This tab shows SNOMED CT’s taxonomy view. Free browsing through parent-child hierarchies is allowed by clicking ‘greater than’ icon. Clicking on any concept will select it on the right panel. Also, selecting any yellow circle in the taxonomy and dragging it into the Concept Summary tab in the right panel (concept area will become yellow when dragging a concept into it) will show th selected concept on the right.
The left panel displays the whole SNOMED CT hierarchy, starting by SNOMED CT Concept, the top level concept. Each hierarchy can be easily unfolded to display the concepts it contains. One way to search for a particular concept is by scrolling up and down the hierarchies manually. Another way to find a concept is explained in the Search Tab.
