The Profile tool contains basic user information, including names, and other optionally displayed information.  

Your Profile is available in all of your sites throughout the system. It contains information about you, such as status messages, your photo, biography, contact information, social networking information (e.g. Twitter integration), connections, notification preferences, and privacy settings. Some institutions update fields in the Profile automatically when user accounts are created. Typical institutional updates include the user photo and email address. All Profile fields are optional.

Note: Some Profile options may be locked or unavailable depending on institutional settings.
