts together with a display sort order. The set of Navigational Links in a Navigational Subset encodes an arbitrarily defined mono– or polyhierarchical organisation of the concepts referenced within. The set of concepts so organised may be any mixture of active and inactive concepts, and may or may not include any Navigational Concepts. The semantics of Navigation Links between concept pairs need be neither explicit nor constant across the Navigational Subset as a whole, though the mechanism does not preclude its use to encode a formally specified and computable hierarchy.
Body cavity	The collective visceral cavity of the trunk (thoracic cavity plus abdominopelvic cavity), bounded by the superior thoracic aperture above, the pelvic floor below, and the body walls (parietes) in between.
