Look up APA style on google - plenty of examples

What style are you using? APA? MLA? What are you trying to cite??

Try Harvard Style as well. You will need to use the appropriate style for your institution and area as there are different types, and usually referencing is equally as important as your actual paper.

It is really impossible to give you the help you are asking for without know what kind of citation you are supposed to be using. The best I can offer you is a great web site that lets you plug information in and spits a citation out. It does MLA, APA, and Chicago. http://citationmachine.net/

Perhaps the most common is the Harvard style of referencing. Individual journals use this with very slight differences, but the principle remains the same. In the actual text you would place a superscript number - the first work you reference being number 1, etc. So if you reference article A first, you could say Blood pressure is maintained by both parasympathetic and sympathetic autonomic control1. (the number 1 would be in superscript in your version, I just don't know how to on this site. If using word, you highlight the number and go to Format, Font, then tick superscript). Then in your reference list you would put 1 Names of authors Year of Publication, "Article title", Journal Title in italics, Volume and page numbers. If you used more than one reference, it would be numbered as so. Blood pressure is maintained by both parasympathetic and sympathetic autonomic control1. Sympathetic control is actioned via the hormone adrenaline and is replicated in acute hospital settings2, maintenance of blood pressure is vital in resuscitation1,2. Remeber that both the numbers 1 and 2 should be in superscript in your version. So I referenced article 1 for the first sentence, then article 2 for the first half of the second sentence, and both articles 1 and 2 for the last half of the second sentence. In your reference list at the end, you would only need to list the articles once each, making sure that the number you used in your text matches the number given to them in the list. If still in doubt, check out this link or do a search for Harvard referencing styles. You will probably use the journal or chapter in an edited book part most. http://www.usq.edu.au/library/help/ehelp/ref_guides/harvard.htm
