When you access a sub-object level on the Polygon Modeling panel, a corresponding contextual panel with controls for editing at that level opens on the ribbon. The sub-object panels are:

[Sub-object] Panels
Topics in this section
- Vertices Panel
Vertices are points in space: They define the structure of other sub-objects (edges and polygons) that make up the poly object. When you move or edit vertices, the connected geometry is affected as well. Vertices can also exist independently; such isolated vertices can be used to construct other geometry but are otherwise invisible when rendering. - Edges Panel
An edge is a line connecting two vertices that forms the side of a polygon. An edge can't be shared by more than two polygons. Also, the normals of the two polygons should be adjacent. If they aren't, you wind up with two edges that share vertices. - Border Edges Panel
A border is a linear section of a mesh that can generally be described as the edge of a hole. This is usually a sequence of edges with polygons on only one side. For example, a box primitive doesn't have a border, but the teapot object has several: on the lid, on the body, on the spout, and two on the handle. If you create a cylinder and then delete an end polygon, the adjacent row of edges forms a border. - Polygons/Elements Panel
A polygon is a closed sequence of three or more edges connected by a surface. Polygons provide the renderable surface of editable poly objects. An element is a group of contiguous polygons.
