How to use multiple styles within a single paragraph in MS Word

Is it possible to use more than one style in a single paragraph in MS Word? Ideally, I would like each new paragraph to start with an outline number, then a bold/underlined heading, followed by unstylized text.

E.g.,

1. Section One. Regular body text goes here.

When I attempt to use more than one style within a paragraph, the entire paragraph appears to automatically change to whatever style I select from the drop-down menu.

If this question is better suited for another StackExchange forum, I'd appreciate a nudge in the right direction. Thanks in advance.

The only way you can achieve this is through the use of Character styles. Character styles are intended for small portions of text like captions and footnote referencing. You can use a paragraph style for your main paragraph text and then apply the character style to the 'Section One' text.

Use a style separator. It's explained at http://www.addbalance.com/usersguide/complex_documents.htm#Style_Separator

I rewrite condo and association documents from photographed pictures of those documents. Although my versions may not be legal copies, they are more granularly organized and searchable.

For those instances in which the original text says something like:

20.1 Determination of Common Expenses. The Association, through its Board of Directors, shall ...

I have a style, Heading 3, that in this case is bold and numbered, while the subsequent physical paragraph is neither. I accomplish this by separating the Heading 3 style text from the rest of the physical paragraph using a hidden paragraph mark:

• Hit Enter/Return to create a paragraph mark, then select only the paragraph mark and change its Format to Hidden [Alt+o>f, toggle Hidden].

This separation paragraph mark solves styles' requirement for headings to be in their own paragraph, and allows the heading to be on the same line as the rest of the paragraph when printed or saved as a PDF file.

When Show/hide is toggled ON, paragraph marks and hidden text are displayed; when toggled off, these disappear and the pages render as they will be seen when printed.

I've used this "inline styles" method since Word 2000; now in Word 2010.
