There are a lot of items displayed in the Maya user interface which are as follows: 

1. Menu Bar: The Main Menu bar appears at the top of the Maya interface directly below the Maya title bar and displays the chosen menu set. Each menu set corresponds to a module within Maya: Animation, Polygons, Surfaces, Rendering, and Dynamics. Modules are a method for grouping related features and tools. 

2. Status Line: The Status Line, located directly below the Main Menu bar, contains a variety of items, most of which are used while modeling or working with objects within Maya. Many of the Status Line items are represented by a graphical icon. The icons save space in the Maya interface and allow for quick access to tools used most often. 

3. Shelf: The Shelf is located directly below the Status line. The Maya Shelf is useful for storing tools and items that you use frequently or have customized for your own use. You can keep the tools and items you use most frequently in a location that provides handy access. Maya has some of the Shelf items pre-configured for your use.

4. Workspace: The Maya workspace is where you conduct most of your work within Maya. The workspace is the central window where your objects and most editor panels appear.

• The panel is labeled persp at the bottom to indicate that you are viewing the Maya scene from a perspective camera view. 
• The panel has its own menu bar at the top left corner of the panel. These menus allow you to access tools and functions related to that specific panel. 
• The grid is displayed with two heavy lines intersecting at the center of the Maya scene. This central location is called the origin. The origin is the center of Maya’s 3D world, and with all object’s directional values measured from this location.

5. Channel Box: The Channel Box is the primary, fastest, and most streamlined tool for editing object attributes. It lets you quickly change attribute values, set keys on keyable attributes, lock or unlock attributes, and create expressions on attributes.
