Detailed Descriptions for the elements in the BodyStructure resource.
| BodyStructure | |
| Element Id | BodyStructure | 
| Definition | Record details about an anatomical structure. This resource may be used when a coded concept does not provide the necessary detail needed for the use case.  | 
| Cardinality | 0..* | 
| Type | DomainResource | 
| Alternate Names | anatomical location | 
| Summary | false | 
| BodyStructure.identifier | |
| Element Id | BodyStructure.identifier | 
| Definition | Identifier for this instance of the anatomical structure.  | 
| Note | This is a business identifier, not a resource identifier (see discussion) | 
| Cardinality | 0..* | 
| Type | Identifier | 
| Summary | true | 
| BodyStructure.active | |
| Element Id | BodyStructure.active | 
| Definition | Whether this body site is in active use.  | 
| Cardinality | 0..1 | 
| Type | boolean | 
| Is Modifier | true (Reason: This element is labelled as a modifier because it is a status element that can indicate that a record should not be treated as valid) | 
| Meaning if Missing | This resource is generally assumed to be active if no value is provided for the active element | 
| Requirements | Need to be able to mark a body site entry as not to be used because it was created in error.  | 
| Summary | true | 
| Comments | This element is labeled as a modifier because it may be used to mark that the resource was created in error.  | 
| BodyStructure.morphology | |
| Element Id | BodyStructure.morphology | 
| Definition | The kind of structure being represented by the body structure at   | 
| Cardinality | 0..1 | 
| Terminology Binding | SNOMED CT Morphologic Abnormalities (Example) | 
| Type | CodeableConcept | 
| Summary | true | 
| Comments | The minimum cardinality of 0 supports the use case of specifying a location without defining a morphology.  | 
| BodyStructure.location | |
| Element Id | BodyStructure.location | 
| Definition | The anatomical location or region of the specimen, lesion, or body structure.  | 
| Cardinality | 0..1 | 
| Terminology Binding | SNOMED CT Body Structures (Example) | 
| Type | CodeableConcept | 
| Summary | true | 
| BodyStructure.locationQualifier | |
| Element Id | BodyStructure.locationQualifier | 
| Definition | Qualifier to refine the anatomical location. These include qualifiers for laterality, relative location, directionality, number, and plane.  | 
| Cardinality | 0..* | 
| Terminology Binding | Bodystructure Location Qualifier (Example) | 
| Type | CodeableConcept | 
| Summary | false | 
| BodyStructure.description | |
| Element Id | BodyStructure.description | 
| Definition | A summary, characterization or explanation of the body structure.  | 
| Cardinality | 0..1 | 
| Type | string | 
| Summary | true | 
| Comments | This description could include any visual markings used to orientate the viewer e.g. external reference points, special sutures, ink markings.  | 
| BodyStructure.image | |
| Element Id | BodyStructure.image | 
| Definition | Image or images used to identify a location.  | 
| Cardinality | 0..* | 
| Type | Attachment | 
| Summary | false | 
| BodyStructure.patient | |
| Element Id | BodyStructure.patient | 
| Definition | The person to which the body site belongs.  | 
| Cardinality | 1..1 | 
| Type | Reference(Patient) | 
| Summary | true |
