Generate list of field names and descriptions for tables in Access

I have the following code I am running to build a data dictionary.  I want the dictionary to contain field names and descriptions for each table.  I can get the names fine, I just can't figure out how to get the descriptions.  Here is my code:
Sub ExamineTable(TableName As String)
Dim currentDB As Database
Dim mytable As TableDef
Dim fieldName As String
Dim fieldDescription As String
Dim i As Integer

Set currentDB = Application.currentDB
Set mytable = currentDB.TableDefs(TableName)

   
For i = 0 To mytable.Fields.Count - 1
    fieldName = mytable.Fields(i).Name
'THIS IS WHERE IT BLOWS UP (BELOW).  I DONT KNOW HOW TO ACCESS THE DESCRIPTION OR CAPTION
    fieldDescription = mytable.Fields(i).Description
   
    DoCmd.RunSQL "Insert tblDictionary (FieldName, FieldDescription) " _
        & "Values ('" & fieldName & "','" & fieldDescription & "');"

    Next i

End Sub
