The eggs of the crab louse are laid usually on the coarse hairs of the genital and perianal regions of the human body. Crab lice may also be found on other areas of the body that have coarse and relatively sparse coverings of hair, such as the beard, moustache, eyelashes, underneath the arms.
Quotes within quotes. When a run-in quotation contains quotation marks within the quoted material itself, use single quotation marks in their place. When the material being quoted contains a quotation within a quotation (i.e., something in single quotation marks), use double quotation marks.
Using Quotation Marks. The primary function of quotation marks is to set off and represent exact language (either spoken or written) that has come from somebody else. The quotation mark is also used to designate speech acts in fiction and sometimes poetry.
