Nape piercing
Somewhat less common are surface anchors, commonly made from surgical implant-grade titanium. A surface anchor has two parts: a base or foot which is inserted under the dermis during the piercing process and which incorporates a stem exposed to the surface, and a decorative disc or ball of jewelry which typically appears flush with the surface of the skin. Surface anchor nape piercings are most commonly found placed symmetrically on either side of the spine at the nape.
Anchor paper
An anchor paper is a sample essay response to an assignment or test question requiring an essay, primarily in an educational effort. Unlike more traditional educational assessments such as multiple choice, essays cannot be graded with an answer key, as no strictly correct or incorrect solution exists. The anchor paper provides an example to the person reviewing or grading the assignment of a well-written response to the essay prompt. Sometimes examiners prepare a range of anchor papers, to provide examples of responses at different levels of merit.
