what is the coccygeal cornu - it just directs to coccyx ? --Iztwoz (talk) 12:49, 20 June 2015 (UTC)
"Horn of coccyx" if translated. Found in original Gray's Anatomy: 
Surfaces.—The anterior surface [of the coccyx] is slightly concave, and marked with three transverse grooves which indicate the junctions of the different segments. It gives attachment to the anterior sacrococcygeal ligament and the Levatores ani, and supports part of the rectum. The posterior surface is convex, marked by transverse grooves similar to those on the anterior surface, and presents on either side a linear row of tubercles, the rudimentary articular processes of the coccygeal vertebræ. Of these, the superior pair are large, and are called the coccygeal cornua; they project upward, and articulate with the cornua of the sacrum, and on either side complete the foramen for the transmission of the posterior division of the fifth sacral nerve.
Thanks Tom (LT) it is actually writ up on coccyx page! It is a redlink there - do you think the link needs removing as there's not much else can be added there? Also when items are merged to pages and the links remain on templates should they be kept or removed? Thanks again --Iztwoz (talk) 16:27, 21 June 2015 (UTC)
